SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (for example census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb or locality names (postal-style areas) and may use different geographic boundaries. For a complete picture, consider both boundary types where available.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (115011553). QuickStats reports 2021 only; the figures on this page are more current wherever the ledger shows a later date.
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (for example census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
AreaSearch compiles this page from official and industry sources, including ABS, Geoscience Australia, GNAF, ATO, State governments, Valuer General, Rental Board and Infrastructure Australia, then calculates statistics for the boundary shown, and ranks, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments. Infrastructure projects and development applications also include sites in the surrounding area, labelled as such.
