Methodology

Where the list comes from

We read the OpenStreetMap extracts for each state and territory (Geofabrik, snapshot 9 Nov 2026) and keep every amenity=parking point, area and multipolygon. The same object appearing in two state extracts is kept once.

Which car parks are listed

• Not listed: access=private or access=no; customers, permit, destination and similar user-only car parks; points that duplicate a mapped car-park area; individual parking bays (amenity=parking_space).
• Listed: access recorded as public (yes, permissive) and car parks with no access tag (“Access not recorded”).

Areas

Each location is placed in an ABS ASGS Edition 4 (2026) state, council area (LGA) and suburb/locality (SAL) by point-in-polygon. LGA and SAL are matched separately; a suburb can span councils. Points on the edge of the data or outside the eight states and territories are not listed.

Which areas get their own page

An area gets its own guide when it has at least 10 listed car parks and at least two details recorded on 20% or more of them. Smaller areas appear as sections of the larger guide. These thresholds are provisional.

Unknown is not no

When a detail is not recorded we say “Not recorded”. We never turn a blank into “no charge”, “public”, “no fence” or “no shade”.
