Australia's School Zones, Measured: From 0.4 km² to Nearly the Size of Tasmania
How big is the zone your house sits in? We measured every official government school zone published in NSW, VIC, QLD and SA — 5,038 polygons — using proper geodesic areas. The city–country gap is staggering: Parramatta HS (NSW) draws from just 0.4 km², while Willyama HS in outback NSW covers 59,248 km² — about 148,000 times larger, and 87% the size of Tasmania.

The 15 smallest secondary zones in Australia

Outback zones are astonishingly vast — for some students the "local" school is hundreds of kilometres away.
State by state (secondary zones)
Median zone sizes differ six-fold: Victoria draws the tightest boundaries, Queensland the widest.

Methodology
Boundaries are the most recent published by each state education department (VIC and QLD: 2026 school year; SA: 2023; NSW: current published dataset). Areas are computed with spherical geometry (spherical excess), immune to the latitude distortion of flat-map methods; multi-part zones are summed, holes subtracted, and 0.05 km² digitisation slivers (2 polygons) excluded. WA, TAS, NT and the ACT do not publish machine-readable zone data and are not covered. Licensed CC BY 4.0 — cite AroundSchools and reuse freely.
