Orite has been involving in quite few projects that requires the Australian postcode database, and some even requires Geocoding (GPS coordinates) for mapping purpose. So we have written code to read data from the official AusPost Postcode Datafile and use GoogleMap API to find the coordinates and save to a csv file with 5 fields consists the suburb name, state, postcode, latitude, longtitude. We have recently updated this database accroding to the 12 Jan 2009 datafile released by AusPost, which are available for download in 7Zip compressed file, Australian Postcodes with Geocoding (183KB) If you found anything incorrect in this datafile, please post to let us know.
