Our data & valuation methodology

Where our suburb data comes from

Australia has no free, live, suburb-level feed of individual sale prices. The Queensland government sale-record extract is paid, and the medians published by CoreLogic/Cotality and Domain are licensed. So our suburb figures are anchored to recently published market data — Domain suburb profiles, Cotality/CoreLogic-derived aggregators, realestate.com.au, PropTrack and REIQ — captured at a stated reference period and attributed on each suburb page.

Because methodology differs between those sources, we treat the numbers as indicative estimates rather than official sale-record medians. That's why suburb pages say a median is "approximately" a figure rather than presenting it as an exact, authoritative number.

How we keep figures current between refreshes

Each anchored median is captured with the month it refers to. Between manual refreshes, we roll that figure forward from its reference month to the current month using the suburb's own growth rate, so the displayed number tracks the market rather than going stale at the date it was captured.

We re-check the underlying sources roughly every quarter and update the anchors. Our build process flags any anchor older than six months so nothing quietly drifts out of date. Where a source publishes a real year-on-year change, we use it; where it doesn't, the change shown is modelled and labelled as such.

Houses vs units, and why we separate them

We prefer a suburb's house median over a blended "dwelling" figure, because dwelling medians mix houses and units together and read artificially low in house-heavy suburbs. House and unit medians are tracked separately so the number you see matches the kind of property you're actually looking at.

How a property valuation is built

When you request a free property report, the estimate is built from recent comparable sales near the address — homes of a similar type, size and condition in the same suburb — rather than from a single citywide average. We layer in the suburb's current median and what's presently on the market to produce a realistic range, not a single false-precision figure.

The inputs you provide — bedrooms, bathrooms, car spaces and the property's condition — adjust that range, because two homes on the same street can be worth very different amounts depending on what's been done to them.

What this is — and isn't

Our estimates are designed to help you make confident decisions: to time a campaign, sense-check a bank valuation, or judge whether a renovation paid off. They are guidance, built from the same kind of sales data agents use.

They are not a formal valuation. An estimate can't inspect your home, account for a recent renovation it doesn't know about, or read the specific buyer competition on auction day. For a decision that turns on an exact figure — a legal or finance valuation — engage a licensed valuer or a local agent who can stand in the property.

Corrections

If a figure looks wrong for a suburb you know well, tell us. We'd rather fix an anchor than leave a number that misleads. Accuracy is the whole point of the site.
