Median house price

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. 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. Most of this suburb lies in a council whose planning scheme maps no flood-prone areas, or that is still on an interim scheme (Kingborough). Kingborough is still on an interim planning scheme, which this layer does not include. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled.
