General Practitioner Catchment (GPC): Developed by the Australian Government Department of Health and Aged Care, GPCs are custom geographic aggregations based on ABS ASGS 2021 boundaries (SA1, SA2, SA3, UCL). These catchments offer a more accurate representation of where patients access GP services, supporting health service planning and analysis. Statistical Area Level 1 (SA1): SA1s are the smallest units in the ASGS, designed for detailed Census data. Built from Mesh Blocks, they aggregate into larger statistical areas and support urban and Indigenous classifications. Australia has 61,845 SA1s, including special codes for people without fixed addresses.
