This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.
