Australian Postcodes and Telephone Area Codes
Australian postcodes (zip codes) can cover large areas, suburbs, towns, even multiple towns in regional areas. You might also be interested in our School and Public Holiday dates and Time Zones & Daylight Saving pages.

This system was introduced in 1967.
