Suburb boundaryFigures are for the suburb boundary shown (ABS 'Suburbs and Localities'). Some sites report a larger statistical area with the same name.Learn more
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For a complete picture, consider both boundary types where available.

Common questions about this page
How do Diddillibah suburb boundaries differ from Statistical Areas?
This page uses Suburbs and Localities (SAL) boundaries (suburb-style geography). SAL represents commonly-known suburb names used in addresses, while Statistical Areas (SA2) are designed for census and statistical reporting. Even when sharing the same name, SAL and SA2 boundaries often cover different geographic areas with different populations.
Where does the data on this Diddillibah page come from?
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.
Is the Diddillibah data on this page just from the 2021 Census?
No. Most of this page is built beyond the Census. Dated for this area: population (Aug 2026), age profile (Aug 2026), infrastructure projects (Aug 2025) and income (FY 2024). Compiled with this profile from sources that publish on their own cycles: development and approvals, property sales and rents, employment, education, transport, health and services and amenities. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
