How it compares
Household income / wk50th percentile
<$450ABS Census 2021$2,750+
Percentiles rank this suburb against Tasmania 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 Tasmania 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. A statutory planning-control boundary, not a flood extent, and it can lag the latest flood study. Only councils whose Local Provisions Schedule maps flood-prone areas are covered. Designated for development control; a designation, not a prediction of fire behaviour. Kingborough is still on an interim planning scheme and is shown as no statutory layer. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled.
