How it compares
Household income / wk19th percentile
<$564ABS Census 2021$3,833+
Percentiles rank this suburb against New South Wales 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 New South Wales 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. No flood map lodged in the NSW planning instruments for most of this suburb; most councils keep theirs in a development control plan. 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: Greater Taree Local Environmental Plan 2010; Gloucester Local Environmental Plan 2010. 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: NSW EPI Land Zoning; NSW EPI Heritage.
