Suburbs and Localities (SAL)
The ABS's approximation of officially recognised suburbs and localities, built from mesh blocks. It replaced State Suburbs (SSC) from the 2021 Census.
What a SAL is
Suburbs and Localities are the ABS's version of the place names people actually use: suburbs in cities and larger towns, and localities elsewhere. The official boundaries are set by state and territory governments, and the ABS rebuilds them from mesh blocks so Census figures can be published for each one.
There are 15,377 SALs in the 2026 boundaries, covering the whole country. They replaced State Suburbs (SSC) from the 2021 Census, so older data and tools may still use the SSC name and codes.
Suburbs, postcodes, councils and SA2s
Suburbs are the easiest boundaries to talk about, but they line up with very little else.
- Postcodes often cover several suburbs, and some suburbs are split across postcodes, so postcode and suburb figures aren't interchangeable.
- Councils don't contain suburbs neatly. The ABS treats the two as unconnected sets of boundaries, and some suburbs sit across two councils.
- SA2s sometimes match a suburb, but often group small suburbs together or split large ones.
Names
Where the same suburb name exists in more than one state, the ABS adds the state to keep names unique, as in Richmond (Vic.). Censible shows the state alongside the name instead, so you'll see Richmond with Victoria beside it.
Things to watch with suburb figures
- Small suburbs are noisy. The ABS slightly adjusts small counts to protect privacy, so in a suburb of a few hundred people a figure can move noticeably from that alone.
- Boundaries are approximate. Because they're built from mesh blocks, a SAL's edges can differ from the official boundary, and a few official localities don't appear at all.
- Mostly Census only. Most ABS data between Censuses, like annual population estimates, comes by SA2 or council rather than by suburb.
- Sizes vary enormously. Some suburbs have tens of thousands of residents and some have almost none, so comparing suburbs directly can mislead.
Suburbs in Censible
Censible uses the 2026 suburb boundaries. Search a suburb by name, see its figures against Australia and compare it with any other area. When a suburb is too small or too big for the question, an SA2 or a catchment around a point is usually the better unit.

Statistical Area Level 2 (SA2)
A medium-sized area defined by the ABS to represent a community that interacts socially and economically. Most have between 3,000 and 25,000 residents.
Local Government Area (LGA)
LGA stands for Local Government Area: the area a local council looks after. In ABS data, LGAs are the ABS's version of council boundaries, built from small mesh blocks so Census figures can be published for every council in Australia.
Postal Area (POA)
The ABS's version of a postcode, built from mesh blocks so Census figures can be published by postcode. Postal Areas only cover postcodes where people live, so PO box and business-only postcodes aren't included.
Mesh block
The smallest area in the ABS's boundaries, designed where possible to hold 30 to 60 dwellings and tagged with a broad land use. The ABS releases only population and dwelling counts for mesh blocks, and builds every larger area, including councils, suburbs and postcodes, from them.
Perturbation (small-cell adjustment)
The small random adjustments the ABS makes to Census counts so that no individual can be identified. The ABS calls it introduced random error. It barely affects large counts, though it can distort very small ones, and it means table totals may not equal the sum of their parts.
Questions people ask
Suburbs and Localities: the ABS's approximation of official suburb and locality boundaries, used for Census data since 2021.
State Suburbs (SSC) were the ABS suburb boundaries up to the 2016 Census. Suburbs and Localities (SAL) replaced them from 2021. The codes differ, so match on names with care when joining older data to newer data.
No. A postcode often covers several suburbs, and some suburbs are split between postcodes. The ABS publishes separate figures for each, as SALs and postal areas (POAs).
There are 15,377 in the 2026 boundaries, up slightly from 15,353 in 2021.
