List of postal codes in Australia
Postcodes were introduced in
Australia in
1967 by the Postmaster-General's Department (PMG), the predecessor of
Australia Post.
Australian postcodes are routing information, and while they are often associated with a single bounded geographical area (e.g. suburb or town) they are not always contiguous areas. They sometimes have quite complex geography, especially in areas beyond the urban fringe (e.g. the southern
Queensland 4352 postcode). Some postcodes cover large populations (e.g., postcode 4350 serving some 100,000 people in the City of
Toowoomba).
Australian Postcodes are four digits long, and written after the name of the city, suburb, or town, and the state or territory:
400 Kent Street:Sydney NSW 2000 :Australia
Although the first digit of the post code indicates the state or territory, an abbreviation is also used:
This does not apply to Australia's External Territories of
Norfolk Island,
Christmas Island,
Cocos (Keeling) Islands:
Norfolk Island 2899
Christmas Island 6798
Cocos (Keeling) Islands 6799
Each state or territory's capital has two separate post codes, for street addresses (ending with the digits '00') and PO Box addresses (ending with the digits '01'):
In the late 1990s, new post code ranges were introduced for PO Box and large users in the following cities:
Although postcode areas in Australia are supposed to correspond with state and territory boundaries, there are many exceptions as of 22 September 2005 (taken by querying Australia Post's own public database):
| Postcode | Suburb | State Derived from Postcode Ranges | Actual State for this Suburb |
|---|
| 0872 | ERNABELLA | NT | SA |
| 0872 | FREGON | NT | SA |
| 2540 | HMAS CRESWELL | NSW | ACT |
| 2540 | JERVIS BAY | NSW | ACT |
| 2611 | BRINDABELLA | ACT | NSW |
| 2611 | URIARRA | ACT | NSW |
| 2620 | HUME | NSW | ACT |
| 2620 | THARWA | NSW | ACT |
| 3500 | PARINGI | VIC | NSW |
| 3644 | BAROOGA | VIC | NSW |
| 3707 | BRINGENBRONG | VIC | NSW |
Some or all of the postcodes above may span two states. For example postcode 2620 covers both a suburb in NSW (
Gundaroo) as well as a suburb in the ACT (
Hume) - the postcode is within the ACT range.
Jervis Bay, an
enclave of the ACT, is geographically located on the coast of NSW, just south of the towns of Vincentia and Huskisson, which accounts for it having a NSW postcode.
