5,000 cities in Australia, ranked by population, as a single downloadable JSON file. No API key, no rate limit, no sign-up — just a static file you can fetch, cache, or commit straight into your own project.

A flat, population-ranked file like this is a good fit for offline builds, seed data for a database, a country/city dropdown that doesn't need live search, or a quick lookup table in a script or notebook. It's a static snapshot, not a live feed — there's no search index, no translations, and no guarantee it reflects changes made to Australia's administrative boundaries after 2026-07-14.
For prefix search, autocomplete, multilingual names, or coordinate-based queries — anything that needs to stay current or searchable — use the API instead of the static file:
curl --request GET \
--url 'https://geomelon.p.rapidapi.com/cities/search?countryCode=au&sort=population_desc&limit=10' \
--header 'x-rapidapi-host: geomelon.p.rapidapi.com' \
