Australian Postcodes with Geocoding (updated 12 Jan 2009)

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.

    Thanks for your geocoded postcodes. The coordinates of the following are out of range and should be corrected to:

    5238,WALL FLAT,SA,-34.95,139.316667

    (Coordinates obtained from

    Also, I believe the coordinates of the Antarctic bases should be as follows:

    7151,MACQUARIE ISLAND,TAS,-54.5,158.95

    You can check the coordinates of these stations at the Antarctic web site:

    Thanks again,

        Hi Frank,

        Thanks for this useful list. Do you have an updated copy? I am using it to calculate distances to weather monitoring stations from each suburb, and I noticed (by chance) that the odd suburb is missing (e.g. Syndal in Vic).
