Percentiles rank this suburb against Victoria suburbs that carry the metric — never across states, and never against suburbs where it is missing. Price references are ABS median established-house transfer prices for the Mar 2026 quarter (CC BY 4.0); the suburb figure is a Valuer-General median over a different window, so read the gap as indicative. Income references are the Census 2021 median of the middle suburb in Victoria and nationally, not a household-weighted median.

Households for the family mix, residents aged 15+ for work, education and income; unemployment is a share of the labour force. VIC figures weight each suburb by its dwellings or residents. ABS Census 2021 (CC BY 4.0). Withheld for very small populations — under 100 residents, or under 50 dwellings, households or workers for the shares that count those.

Shares are the proportion of the suburb's land area. Land where Landsat saw water in at least 1% of clear passes since 1987, excluding permanent water and filtered by DEA's confidence layer. Satellites miss flood peaks, so this is a floor, not a risk estimate; dense high-rise cores can still register tower shadow as water. A statutory planning-control boundary, not a flood extent, and it can lag the latest flood study. Designated for development control; a designation, not a prediction of fire behaviour. The Building Regulations' Designated Bushfire Prone Area, the like-for-like of NSW Bush Fire Prone Land; the narrower Bushfire Management Overlay is a separate planning control. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled.
