How it compares
Household income / wk1st percentile
<$874ABS Census 2021$4,750
Percentiles rank this suburb against Australian Capital Territory 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 Australian Capital Territory and nationally, not a household-weighted median.

Shares are the proportion of the suburb's land area; where part of a suburb is unmapped, only its mapped land counts, so the share is a floor. 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. The ACT has no open flood planning overlay; this is the ACT Government's modelled 1% AEP flood extent, a model of one flood event rather than a planning control. Land outside the modelled urban catchments is shown as no statutory layer. Designated for development control; a designation, not a prediction of fire behaviour. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled.

Planning instruments: Territory Plan; National Capital Plan. Zones are grouped into ten families so states compare; the council's own scheme is the authority for any one lot. Listed-place counts follow each state's own list, so they do not compare across states. Source: ACT Territory Plan zones; ACT Heritage Register.
