🏙️ Top 25 Most Densely Populated Suburbs in New South Wales
Population density — the number of residents packed into each square kilometre — is one of the clearest signals of how a suburb lives. High-density suburbs are built around apartments, walkable streets, public transport and close-in amenities; low-density suburbs spread out into detached houses, bigger blocks and a reliance on the car. This ranking lists the 25 most densely populated suburbs in New South Wales, calculated from the Australian Bureau of Statistics 2021 Census population divided by each suburb's gazetted land area.
Wentworth Point leads with about 22,131 residents per square kilometre — 12,703 people living across just 0.57 km². That is well ahead of the midpoint of this list (Bondi, ~12,036/km²). The densest suburbs cluster tightly around inner-city apartment precincts and high-rise renewal areas, where former industrial land has been rebuilt into vertical living.
Only suburbs (ABS SAL geographies) with a Census 2021 population of at least 500 residents and a land area above 0.1 km² are included, which keeps the list to genuine residential neighbourhoods and removes tiny localities whose density figures would be statistical noise. Note that area covers the whole gazetted locality — including any parks, water or non-residential land — so the lived density of the built-up core can be even higher than the figure shown.

đź“Š Methodology
Population density is calculated as Census 2021 total population ÷ gazetted land area (km²) for each suburb (ABS SAL geography) in New South Wales. Only suburbs with at least 500 residents and a land area above 0.1 km² are included, to avoid distortion from very small or sparsely populated localities. Ties are broken by total population (larger first). Land area covers the whole locality, including parks, water and non-residential land, so the density of the built-up residential core may be higher than shown.
