Reading the REIA Real Estate Market Facts: what the quarterly REIA prices tell you that CoreLogic doesn't

The REIA Real Estate Market Facts is the oldest national price series in Australia, published quarterly since 1980. Most readers under 40 have never opened it, because CoreLogic's monthly index and PropTrack's daily index have crowded it out of the news cycle. The REIA still matters, and the reason it still matters is what it captures that the others don't: median prices from settled sales reported by actual selling agents, not algorithmic estimates.

The Real Estate Institute of Australia is the peak body for the eight state and territory institutes (REINSW, REIV, REIQ, REIWA, REIT, REISA, REIACT, REINT). Each member institute collects sales reports from its practitioners. REIA aggregates the lot into a quarterly publication covering every capital city, with companion rents, vacancy estimates, sales volumes, and time-on- market figures. The publication is old, slow, and unfashionable, and on certain questions it remains the cleanest source available.

What the quarterly release contains

Each issue covers a single completed quarter and includes a consistent set of tables.

• Median house and unit prices for each capital: Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Darwin, and Canberra. Separate medians for houses and units, with the previous quarter and the year-ago figure for comparison.
• Median weekly rents for three-bedroom houses and two-bedroom other dwellings, by capital.
• Rental vacancy estimates for each capital, drawn from member-institute panels.
• Sales volumes for the quarter by city, with a year-on-year comparison.
• Time on market or time to sell, expressed in days, where the member institute supplies it.

The methodology in plain terms

REIA is a reporter, not a modeller. Five points cover most of what a reader needs to know about how the numbers are built.

• Source: member-institute reporting. Each state's REI gathers sales data from its member agents and aggregates by capital city.
• Filter: residential sales only. Off-market transactions, related-party transfers, and sales under a low-dollar threshold are excluded.
• Reporting lag: typically six to ten weeks after quarter-end, depending on how quickly state settlement data flows in.
• Median, not mean: the headline figure is the median price for the quarter. Less sensitive than a mean to a single $50M Toorak mansion at one end, or a sub-$200k regional sale at the other.
• Unsmoothed: there is no hedonic model, no constant-quality adjustment, no repeat-sales filter. The number is what actually settled, reported as it came in.

Why it differs from CoreLogic and PropTrack

REIA, CoreLogic, and PropTrack are often quoted in the same paragraph, but they are measuring three different things.

• CoreLogic Home Value Index: a hedonic model. It estimates the price of a constant-quality dwelling at a given date by controlling for the attributes of what actually transacted. Smooths out compositional swing. Monthly publication, daily for the HVI.
• PropTrack Home Price Index: a similar hedonic approach using sales and valuation data. Daily for the headline series, monthly for the detailed breakdowns.
• REIA: a pure unsmoothed median of actual settled sales reported via the agent network. Captures compositional drift, and reflects real transaction prices rather than a model of one.

The companion guides on reading the CoreLogic Home Value Index and the PropTrack Home Price Index cover the hedonic side in detail. The short version is that the two algorithmic indexes try to answer the same question ("what is the value of a typical dwelling today?") by removing mix effects, while REIA answers a different question ("what was the median price of what actually changed hands last quarter?"). Both answers are useful. They are not interchangeable.

Where the REIA data leads or lags

Settlement-based reporting has consequences. A buyer who signed a contract in February and settled in April appears in the Q2 release. The Q2 release itself is published around August. CoreLogic, by contrast, uses a contract-date proxy and updates daily. The REIA series is structurally older than the hedonic indexes by four to eight weeks on average, sometimes more.

Compositional sensitivity is the second consequence. The median moves when the mix of sales moves, not only when prices move. A quarter with fewer first-home buyer transactions and more investor purchases at the upper end of the market can push the median up 2 to 4% without any underlying price growth. The reverse happens when a first-home buyer scheme expands and the bottom of the market thickens.

Sample noise is the third. Sydney and Melbourne report thousands of sales a quarter, so the median is stable. Hobart, Darwin, and Canberra report far fewer. A quarter-to-quarter move of 5% in the Darwin median is often a sampling artefact rather than a market signal. Read small-city moves over a rolling four-quarter window rather than a single print.

When to read REIA specifically

REIA is the right tool for a narrower set of questions than the daily indexes are.

• For historical context: the longest unbroken national price series in Australia. Anyone comparing 1985 to 2025 is implicitly relying on REIA, because the alternatives do not reach back that far.
• For cross-checking: if REIA, CoreLogic, and PropTrack agree on direction, the signal is robust. If they diverge, treat all three as noise and wait a quarter. The ABS Residential Property Price Indexes (Cat. 6432.0) sit above all three as the official statistical benchmark; if a quarter's REIA print conflicts with the next ABS release, ABS is the higher authority.
• For rent and vacancy reporting: REIA aggregates state-institute panel data that is hard to assemble elsewhere outside the SQM Research vacancy series. The SQM vacancy guide covers the other major panel; the two can be read alongside each other.
• For time-to-sell trends: a clean indicator of market temperature. Days-on-market shortens in tight markets and lengthens when supply builds.

Common reading errors

Four traps catch most casual readers of the REIA release.

• Comparing the REIA Sydney median to the CoreLogic Sydney HVI as if they were the same number. They are measuring different things: a median sale price for the quarter versus a constant-quality value at a point in time.
• Reading quarter-to-quarter changes in Hobart, Darwin, and Canberra as signal rather than sample noise. The small-city sample sizes do not support that interpretation.
• Ignoring the settlement lag. By the time the Q2 release lands in August, the contracts behind it were signed April through June, and the market has often moved since.
• Treating the REIA median as the "real" price. It is the median of what settled, not the price paid by the typical buyer. Compositional drift sits between the two figures.

A worked numeric example

Suppose the Q3 release reports the Sydney median house price at $1,510,000, up 3.2% on Q2. The CoreLogic HVI for the same period shows +1.8% QoQ. PropTrack reports +1.6% QoQ. Three indexes, one direction, three different magnitudes.

The REIA print is running hot relative to the hedonic pair. The most likely explanation is compositional: the settlements closing in Q3 trace back to contracts signed in Q2, when the market was rising and high-end transactions made up a larger share of the mix. CoreLogic and PropTrack control for that; REIA does not.

A buyer's takeaway: do not anchor on $1,510,000 as "the price". CoreLogic's smoothed +1.8% applied to the prior-quarter level of around $1,455,000 implies a constant-quality value closer to $1,481,000. The REIA median and the hedonic-implied value differ by about $29,000, or roughly 2% of the headline. That is the size of the compositional wedge in a single quarter of a rising market.

Yield math at the two anchor prices is worth running. Assume the same property would let for $625 a week. Annual rent is $625 x 52 = $32,500. Gross yield against the REIA median of $1,510,000 is $32,500 / $1,510,000 = 2.15%. Against the CoreLogic-implied $1,481,000, gross yield is $32,500 / $1,481,000 = 2.19%. The gap is four basis points. Small in isolation, real over a 25-year hold once compounded against finance costs and opportunity cost. Run the same arithmetic against your own property on the rental yield calculator, and against a financed scenario on the mortgage calculator; the lesson is that the headline median is one anchor, not the only one, and the choice of anchor changes the decision.

Reading REIA alongside the rest of the calendar

The quarterly REIA release sits in a stack of property data. The hedonic indexes update daily and monthly; ABS publishes the official benchmark quarterly with its own methodology; the CoreLogic monthly Housing Chart Pack and the Pain and Gain report give context on resale outcomes and seller behaviour. The monthly listings volume read captures the supply side that REIA's time-on-market column is downstream of. For the rent side of the inflation lens, the ABS CPI housing component guide explains how official rent inflation is measured. The broader frame for where the cycle is heading is covered in the 2026 outlook piece.

On Burbfinder, suburb and region pages surface medians, rents, and vacancy alongside the structural drivers that sit underneath them. The REIA release is a useful input when read for what it is: a settlement-based, unsmoothed median from the agent network, six to ten weeks behind the contract market, sensitive to mix, and the longest continuous record this country has. Read it that way and it carries information the daily indexes cannot give you. Read it as a substitute for the hedonic series and it will mislead.
