Australia Postcode Finder
Last Updated: 1 Sep 2026
Find Australian postcodes by suburb, city, or state, and understand how postcode information is used when planning where to study, live, work, rent, or settle in Australia.
Australian postcodes are used every day for addresses, deliveries, campus locations, rental searches, job applications, and government forms. For international students and migrants, the right postcode can also help when comparing suburbs, campuses, workplaces, and regional locations.
Quick Answer
An Australian postcode is a four-digit code used to identify suburbs, towns, delivery areas, and post office box areas. For example, Sydney CBD uses 2000, Melbourne CBD uses 3000, Brisbane CBD uses 4000, Adelaide CBD uses 5000, Perth CBD uses 6000, Hobart CBD uses 7000, Darwin uses 0800, and Canberra uses 2600.
Find an Australian Postcode by Suburb, City, or State
You can search Australian postcodes by suburb, city, state, or postcode number. If you are checking an address, make sure the suburb, state, and postcode match correctly.
A single postcode can cover more than one suburb. Some suburbs may also have different postcodes depending on the delivery type, such as street delivery or post office boxes.

Why Postcodes Matter for Students and Migrants
A postcode may look like a small detail, but it can affect many practical parts of life in Australia.

comparing city, suburban, and regional locations
For international students, a postcode can help when comparing where to live near a campus, checking commute distance, searching for nearby work opportunities, or understanding whether a suburb is close to the services they need.
For migrants and skilled workers, postcode information can also help when comparing job locations, employer addresses, rental areas, and long-term settlement options. If your location choice is connected to a future visa strategy, you can also explore RACC Australia’s migration services.
Are Postcodes Used for Migration or Regional Visa Planning?
Sometimes, yes. For some visa and migration purposes, the Department of Home Affairs publishes official postcode lists for designated regional areas.
However, a general postcode search should not be treated as visa advice. A postcode alone does not confirm whether you are eligible for a visa, regional pathway, graduate visa benefit, nomination, sponsorship, or permanent residency pathway. If you need personalised guidance, you can book a consultation with RACC Australia.
Important: If your study or migration plan depends on whether an area is considered regional, always check the official Department of Home Affairs guidance or speak with a Registered Migration Agent.
