EV charging site selection in Western Australia

Western Australia runs at 7.2 chargers per 100 candidate host venues, which is above the 5.0 we measure nationally and ranks it 2nd of the 8 states we cover. Raw charger counts are a poor comparison because they mostly track population; normalising by the venues that could plausibly host a charger is what makes Western Australia and the other states comparable at all.

On unmet demand, 1.5% of the 997 analysis cells we score in Western Australia come out as charging blackspots — places where traffic, population and income all indicate demand and the nearest charger is still out of reach — against 1.3% nationally. That is the more interesting half of the picture: it means there is proportionally more unserved demand here than in most of the country.

Those two facts sit together more often than people expect. High coverage and high unmet demand at the same time means the chargers that exist are concentrated — clustered where they were easy to build rather than spread where they are needed.

Western Australia publishes an open annual average daily traffic (AADT) count dataset, so every score on this page carries a measured traffic term rather than an inferred one. That matters more than it sounds: passing traffic is the single strongest predictor of charger utilisation, and states without it are scored on demographics and venue density alone.

Every Western Australia figure above is computed from ABS census data, OpenStreetMap venue and car-park geometry, Open Charge Map charger locations and WA government traffic counts — the same sources, the same models and the same thresholds used in every other state. The methodology is published in full.
