This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
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 comprehensive analysis, consider reviewing both boundary types if available.
