Download Free Database of Australian Postcodes
Last Updated: 1st March 2021
A free, up-to-date downloadable database of Australian Postcodes and Localities, including accurate longitude and latitude values, sourced by and supported by the community.

Some years ago, Australia Post used to publish a full list of Australian Postal Codes including state and location data, in a raw data format, completely free.
They have since stopped doing this, instead preferring to charge for data that is arguably public domain, or at least available publicly in many different forms from many different providers.
I've needed this data for a number of projects over the years, and have collated as much publicly-available postal data as I could find. There are a bunch of files out on the internet with this data, but they are all missing data or detail, so I've tried to collate them as best I can.
You can learn more about Australian Postcodes on Wikipedia.
The database currently contains 18,272 entries, spread over the following states:
|ACT ||Australian Capital Territory ||0200 to 2914 ||159 ||159 ||0 ||145 ||2 ||153 ||153 ||View All |
|NSW ||New South Wales ||1001 to 4385 ||5540 ||5539 ||206 ||4892 ||67 ||5445 ||5445 ||View All |
|NT ||Northern Territory ||0800 to 4825 ||390 ||390 ||0 ||212 ||0 ||378 ||378 ||View All |

1 Many large businesses, government departments and other institutions receiving high volumes of mail had their own postcode as a Large Volume Receiver (LVR), e.g. the Royal Brisbane and Women's Hospital has the postcode 4029, the Australian National University had the postcode 0200. More postcode ranges were made available for LVRs in the 1990s. Australia Post has been progressively discontinuing the LVR programme since 2006.
The files have eight fields in each:
|Primary Key from source database
|The postcode in numerical format - 0000 to 9999
|The locality of the postcode - typically the city/suburb or postal distribution centre
|The Australian state in which the locality is situated
|The longitude of the locality - defaults to 0 when not available
|The latitude of the locality - defaults to 0 when not available
|The Australia Post distribution Centre servicing this postcode - defaults to blank when not available
|The type of locality, such as a delivery area, post office or a "Large Volume Recipient" such as a GPO, defaults to blank when not available
|The SA3 Statistical Area code
|The name of the SA3 Statistical Area
|The SA4 Statistical Area code
|The name of the SA4 Statistical Area
|Designated Regional Area
|A note indicating whether the data is new, removed or updated - new column Nov 2018
Extended Dataset Fields added 2021
|Latitude from Google Maps API|
|Longitude from Google Maps API|
SA1 Maincode 2011
|Statistical Area 1 2011 Code|
SA1 Maincode 2016
|Statistical Area 1 2016 Code|
SA2 Maincode 2016
|Statistical Area 2 2016 Code|
SA2 Name 2016
|Statistical Area 2 2016 Name|
|Remoteness Area - 2011 Dataset|
|Remoteness Area - 2016 Dataset|
|Modified Monash Model - 2016 Dataset|
|Modified Monash Model - 2019 Dataset|
1 These fields are no longer being updated, as the data isn't overly relevant outside of AusPost.

If you'd like any other format, just let me know and I can add it to this page.
Note on Latitudes & Longitudes
As of March 2021, there are now two sets of differing Lat/Long points for each postcode. The first are the points provided in the Australia Post database, and those derived from adjacent postcodes.
The second set, possibly more accurate, are derived from Googles Map API in 2020/2021. As Australia Post do not appear to have updates or added any new Lat/Long values in recent years, it is presumed the Google values are more accurate.
Addition of ABS Statistical Area 3 (SA3) and Statistical Area 4 (SA4) datasets
I've recently added SA3 and SA4 data sets to the postcode database. Nearly all postcodes have these values, however not all, so it can't be considered 100% accurate.
Also, the SA3/SA4 data set is from the 2016 census, so there might be some changes since. If anyone has a more recent database, please let me know!
SA1 datasets were kindly provided by Gary W. in 2021 and have been added to the datasets.
You can learn more about SA3 and SA4 on the ABS site in the 1270.0.55.001 - Australian Statistical Geography Standard (ASGS) section.
Designated Regional Area Postcodes
I've added R1, R2 and R3 region codes based on GOV.AU data and Immigration categorization. It's not 100% accurate, as they exclude many postcodes, but is a good representation nonetheless.

Remoteness Area Designations
The Australian Statistical Geography Standard (ASGS) is a set of geographical data that can be analysed together for different purposes. The data are from the Australian Bureau of Statistics (ABS) and other organisations.
The ASGS determines five levels of remoteness for areas under the Australian Statistical Geography Standard - Remoteness Area (ASGS-RA) structure.

Modified Monash Model
The Modified Monash Model (MMM) is how we define whether a location is a city, rural, remote or very remote.
model measures remoteness and population size on a scale of Modified Monash (MM) category MM 1 to MM 7. MM 1 is a major city and MM 7 is very remote.

There are many, many potential uses for this database. Some of the projects and uses people have downloaded the database for include:
- Having a complete list of current suburbs in Australia
- Calculating distances between two Australian postcodes or two Australian suburbs
- Grouping population and other statistical data by suburb or postcode
- Mapping rainfall data to regions
