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.

Households for the family mix, residents aged 15+ for work, education and income; unemployment is a share of the labour force. NSW 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; 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 the councils that lodged a flood map in their planning instrument are covered; everywhere else is shown as no statutory layer, not as 0%. NSW councils have owned flood-map currency since July 2021, so the state layer may be older than a council's own study. 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: Wollongong Local Environmental Plan 2009; State Environmental Planning Policy (Precincts—Regional) 2021. Zones are grouped into ten families so states compare; the council's own scheme is the authority for any one lot. Height, floor space ratio and lot size are the NSW Local Environmental Plan standards: the area-weighted median over the residential-zoned land where the LEP maps that standard, given only where it maps it on at least half of that land; clause-based exceptions are not modelled. Listed-place counts follow each state's own list, so they do not compare across states. Source: NSW EPI Land Zoning; NSW EPI Heritage; NSW EPI Height of Buildings, Floor Space Ratio and Lot Size.

Percentile is the population-weighted rank among suburbs in the same state — higher means more reported crime. Ranks are never compared across states, because each police force counts offences under its own rules.
