SQM National Vacancy April 2026: First Rise in 12 Months — 1.2% Signals the Turning Point

For the first time in 12 months, Australia's residential rental vacancy rate has lifted. SQM Research's 12 May 2026 bulletin shows the national rate rose from 1.0% in March to 1.2% in April, a 20-basis-point shift that adds 3,526 dwellings to the available rental stock nationally. It is the first material monthly rise in the headline rate since early 2025.

At face value, the move looks small. In context, it is the cleanest directional shift the rental market has produced in over a year — and it has arrived precisely as the Federal Budget reshaping investor tax policy was being handed down. SQM's managing director Louis Christopher framed the moment plainly in the bulletin:

"With regard to the impending property tax changes, we have previously done rigorous modelling on a pullback of negative gearing scenario. While I have no doubt in my mind this change is going to put additional pressure on the rental market, the time for talking is now over. We will soon see actual data come through."

This piece reads the 12 May bulletin three ways — month-on-month, year-on-year, and against the decade-long baseline — then walks through the city-by-city picture, reconciles the data against the recent Cotality, NAB and Domain releases, and sets out what each cohort of investor should take from the print. We covered the March SQM data, which showed national vacancy at 1.0%, in our April 16 analysis. This is the directional follow-on: the first crack in the wall, but the wall is still standing.

1. The Headline Numbers, Read Three Ways

A single data point can be read several ways, and the right reading depends on what question the investor is trying to answer.

Month-on-month: the first rise in a year

The headline number: 1.0% in March, 1.2% in April. A 20-basis-point rise across 30 days. The absolute dwelling count moved from 31,732 vacancies nationally to 35,258 — an additional 3,526 dwellings sitting empty for more than three weeks of advertised listing.

Three months ago, the SQM print rolled in below 1.1% nationally, and the language from rental analysts and property economists was almost uniformly about "deepening crisis." This month, the same dataset shifted enough to produce the first directional reversal in the trend since 2025. The cause is partly seasonal — April typically sees a small rise in listings as autumn leases roll over and university-student rental demand transitions. But the seasonal component does not explain the full move; Adelaide and Perth, where the cycle is least seasonal, also showed marginal vacancy increases. Something more structural is at work.

Year-on-year: still tightening

The April 2025 to April 2026 comparison cuts the other way. A year ago, the national vacancy rate stood at 1.3% with 39,378 vacant dwellings. Today it sits at 1.2% with 35,258 vacant dwellings. Despite a larger total rental stock now versus then — completions have been adding inventory throughout 2025 — there are 4,120 fewer vacant dwellings year-on-year.

That YoY tightening is the part of the picture that the headline month-on-month move obscures. The rental market is less tight than it was a month ago, but more tight than it was a year ago. Both can be true at the same time, and both matter for different reasons.

Decade-on-decade: still well below the long-run baseline

Step back further. The pre-2020 "balanced market" range for national vacancy, as widely accepted across the major data houses, was 2.5–3.5%. SQM's own long-run chart, included on page 4 of the May bulletin, shows the national rate moving in that band consistently between 2010 and early 2021 before collapsing through 2021–2023.

April 2026's 1.2% is roughly half the lower bound of the historical normal. The "rental crisis" framing that has dominated coverage for two years still applies on a decade-on-decade basis, even if the most recent print has eased slightly.

2. City-by-City Vacancy Breakdown

The national number obscures three different stories playing out across the eight capitals. Below is the full SQM comparison, then a walk through which cities eased, which cities tightened, and which sit in the middle.

The full April 2026 vacancy table

The three cities that eased

Sydney — 1.1% to 1.3% (+20 bps, +1,227 dwellings). The largest city moved the most in absolute terms. Sydney added 1,227 vacant dwellings month-on-month, which is more than the total dwelling counts of Darwin and Hobart combined. Sydney is the leading indicator: rental affordability has hit a ceiling first, where tenants have the most relative income flexibility to relocate, downsize, or share-house. The SQM rent table shows Sydney house asking rents averaging $1,156.97 per week — a figure that is functionally limiting for a meaningful share of the tenant cohort.

What we are seeing in Sydney is not an oversupply story. It is a demand-cooling story driven by affordability. Listings that would have leased in a week through 2023 and 2024 are now sitting for two to three weeks. Landlords are increasingly accepting lower-priced applicants rather than holding out for asking rent.

Canberra — 1.1% to 1.4% (+30 bps, +173 dwellings). Canberra produced the largest percentage move of the eight capitals. The drivers are likely public-sector hiring slowdown and post-election political-staff turnover, but the structural story is also an affordability one: Canberra rents moved up sharply through 2023–2024 against a backdrop of relatively flat public-service wage growth. The next two prints will tell us whether April was a one-off or the start of a trend.

Hobart — 0.4% to 0.5% (+10 bps, +19 dwellings). Hobart's move is small in absolute terms — only 19 additional vacant dwellings — but represents a 25% increase in available stock from a tiny base. The market remains extremely tight; the easing is from "almost impossible to find a rental" to "very difficult to find a rental."

The three cities still tightening

Darwin — 0.4% to 0.3% (–10 bps, 75 vacant dwellings total). Darwin remains the tightest rental market in the country, and it tightened further in April. Just 75 vacant dwellings exist in the entire city under SQM's three-week methodology. That is statistically remarkable: Darwin's total dwelling stock runs into the tens of thousands, and only 75 of them are sitting empty. Drivers are resources-cycle (Inpex Ichthys LNG, mining services) and defence (Larrakeyah, Robertson Barracks, US Marine rotation), combined with a near-complete absence of new build-to-rent supply.

Adelaide — 0.7% flat (vacancies edged up modestly). Adelaide's headline rate held at 0.7%, but the underlying vacancy count drifted from 1,071 to 1,117 — 46 additional dwellings. Functionally still extreme tightness, but the directional drift mirrors what we saw in Brisbane. Defence (ASC submarine program, Edinburgh RAAF base) and manufacturing demand are holding the floor under rental demand even as some additional supply comes online.

Brisbane — 0.8% flat (vacancies edged up modestly). Brisbane is the most interesting tight market. Vacancy held at 0.8% on the headline, but the dwelling count moved from 2,662 to 2,900 — 238 additional vacant dwellings. The market is technically still in the same vacancy band, but the underlying loosening is detectable. Olympic infrastructure preparation, interstate migration from Sydney and Melbourne, and the strongest unit completion pipeline in the country are all pulling in different directions.

The cities in the middle

Melbourne — 1.4% to 1.5% (+10 bps, +530 dwellings). Melbourne has the highest vacancy rate of the eight capitals, and it ticked up another 10 basis points in April. Inner-city unit oversupply from the 2022–2023 build pipeline is still working through. Outer-suburban houses remain tight, but the headline national figure reflects the inner-city softness. Investor appetite for Melbourne new builds will be a leading indicator for what direction the Melbourne rate moves over the next 6 months.

Perth — 0.5% to 0.6% (+10 bps, +150 dwellings). Perth produced the smallest directional change of any tight-market city. After three years of extraordinary tightness — vacancy below 0.5% for most of 2024 and early 2025 — the market is starting to absorb some completions. But at 0.6%, Perth remains one of the strongest rental markets nationally and the median rent growth (6.3% YoY combined) confirms the underlying tightness.

3. Advertised Rents — The Story Behind the Vacancy Move

The vacancy data and the asking-rent data tell complementary, not identical, stories. Reading the two together is where the actionable signal sits.

National asking rents — the headline

From the SQM bulletin's rent table (week ending 11 May 2026):

• National combined asking rent average: $696.94 per week
• Capital city combined: $794.54 per week
• Monthly change: combined rents +0.7%, houses +0.5%, units +0.8%
• Annual change: combined +7.3%, houses +7.8%, units +6.5%

Three observations sit on the surface. Unit rents are running monthly faster than house rents — a partial inversion of the post-COVID pattern. Annual rent growth at 7.3% nationally is meaningfully above the 5.9% NAB Housing Monitor was reporting last quarter, suggesting the rent picture has accelerated even as the vacancy picture has eased. And the capital-city combined average has crossed the $794/week threshold, which puts median weekly rent at roughly 41% of median capital-city household disposable income — a binding affordability number.

The divergence: rents rising even as vacancies rise

The puzzle worth sitting with: vacancies are up 20 basis points, and asking rents are up 7.3% year-on-year. These are usually inversely correlated. When they move in the same direction, something is happening in the mix.

The explanation is composition. Vacancies are concentrated in the higher-end stock, where tenants have the most relative ability to downsize, share-house or relocate when rents push above affordability. Rent rises are most acute in mid-market stock, where tenants have nowhere to go. A $1,200/week harbourside Sydney apartment sitting vacant for three weeks longer than usual coexists with a $580/week Adelaide outer-northern house signing a 12-month lease at $40 above asking on day one.

For investors, the read is sharper than the national average suggests: the yield-first sub-segment of the market is more resilient than the premium-rental sub-segment. Capital growth and rental resilience may diverge structurally over the next 18 months.

City-by-city rent growth

Rent versus vacancy in matrix form

A 2×2 reading sorts the cities into four behavioural quadrants:

• Vacancy rising + rents rising — Sydney, Hobart. Tenants stretched, but the cohort-exit pressure is just beginning. This combination is the early signature of a market starting to price-correct on the demand side.
• Vacancy falling + rents rising — Darwin. Pure landlord market. No supply, sustained demand, double-digit rent growth.
• Vacancy stable + rents rising — Brisbane, Perth, Adelaide. Structural undersupply persists; rent growth continues; the underlying tightness is intact.
• Vacancy rising + rents stagnant — Canberra. The early warning signal. When both move together in the cooling direction, the market is genuinely softening. Worth watching closely.

4. What's Driving the Modest Easing

Supply side

Completions are ticking up. NAB's April 2026 Housing Monitor — which we analysed here — reports 235,000 dwellings nationally under construction, with the heaviest pipelines in Victoria (~30% of national pipeline), Queensland (~22%), NSW (~21%) and WA (~13%). The state-by-state distribution closely matches where vacancy moved most in the SQM print.

The Build-to-Rent pipeline is beginning to add measurable stock in inner Melbourne and inner Sydney CBDs. Mirvac, Greystar, Hines, Sentinel and a growing list of institutional investors have stock either occupied or in active lease-up. The aggregate impact is still small — high single-digit thousands of dwellings nationally — but the directional effect on inner-city unit vacancy is visible in the Melbourne and Sydney numbers.

Demand side

Migration is moderating from the 2023–24 peak. Net overseas migration is projected at approximately 280,000 for 2026 per the Treasury Budget 2026 papers — still elevated by historical standards, but well below the 530,000+ peak in 2023. The mathematical effect on rental demand is meaningful: each 100,000 of migration adds roughly 35,000–45,000 dwellings of rental demand under current household-formation rates.

Rental affordability ceilings are also doing work. A median capital-city combined rent of $794.54/week represents 41% of median capital-city household disposable income — well above the 30% commonly cited as the "rental stress" threshold. In Sydney, where the house asking rent is averaging $1,156.97/week, the share of household income required is functionally beyond what the median household can afford. Tenants are responding by sharing, downsizing, or relocating to cheaper cities.

Behavioural

Three behavioural changes have shown up in industry surveys through Q1 2026:

• Share-house re-formation at multi-year highs. Flatmates.com.au reported record sign-ups in Q1 2026.
• Households downsizing their rental footprint (3-bed to 2-bed) where landlord rent rises have outpaced wage growth.
• "Movers staying" — lease renewal rates running at multi-year highs as tenants choose certainty over the risk of moving into a more expensive new lease.

The Budget 2026 wildcard

This is the part of the bulletin that will get the most attention. From the Christopher quote on page 3 of the SQM release:

"With regard to the impending property tax changes, we have previously done rigorous modelling on a pullback of negative gearing scenario. While I have no doubt in my mind this change is going to put additional pressure on the rental market, the time for talking is now over. We will soon see actual data come through."

SQM's prior modelling on a negative-gearing pullback scenario suggested investor exit would drive further vacancy compression in cities where investor share of rental stock is highest — which in Australia means Adelaide, Brisbane and inner-suburban Melbourne. The directional logic: investors who sell to owner-occupiers convert rental dwellings to non-rental dwellings, removing rental supply without removing total housing supply.

But that effect plays out over years, not months. The next three to six SQM vacancy prints will be the cleanest empirical read on the post-Budget investor behavioural response.

5. What It Means for Investors

Yield-first investors: re-validate, don't re-direct

The cities where the yield-first thesis works strongest — Darwin, Brisbane, Perth and Adelaide — are precisely the cities where vacancy did NOT ease materially in the April print. Brisbane held at 0.8%, Perth ticked up only marginally to 0.6%, Adelaide held at 0.7%, and Darwin tightened further to 0.3%. The cities where vacancy did ease (Sydney, Canberra, Hobart) are not where yield-first investors typically deploy.

Bottom line for yield-first investors: the modest national easing does not change the structural case for yield-first acquisition in the four tightest markets. If anything, the directional asymmetry strengthens the case — vacancy is rising where it doesn't matter to your strategy, and tight where it does. For deeper coverage of the yield-first thesis: Positive Cash Flow Australia 2026 and Regional High-Yield Markets 2026.

Sydney and Melbourne investors: a different read

For Sydney-focused investors, the combination of rising vacancy plus rising rents is the early signature of a tenant cohort under stress. Rental income forecasts should be modelled conservatively for 12-month re-let pricing — particularly at the upper end of the market. The base-case rent assumption that worked through 2024 needs a 3–5% haircut in scenario planning.

For Melbourne investors, the 1.5% vacancy rate is the highest of the eight capitals and ticking up. Investor leverage is being tested. Properties with poor depreciation profile, weak floor plans or in oversupplied apartment-building precincts will struggle to re-let at maintained rent. The cycle low in Melbourne is closer than the headlines suggest, but the time-on-market metric will get worse before it gets better.

Post-Budget investor cohort: watch the next 90 days

This April bulletin is, in practical terms, the last clean read of pre-Budget rental market dynamics. Field data for April 2026 was collected before the 7:30pm 12 May reform announcement.

Next month's SQM print — mid-June, covering May 2026 data — will be the first to include post-Budget behavioural response. Investors planning post-reform deployment should treat the June and July releases as the critical observations.

SMSF property investors

SMSF holders are explicitly excluded from the Budget 2026 negative gearing reforms — SMSF investor demand is structurally insulated from the policy shift. Combined with continued tight vacancy in SMSF-friendly entry cities (Adelaide 0.7%, Perth 0.6%, Brisbane 0.8%, sub-$700K segment), the SMSF acquisition window remains strong.

The risk SMSF investors should price for is not vacancy — it is lender policy. As personal-name investor demand softens and SMSF demand for tax-advantaged investment property rises, specialist SMSF lenders may tighten LVRs or DSR requirements as their books grow.

6. Reconciliation Against Other Recent Releases

The SQM bulletin sits alongside three other recent releases that bear on the rental story. Read together, they describe a consistent — if nuanced — picture.

Cotality Housing Chart Pack May 2026

Our Cotality May 2026 analysis, published earlier this morning, shows national HVI up just 1.6% over three months — the softest three-month change since April 2025. Capital-city divergence at 24 percentage points (Perth +26.0% vs Melbourne +2.0%) — the widest in Cotality's modern dataset. Yields expanding nationally for the first time this cycle.

The Cotality yield-expansion signal is consistent with what we see in the SQM rent print: rents continuing to rise at 7.3% YoY while capital growth softens. Yield expansion is the mathematical outcome of rent growth running faster than price growth — exactly the picture both datasets describe.

NAB Housing Monitor April 2026

NAB's April 2026 Housing Monitor reported ~5% national price growth forecast for 2026, vacancy at 1.6% (NAB's blended measure) and asking rent growth of 5.9% YoY. The SQM print runs slightly hotter on rent growth (7.3% vs NAB's 5.9%) and slightly tighter on vacancy (1.2% vs NAB's 1.6%). The two measures are not identical — NAB uses a broader rental-stock denominator than SQM's three-week advertised-listings methodology — but the directional consistency is high.

Domain Q1 2026 rental data

Domain's late-April Q1 2026 rental report reported Sydney median house rent stuck at $800/week for the first time in five years. The Domain measure is contracted rents, not asking rents — which explains the apparent gap between SQM's $1,156.97/week Sydney house asking rent and Domain's $800/week contracted median.

Both numbers can be true at the same time. Tenants in 12-month leases signed in 2024 are paying around $800/week. Landlords are advertising fresh stock at $1,156.97/week. The "rollover gap" — the rent rise that hits tenants when they re-sign — is therefore enormous in Sydney, which goes some way to explaining why the demand-cooling effect is visible there first.

7. The Outlook

Three scenarios for the next print

The mid-June SQM print (covering May 2026 data) is the next critical release. Three plausible scenarios:

SQM's own framing

Louis Christopher's commentary in the bulletin points to a year of "moderation" — rental growth forecast at 2–4% for 2026 nationally, implying a significant slowdown from the current 7.3% YoY trajectory. That forecast is roughly consistent with Scenario A above, but assumes a degree of investor-exit behaviour that has not yet shown up in the data.

The honest read: the moderation will happen, but it is more likely to take 12–18 months to fully play through than the 6 months SQM's framing implies. The acceleration of the Budget effect after 1 July 2027 is the key uncertainty.

What investors should do in the next 30 days

• For yield-first investors deploying into Adelaide, Perth, Brisbane and Darwin: nothing changes. The April print does not weaken the case for those four markets.
• For investors considering Sydney or Melbourne acquisitions: model rental income conservatively. Use a 3–5% haircut on asking rent for re-let pricing. Stress-test cashflow against 4-week vacancy at every lease turnover.
• For investors holding inner-city Melbourne or Canberra apartments: be ready for a slower re-let cycle. Days on market for re-leases will likely extend by 1–2 weeks compared to 2024.
• For SMSF investors: the window is open. The combination of structural tax advantage, tight rental supply in SMSF-friendly cities, and current lender appetite is favourable.
