Top Rental Yield Suburbs in Australia 2026: Where Cash Flow Actually Lives Now

Published 4 September 2025, updated 5 October 2026

Key takeaways

• Darwin is the only capital averaging above 6%. Its 6.5% dwelling yield is nearly double Sydney's 3.4%, and it was the only capital where values rose over the September quarter (+0.5%).
• Units beat houses on yield in all eight capitals, by 0.5 to 1.7 percentage points: Sydney 4.4% against 3.0%, Melbourne 5.2% against 3.5%, Perth 5.2% against 3.9%, Darwin 7.5% against 6.0%.
• The national gross yield is 3.85%, the highest since August 2019; the combined-capitals figure is 3.7%, up from a 3.34% low in December 2025. Falling values and rising rents are both doing the work, but the rent leg is slowing.
• Only 38 suburbs nationally, 0.8% of the total, are positive cash flow at a 20% deposit on Cotality's June 2026 modelling. Just two are in capitals. Our own cash-flow table below reproduces that result from the suburb data independently.
• The 2025 yield frontier has moved. Perth's 2025 leaders compressed as values ran ahead of rents, Brisbane's 4.2% unit yield is now the lowest of any capital, and the yield now sits with Darwin, inner-Melbourne units, Perth's sub-$800K belt, Adelaide's infill precincts and diversified regional centres.

What Changed Since Our 2025 Edition

Three changes since our 2025 edition have moved rental yield to the centre of the investment case.

The reform. The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on 26 June 2026. For established dwellings acquired under contracts entered after 7:30pm AEST on 12 May 2026, rental losses can no longer be offset against wages from 1 July 2027; they are quarantined against residential-property income instead. New dwellings are carved out, pre-cut-off holdings are grandfathered, and SMSFs are exempt. Our complete negative gearing guide and transition plan carry the mechanics. Cotality drew the consequence in June: investors who can offset less of a rental loss against taxable income will pay more attention to yield.

The rates. The Reserve Bank raised the cash rate to 4.60% on 29 September, its fourth rise of 2026 after February, March and May, and said it would raise again if needed. On the RBA's Lenders' Interest Rates table for July, new interest-only investment loans averaged 6.50%; with the September rise passed on in full, that is about 6.75%, the rate we use throughout this article. Investor demand had already responded before the latest rise: ABS Lending Indicators for the June quarter show new investor loan commitments down 8.6% in number and 10.2% in value, the largest quarterly fall since the September quarter of 2022.

The prices and rents. Cotality's September index has national values down 3.7% over three months and 5.2% below their March 2026 peak after a sixth consecutive monthly fall, with Sydney 8.6% below its February peak and 97% of capital-city suburbs lower over the quarter. Rents rose 5.5% nationally over the year. Falling values against rising rents lifted the combined-capitals gross yield from a record low of 2.92% in January 2022, through a 3.34% cyclical low in December 2025, to 3.7% in September. The national figure is 3.85%.

The callback. Our 2025 edition led with Melbourne CBD units at 8.6% and Parmelia units in Perth at 8.2%, put Perth's city-wide unit average at 5.8%, and picked Brisbane on Chermside units at 5.2% and Newstead houses at 4.5%. Perth values are still 10.1% higher than a year ago and its unit yield is now 5.2%. Brisbane's inner-unit yields compressed further still. The 2026 tables below are materially different, because suburb yield leaders show where prices have lagged rents, and that changes fast.

How to Read a Rental Yield in 2026

The suburb tables in this article report gross yields because that is what the source datasets publish. Read them with three adjustments.

Gross to net. A 6% gross unit with $4,000 of strata, $2,500 of rates and water, 7% management, a maintenance allowance and two weeks' vacancy is usually a 3.5% to 4% net proposition. Houses lose less to strata and more to maintenance. Our rental yield calculator shows gross and net side by side and benchmarks against each capital's median.

Net to cash flow. The break-even depends almost entirely on leverage.

Assumptions: our arithmetic. Interest rate is an assumed post-hike rate: the RBA Lenders' Interest Rates (Table F6) average for new interest-only investment loans funded in July 2026 (6.5%) plus the 25 basis point rise of 29 September 2026, assuming full pass-through. Holding costs of 1.5% of value for a house and 2.5% for a unit cover rates, insurance, management, maintenance and, for units, strata; they are the same bands used in the cash-flow table below. Excludes vacancy, acquisition costs, land tax and depreciation. Illustrative only; our yield expansion article runs the same arithmetic across more scenarios.

The 2026 wrinkle. For an established dwelling bought after the 12 May 2026 cut-off, the gap between net yield and interest cost is no longer softened at tax time from July 2027, so positive cash flow becomes the practical target.

Serviceability. Lenders assess at the actual rate plus APRA's 3 percentage point buffer, so roughly 9.75% on a 6.75% loan, and most shade rental income to 70% to 80% in the assessment. A high-yield property helps you borrow, but not at face value.

The National League Table, September 2026

Source: Cotality Home Value Index, September 2026 (index results to 30 September 2026, released 1 October 2026), as first published: gross yields by dwelling type, three-month value change, and annual rent change for the capitals (houses and units; the release does not publish rent change by city for all dwellings or for the regions). National rents rose 5.5% over the year for all dwellings. Regional NT dwelling yield is Cotality's chart figure; its unit yield and three-month change are not published. Vacancy: SQM Research National Residential Vacancy Rates, August 2026 data (released 15 September 2026). See our vacancy rate tracker for the monthly series.

The table shows two constants. Units out-yield houses everywhere, by between 0.5 points (Hobart) and 1.7 points (Melbourne). And yields run opposite to prices: Darwin's median dwelling is $633,431 and Sydney's $1,198,596, and Darwin yields almost twice as much.

The value column is what changed in 2026. Seven of eight capitals fell over the quarter, so the denominator is shrinking under every yield at once. Sydney's fall (−4.9%) is the sharpest, and its rent growth (houses +4.9%, units +3.7%) is below the national pace, so most of Sydney's yield expansion is price-led. Perth's fall (−4.7%) sits under rent growth of 8.0% for houses, so its expansion is still mostly rent-led. That distinction, between income you will receive and a smaller capital base under the same rent, runs through every city section below.

The counterargument: the rent leg is slowing

The whole case for yield expansion assumes rents keep rising. That assumption weakened in the most recent data. Cotality's September index has national rents up only 0.3% over the month (seasonally adjusted), the smallest monthly rise since May 2025, and its own national vacancy measure has risen to 2.0% from a record low of 1.5% in February. SQM Research's 15 September release had national advertised rents flat over the month to 4 September. SQM's Louis Christopher was blunt: "The annual rent figure of 7.3% is history. It reflects increases that have already stopped." He set a dated test: asking rents normally firm from October into the summer leasing season, and if that seasonal lift fails to appear in the larger capitals, the rental upswing there is over.

The first read on that test is mixed. SQM's weekly series for the week ending 4 October has the national combined asking rent at $705.61, up 0.6% over the month, but the gain is all houses (+1.4%); unit asking rents fell 0.7%. Cotality's rental index is a smoothed, quality-adjusted measure of advertised rents; SQM's weekly series is raw asking rents and moves faster. If unit rents keep softening through spring, further yield expansion in the unit-heavy tables below comes from falling prices alone.

Sydney: Yield at the Margins

Source: realestate.com.au data as reported by API Magazine, "Highest rental yields throughout Australia revealed", 27 May 2026. Sydney-wide averages: Cotality Home Value Index, September 2026.

Sydney combines the lowest capital-city yield with the sharpest quarterly price fall. Values are 8.6% below their February 2026 peak and 7.0% lower than a year ago. In Cotality's September chart pack (August data), upper-quartile houses were down more than 10% and the median vendor discount had widened to 4.5%. Rents are still rising on Cotality's rental index, but Sydney unit rents (+3.7%) are rising more slowly than anywhere except Canberra, and SQM's August vacancy rate for Sydney is 1.7%, 26% higher than a year ago. Total listings in the four weeks to 6 September were 11.3% above last year even with new listings down 18.8%, so stock is accumulating because it is not selling.

Most of Sydney's yield rise comes from falling prices, not rents. A Sydney house at 3.0% gross that becomes 3.2% because its value fell 7% is a cheaper asset under the same rent. In our view the only durable 6%-plus pockets are western and inner-city units near transit and universities, where student, health and service-worker demand keeps rents firm against a unit price base that has lagged houses for years. Ultimo and Auburn fit that description. Both carry the caveats of older high-density stock: strata levies that can absorb a full point of yield, defect risk, and thin resale depth while investor demand retreats.

The Central Coast house entries and Gilead in the south-west are a different proposition: fringe estates with newer housing, 4.2% to 4.9% gross, and exposure to the part of the Sydney market that was falling least in the chart pack's August read (the lower quartile, down 2.1% for the quarter), trading some yield for growth exposure.

Melbourne: Inner-City Units Lead the Country

Source: realestate.com.au data as reported by API Magazine, 27 May 2026 (12 months to April 2026); Smart Property Investment highest-yield suburb tables, updated 7 September 2026 (data feed undisclosed). Where two sources print different figures for the same suburb both are shown; the gap reflects different rent and price windows, not an error in either.

Melbourne is the only large capital where a deep, diversified market produces 7%-plus suburb yields. Our reading is that inner-city unit prices have gone nowhere for years (Melbourne dwelling values are 5.5% lower than five years ago on Cotality's index) while rents have followed the city's population and university intake upward.

The CBD shows why a single yield figure deserves scepticism: SPI prints 8.52% and REA 7.26% for the same suburb, because each pairs a different rent and median. Both are arithmetically correct; they describe different slices of a mixed stock of student studios, older walk-ups and newer towers. If you are buying in the inner city, the only yield that matters is the one calculated on the actual asking price and the achievable rent for that specific dwelling.

The cash flow is real, though. Carlton is one of only two capital-city suburbs in Cotality's positive-cashflow research, the Metro Tunnel is now open, and student, health and hospitality demand in the inner north does not depend on the property cycle. The growth record is the caveat, and our reading is that the apartment completions of the last decade in the CBD and Southbank are the supply-side reason for it. We read the inner-Melbourne unit belt as an income asset with a weak growth record: an investor who buys Carlton at 9% gross and underwrites 6.6% net should model strata levies, special levies on older towers, and a tenant base that turns over annually.

The house entries are outer-fringe growth-corridor stock (Clyde) or lifestyle-regional overlap (Warburton, Hastings) at 4.3% gross. Melbourne values fell 3.4% over the September quarter, and Cotality notes the city is now falling more slowly (−0.7% in September) than each of the mid-sized capitals. In the chart pack's August read the upper quartile was leading the falls and the lower quartile was down only 1.3%, so the fringe is holding better than the middle. A 4.3% yield at a $650,000 to $750,000 entry is a more balanced proposition than the same yield in Sydney at $1 million-plus. Our four signals for buying in Melbourne sets out when the growth side of that equation turns.

Brisbane: Yields Compressed by the Boom

Source: realestate.com.au data as reported by API Magazine, 27 May 2026; Fortitude Valley and Spring Hill units were named as strong performers without figures. Logan Central: our Top 10 Suburbs September 2026 verification against Cotality-family suburb data, with postcode-level vacancy of 0.45%. Brisbane-wide averages: Cotality Home Value Index, September 2026.

The boom reached Brisbane's yield frontier first. Our Top 10 series picked the Logan and Ipswich corridor through 2025 and into April 2026 on sub-$650,000 entries at 5%-plus with tight vacancy. Brisbane values are still 5.9% higher than a year ago even after a 4.7% fall over the September quarter, and Logan Central units now print 4.61% at $506,000. In our September edition they pass both screening gates but score outside the top ten, held back by yield.

What is left is thinner than the table suggests. The bay islands print 4.6% to 5.3% because prices are low, and prices are low because the islands have ferry-only access, limited services and a resale market measured in a handful of sales a month. CBD-fringe units are the diversified-demand option, with an Olympic construction pipeline and the state's supply shortfall behind them. Logan Central units at 4.61% on 0.45% postcode vacancy combine yield with tight suburb-level demand, though they still sit well below break-even at any normal leverage.

Brisbane's house rent growth (+6.7% for the year) is the second-fastest of the large capitals after Perth, unit rents rose 5.9%, and total listings in the four weeks to 6 September were 53.3% above last year. Brisbane was the sharpest-falling capital in September (−1.5%). We expect its yields to expand from both sides over the next year, with rents still rising and prices now falling, but from a compressed base that leaves entry yields below the national average for at least the next cycle.

Perth: The Last Boom Market's Yield Remnants

Source: REIWA, "Perth's top performing suburbs for rentals in 2025-26", 13 July 2026 (financial year to 30 June 2026); realestate.com.au data as reported by API Magazine, 27 May 2026. REIWA's unit list continues with Glendalough, Spearwood, Perth, Rivervale and East Perth. Perth-wide averages: Cotality Home Value Index, September 2026.

Perth's 2025 tables aged fastest. A year ago Parmelia units printed 8.2% and Perth CBD units 7.4%; REIWA's whole-of-FY26 top unit yield is now Beckenham at 6.6%. The compression is price-driven. Perth's median house rent reached $750 a week (+9.5% over the financial year) and units $700 (+7.7%), and Cotality has Perth house rents up 8.0% for the year to September, the fastest of the large capitals. Prices ran further than rents.

Two things changed in the last quarter that matter more than the suburb list. Values turned: down 4.7% over the three months to September and 6.0% below their April peak, although still 10.1% higher than a year ago. Supply also arrived. Cotality's total listings for Perth in the four weeks to 6 September were 53.3% above last year, and REIWA's for-sale count reached 6,718 at the end of July, up 101.9% year on year. That matches Brisbane as the fastest stock rebuild of any capital and is the first real threat to Perth's rent-growth run. Vacancy is still 0.6%, with a listings pipeline behind it.

In our view Perth's remaining sub-$800,000 house belt with delivered infrastructure is the best yield-and-growth overlap in any capital, because prices are now falling into a still-tight rental market. Midland (4.7% on REIWA's FY26 list, station opened February 2026, hospital and TAFE campus; houses $695,000 at 4.58% and units $570,000 at 5.50% in our September Top 10 data, where the units made the list) and Cannington (5.0% houses on REIWA's list; units $625,000 at 5.61% on 0.49% postcode vacancy in our September edition) are the cases in point, and Armadale houses ($666,000 at 4.58%) remain in our September top ten. Beckenham's 6.6% unit yield tops REIWA's list, but measured on Cotality's basis in our September edition it is 5.6% at a $540,000 median, which shows how much the source matters. Perth units also fell 5.1% over the quarter, more than Perth houses.

Adelaide: Tight, Cheap, and Yield-Thin at the Top

Source: realestate.com.au data as reported by API Magazine, 27 May 2026; Smart Property Investment highest-yield suburb tables, updated 7 September 2026; Salisbury median and yield from our Top 10 Suburbs September 2026 verification against Cotality-family suburb data. Adelaide-wide averages: Cotality Home Value Index, September 2026.

Adelaide has tight vacancy and rising rents, but its yields are thin. Vacancy is 0.6% on SQM's August count, rents rose 6.3% for houses and 6.1% for units over the year, and values had the mildest September-quarter fall of the five large capitals (−2.7%). That resilience is why the yields are thin: Adelaide's median house is $990,531 on Cotality's September index, and the northern corridor that supplied the 2025 edition's 6%-plus entries has repriced.

Salisbury shows how quickly a yield story reprices. Older figures that still circulate put it at a $361,000 median and a 6.3% yield. Our September Top 10 measures a $525,000 unit median at 5.05% after about 31% trailing growth, so the "under $400,000 metro yield" framing no longer applies. On those numbers it passes both of our screening gates (0.52% postcode vacancy and a 5.05% yield) and ranks 13th, with the Edinburgh defence and manufacturing base behind local demand.

The metro infill entries worth a sentence are Tonsley (6.58%) and the inner-suburban Hawthorn units (6.39%), both employment- or amenity-anchored rather than fringe stock. They are the Adelaide exceptions to the rule that capital-city 6%-plus lives only in Darwin and inner Melbourne, and both should be checked against the strata and body-corporate costs that infill precincts carry.

Cotality dates Adelaide's peak to May 2026; values are now 2.9% below it. The yield maths improves with every month of that: a 3.5% house yield becomes about 3.9% at a 10% price fall with rents flat, and Adelaide's rents are still rising about 6% a year.

Darwin, Hobart and Canberra: The Smaller Capitals

Source: realestate.com.au data as reported by API Magazine, 27 May 2026; Smart Property Investment highest-yield suburb tables, updated 7 September 2026 (SPI's tables do not split house and unit). City averages, value and rent changes: Cotality Home Value Index, September 2026. Vacancy: SQM Research, August 2026.

Darwin leads every column of the national table, and it earns the position. Values are within 0.2% of their July record after an 11.9% annual gain, house rents rose 11.4% and unit rents 12.0% for the year, vacancy is 0.4% and the median dwelling is $633,431. Berrimah is one of only two capital-city suburbs in Cotality's positive-cashflow research. The caveats are the ones that have always applied: a thin market where a few hundred sales a quarter set the medians, an economy weighted to defence, public administration and resources, and a price history that includes a decade-long flat spell from 2014. Like a mining town, Darwin carries real cycle risk. The difference is that Darwin is a capital with a public-sector base and a growing defence footprint, which in our view makes it the most defensible high-yield market in the country. Watch the supply line: in the four weeks to 6 September, Darwin's total listings were up 19.4% and new listings up 19.3% on a year earlier.

Hobart yields 4.4%. House rents rose 8.7% for the year, second only to Darwin; vacancy is 0.6%; values fell only 1.2% over the quarter and are 2.0% below their March 2022 peak, so Hobart has already been through its downturn while the mainland starts one. Gagebrook and Herdsmans Cove, the northern-suburbs house belt at 5.9%, are cheap-entry, high-yield, low-growth stock with a tenant profile that requires careful management. New Town (5.66%) and Dynnyrne (5.5%) are the inner alternatives.

Canberra yields 4.4%, which looks respectable until it is read against unit rent growth of 1.5%, the loosest SQM vacancy in the country at 2.1%, and a value fall of 3.2% over the quarter. Canberra's yield is expanding because prices are falling into a market where unit supply has outrun a public-service-dominated tenant base. Red Hill (8.18%), Phillip (7.49%) and Curtin (7.38%) print high unit yields for the same reason inner Melbourne does, flat unit prices, but without Melbourne's population growth to backstop rents. Canberra fails the vacancy check in the screen below and is marginal on price trend, so a 7% unit yield there is a different asset from a 7% unit yield in Darwin.

Regional Australia: The 10%-Plus Club and Its Rules

Source: Smart Property Investment highest-yield suburb tables, updated 7 September 2026 (data feed undisclosed; tables do not split houses and units). The Northern Territory row excludes Greater Darwin and Palmerston suburbs, which appear in the Darwin table above. Broad-region yields: Cotality Home Value Index, September 2026. Regional WA and Queensland figures are corroborated in realestate.com.au data reported by API Magazine, 27 May 2026 (Coolgardie houses 11.5%, Newman units 13%, Pegs Creek units 12.9%).

Three rules apply.

Single-industry towns pay you for volatility. Cotality's positive-cashflow list is 69% regional WA with a strong skew to the Pilbara, and a further 10% Bowen Basin coal towns, which Cotality describes as markets with higher volatility and low-to-negative capital gains historically. Pilbara values fell hard in the last mining downturn, so a 13% yield on today's price says little about what the previous owner paid. Buy these only with cash you can afford to see halve, and underwrite the rent at the level a downturn tenant pays, not a boom contractor. South Hedland, Bulgarra, Pegs Creek, Millars Well, Baynton, Port Hedland, Nickol and Newman are all Pilbara; Kambalda East is Goldfields; Pioneer, Winston, Menzies, Townview and Happy Valley are Mount Isa suburbs; Cloncurry is a north-west Queensland mining town; Dysart, Blackwater and Clermont are Bowen Basin. Nine of the top ten in both WA and Queensland are resource markets; the exceptions are Cable Beach (Broome) and Bucasia (Mackay's northern beaches).

Regional WA is currently yield and growth. Values rose 14.1% over the year to September, the strongest broad region in the country, and fell only 1.0% over the quarter. That is the commodity cycle and the state's population inflow at work, and both can reverse.

The sustainable middle is where our Top 10 hunts. Between capital thinness and mining-town risk sits a band of regional centres with diversified employment (university, health, government, agriculture, freight) at 5% to 6% gross. Launceston's northern belt leads it on our September data: Mowbray houses at $540,000 and 5.14% (our September number-one house), Ravenswood at $442,000 and 5.66% (a thin market of 44 sales), and Newnham at $605,500 and 5.0%, on postcode vacancy of 0.63% to 0.75%. Mackay units ($402,000 at 6.07%; North Mackay $430,000 at 5.38%, on 1.24% postcode vacancy) and the Tasmanian and Adelaide infill entries fill out the band. Armidale shows the screen working: its units yield 5.70% at $400,000, but its postcode vacancy is 2.85% on our September measure, which takes it out of our shortlist for now. Apply the five-check screen below to each: Roxby Downs (one employer), Queenstown and Zeehan (mining hamlets) and the Port Pirie entries (smelter) pay for concentration; South Launceston, the Launceston northern belt, Tonsley and the diversified coastal centres are the standouts. Our regional property investment guide covers the resource-town cycle in full.

A Warning About "Fastest Growing Suburb" Tables

We use the Smart Property Investment yield tables in this article, and we do not use the growth tables from the same page.

They contradict the measured market. The 7 September edition has Waverton up 48.43% and Lavender Bay up 46.14% for the year, with Burraneer at 49.08%. Cotality's index has Sydney down 7.0% over twelve months and 8.6% below its February peak, with upper-quartile houses more than 10% below peak. Waverton, Lavender Bay and Burraneer are all upper-quartile harbourside markets, which is precisely the segment the index says is falling fastest.

Thin markets produce the extremes. Nearly every extreme entry is a thin market: a harbourside pocket, a village, a mining hamlet. Ten sales a quarter means the "median" can be one family's renovation. The same defect appears in the yield tables, just smaller: Melbourne CBD units print 8.52% on SPI and 7.26% on REA, and South Australia's current top ten prints Roxby Downs twice, at 8.67% and 7.4%, presumably for different dwelling types.

The rule for readers. Yield tables are rent-to-price ratios and hold up reasonably well when the mix of sales changes, because both sides move together. Growth tables are median-to-median deltas and are not. Read every suburb figure as a band, and use suburb growth lists as leads for verification against an index-based source, never as rankings.

The Cash-Flow Reality Check: What These Yields Return in Cash

High yield and positive cash flow are different claims. Cotality's research director Tim Lawless described finding a positive cash flow property as "the proverbial needle in a haystack", and the mortgage alone accounts for about 71% of an investor's costs in that modelling. Cotality's September release repeats the point: even with yields rising, "opportunities for neutral to positive cash flow remain low". The table below converts the article's own headline yields into a pre-tax cash position, so readers can see the gap.

Assumptions: our calculation, illustrative only. Net yield deducts 1.5 percentage points for houses and 2.5 for units (rates, insurance, management, maintenance and, for units, strata), consistent with the cost band used earlier in this article; entries whose source does not split house from unit (South Hedland, Mount Johns, Queenstown) use the house band, as those markets are predominantly detached. Cash position is net yield less interest at an assumed post-hike 6.75% interest-only rate (RBA Table F6 July 2026 new-investor interest-only average of 6.5% plus the 29 September rise) applied to the stated LVR: 5.4% of value at 80%, 4.05% at 60%. Excludes vacancy, land tax, acquisition costs, tax effects and principal repayments. Gross yields and their sources are as shown in the city and regional tables above. Beckenham uses REIWA's 6.6%; on our September Cotality-basis 5.6% it would be −2.3% at 80% LVR and −1.0% at 60%.

First, the two capital-city suburbs that clear break-even on our arithmetic, Carlton units and Berrimah houses, are the same two capital-city suburbs in Cotality's independently produced list. That result came from applying our cost band and the RBA's rate to published suburb yields, so the two methods corroborate each other.

Second, the answer moves with the financing assumption. Cotality models 30-year principal and interest at 6.34%, which costs about 6.0% of value a year at 80% LVR rather than our 5.4% interest-only figure. On that stricter basis Queenstown and Travancore fall below break-even and Berrimah sits almost exactly on it. Either way, a gross yield on a listing tells you little until the loan is specified.

Check which claim a listing is making, because listing copy routinely conflates the two. Treat leverage as the main lever: even Cotality's optimistic scenario, a 10% value fall combined with a 10% rent rise, lifts the combined-capitals yield only from 3.45% to about 4.27%, which its research describes as still a long way from positive cash flow after costs. And note the pricing wedge the reform creates: a pre-cut-off holder can still offset losses against wages, while a buyer after 12 May 2026 cannot from July 2027, so established high-yield stock is worth relatively more to grandfathered holders than to new buyers. New buyers should underwrite established stock on cash flow alone. Our positive cash flow property guide works through the full-cost method.

Sustainable Yield or Falling Knife: The Five-Check Screen

Source: our framework, as used in the Top 10 Suburbs series. Thresholds are judgement calls, not published standards.

Four worked contrasts. Mowbray passes the vacancy and employer-diversity checks (0.63% postcode vacancy, the Launceston employment base); rent affordability and the five-year price trend need checking against local incomes and a longer price series, especially after about 24% growth over the past year, so its 5.1% house yield reads as promising rather than proven. A Pilbara town passes one or two (vacancy is tight, but one commodity, cyclical population, contractor rents and a five-year price chart shaped like a saw), so its 11% to 13% yield reads as payment for volatility. Canberra's unit precincts fail the vacancy check and sit on the margin of the price-trend check (values +3.1% over five years but −1.6% over the past year), and inner-Melbourne units fail the price-trend check outright: Melbourne dwelling values are 5.5% lower than five years ago, which is why we read Carlton as an income asset rather than a growth one.

The Bottom Line

• Yield is now the central number in any purchase made after 12 May 2026, because the enacted reform, the SMSF borrowing ban and an assumed investor rate of about 6.75% have removed the supports that made a deep shortfall tolerable.
• The yield frontier has moved out of the boom capitals' affordable corridors, which repriced, and toward Darwin, inner-Melbourne units, Perth's remaining sub-$800,000 belt, Adelaide's infill precincts and diversified regional centres.
• Yields are rising mechanically, from 3.34% to 3.7% across the capitals since December 2025, and every published price forecast lifts them further.
• But almost nothing is actually cash-flow positive. Only 0.8% of suburbs clear the bar on Cotality's modelling, and our own arithmetic puts just two capital-city suburbs above break-even at 80% LVR. Underwrite net, not gross, and stress-test at the 3-point serviceability buffer.
• Use the tables as a shortlist, not a ranking. Every figure here is a snapshot from a labelled window, and the same suburb can print yields more than a point apart across providers (Melbourne CBD units: 8.52% on SPI, 7.26% on REA).

What would change this call

We would revise the view in this article if any of the following happened, and each is checkable on a published release.

• Asking rents fail the spring test. Cotality's rent index is slowing and SQM's unit asking rents fell over the month to 4 October. If the October-to-January seasonal lift does not appear in Sydney, Melbourne and Brisbane, the rent leg of yield expansion is finished and every yield in this article becomes purely price-driven.
• Darwin's supply catches up. Darwin carries this article's highest capital-city yields on 0.4% vacancy, but its listings were already up about 19% year on year in early September. SQM vacancy above 1%, or another 20% of listings growth, would remove the tightness the yield depends on.
• The cash rate moves to 4.85% on 3 November. Westpac and ANZ expect that; CBA, NAB and AMP expect a hold. A further 25 basis points would lift the 80% LVR break-even from about 6.9% to 7.1% gross for a house and from 7.9% to 8.1% for a unit, leaving Carlton (+1.0) and Berrimah (+0.5) above the line on our arithmetic and taking the rest of the capital-city table further below it.
• Inner-Melbourne unit yields compress below 7% on the next REA and SPI updates, which would mean the unit price base is finally moving and the highest large-capital yields in the country are closing.
• Regional WA's commodity cycle turns. The Pilbara entries carry the country's top yields on the strongest regional value growth (+14.1% for the year). A reversal would hit both halves of the ratio at once.
