QuickProperty mixes release files, Census baselines, and matched local services on this page. Read the status panel before treating every metric as equally fresh.
Official quarterly house sales workbooks; units remain on ABS fallback coverage
Treat the rent field as missing until a market or plausible Census rent value is linked.
Schools, transport, and hospitals are useful as presence signals, but they still have different source cadences.

Small-population localities can still be worth checking, but rankings, comparisons, and broad suburb assumptions become noisier faster.
Coverage is thinner on school matches, hospital coverage, and transport stops; lean less on this one page and confirm those gaps elsewhere.
Check nearby suburbs, the state hub, and rankings for firmer comparables before making this a shortlist decision.
