No dataset covers everything. These matter to the decision and we don't hold them — here's where to look.
Days on market
How fast stock clears is a leading indicator — it moves before prices do. We have no free suburb-level source for it.
Count active listings on realestate.com.au or Domain and check their listing dates, or ask two local agents.
Auction clearance
Buyer competition at the margin. Only meaningful where auctions are actually common — in outer and regional suburbs most sales are private treaty, so a clearance rate says little.
Your state's Real Estate Institute publishes weekly clearance rates by region.
Flood risk
Drives insurance cost and, increasingly, insurability — which caps the resale pool. No free national dataset exists at suburb level; it is mapped council by council.
Search your council's flood overlay or planning portal for the specific address — risk varies street by street, so a suburb-wide rating would mislead even if we had one.
Bushfire risk
Same insurance exposure, plus rebuild-standard costs inside designated zones.
Check your state's designated bushfire-prone area mapping — NSW Planning Portal, VIC's BPA layer on VicPlan, Queensland Globe, or WA's Map Viewer Plus.
Strata and body corporate costs
For units this can swallow a third of gross rent, and a special levy can arrive without warning.
Ask for the strata report and the last two years of minutes before you offer.
What the street is actually like
Suburb medians average over streets that trade very differently — a main road, a flight path or a commission block will not show up in any of the figures above.
Walk it at night and on a weekday morning. Nothing on this page substitutes for that.
AI insights for St Clair
Investment analysis, risks & comparisons
St Clair shows strong investment fundamentals with above-average rental demand and a tightening supply pipeline. The gentrification index of 67/100 signals continued capital appreciation potential, particularly within 600m of the main retail and transit corridor.
Key risk: elevated auction clearance volatility over the past two quarters suggests shifting buyer sentiment. Net yield after typical holding costs sits at approximately 3.6%, below the state median of 4.1% — factor this into cash-flow modelling.
