What data is expected?

A database of postcodes/zipcodes and the corresponding spatial locations in terms of a latitude and a longitude (or similar coordinates in an openly published coordinate system). The data has to be available for the entire country. See our methodology section for more information.

  • Zipcodes
  • Addresses
  • Coordinates (latitude, longitude)
  • Data available for entire country

How open is the data?

GNAF is the national geocoded address file, and as such, it fulfills the requirements as it gives coordinates for all addresses including their postcodes, which is more accurate than postcode centroids or polygons. There are non-free versions of postcode boundaries ( and centroids ( The ABS also freely publishes approximations of postcode boundaries to coincide with the 5-yearly Census release

I thank dearly to Toby Bellwood for his attention and help with this review.
