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. 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 & zoning

0.6% of the suburb sits outside any mapped zone (typically unzoned roads, water or land outside the scheme), so the shares add up to 99%.

Planning instrument: Lane Cove Local Environmental Plan 2009. 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.
