What You'll Learn

Postal address format
When writing a postal address in Australia, there are a few things to keep in mind. Firstly, the format is similar to that of the US, with the city, state, and postcode appearing on the same line.
The address should be written clearly, preferably using a black or blue pen, and without any indentation, staggered lines, underlining, or punctuation. A clear and readable font type, such as Helvetica, Arial, or Times Roman, is recommended.
[Recipient's name]
[Traditional Place name (optional)]
[Unit number]/ [Street address]
[Suburb/locality], [state] [postcode]
For example:
John Smith
U 2/98 Shirley Street
Brisbane, QLD 4000
If you are sending mail to a PO Box in Australia, you only need to include the PO Box number, city, state, and postal code. A street address is not necessary. For example:
John Smith
PO Box 1234
Brisbane, QLD 4000

Flat/unit number placement
When writing an Australian address, the placement of the unit number can vary. While Australia Post's Addressing Guidelines do not mention how to indicate unit numbers, there are a few commonly accepted formats.
One way to write the unit number is to place it before the street number, separated by a forward slash. For example, "Unit 6a/100 Main Street" or "6a/100 Main Street". The unit number can also be written on a separate line before the street address, as in "Unit 6a" on one line, and "100 Main Street" on the next line.
Another format is to use the abbreviation "U" followed by the unit number and then the street name, with two spaces between the unit number and the street number. For example, "U 2 17 Jones St". Alternatively, the "U" can be omitted, resulting in "2/17 Jones St".
It is important to include all essential details in an address, such as the name, street address, apartment or unit number, city, state, and postcode. When mailing internationally, it is crucial to follow the specific addressing format of the destination country to ensure the mail reaches its intended recipient without delays or errors.

Australia Post's addressing guidelines
The first line of an address should contain the recipient's name. If you are sending mail to a business, the business name should be on the first line, and the recipient's name should be on the second line. The second line should also include the street number and name, or PO Box or Locked Bag number.
The third line should include the locality or suburb, state, and postcode, written in capital letters. For international mail, the country name should be written in capitals on the bottom line.
For machine-addressed envelopes, use a clear, readable font such as Helvetica, Arial, or Times Roman. Check that the locality or suburb matches the postcode using the 'find a postcode' tool. The postcode should be included on the same line as the locality or suburb and state, with spaces left between the locality, state, and postcode.
To acknowledge the Traditional Custodians of the land, you can include Traditional Place Names in the address field. Traditional Place Names can be found by checking with AIATSIS, Aboriginal and Torres Strait Islander Land Councils, or Cultural Centres in your local area. The Traditional Place Name should be included below your name or company name but above the street address.
When it comes to indicating unit numbers, Australia Post's Addressing Guidelines do not mention a specific format. Some sources suggest writing the unit number, followed by a forward slash, and then the street number (e.g., "Unit 6a/100 Main Street"). Alternatively, you can write the unit number on a separate line before the street number and name (e.g., "Unit 6a" on one line, and "100 Main Street" on the next line). Another format suggested is "U 2 17 Jones St" or "2/17 Jones St", with two spaces between the unit number and street number in the latter format.

Format for unit numbers
When writing out postal addresses in Australia, the unit number is typically placed before the street number, with the two numbers separated by a slash. This format is also known as the "unit/street number" or "unit-street number" format. Here are some examples:
- U 2/17 Jones St or 2/17 Jones St (with two spaces between the unit and street number when using the first format)
- 6a/100 Main Street, U6a/100 Main Street, Unit 6a/100 Main Street
- 3/2-4 Imaginary Street
In this format, the number before the slash refers to the unit number, and the number after the slash refers to the street number. This format is commonly used for apartments or flats, where the unit number indicates a specific unit within a building, and the street number identifies the building's location on the street.
It's worth noting that Australia Post's addressing guidelines do not specifically mention how to indicate unit numbers. However, the use of the slash to separate the unit and street numbers is widely accepted and recognised in Australian addressing conventions. Additionally, hyphens in Australian addresses are used to indicate ranged addresses, often referring to housing complexes that span multiple stretches of roads.

PO Box restrictions
PO Boxes in Australia are lockable mailboxes located inside a Post Office. They are used by individuals and businesses to receive mail and parcels. Australia Post offers a range of PO Box sizes and lease times, with annual fees depending on the location.
There are some restrictions and challenges associated with using a PO Box in Australia. Firstly, they are not available to persons residing on houseboats, water or sea vessels, or on private roads such as caravan parks, gated communities, retirement villages, or defence force barracks. Additionally, there may be issues with receiving parcels from third-party carriers, as some couriers may not deliver to PO Boxes, and there may be extra charges for receiving parcels that are too large for the box. There is also a limit of 50 parcels per year, after which there is a $3 charge per parcel.
Another restriction is that PO Boxes can only be used if Australia Post does not deliver mail to the customer's residential or business address. However, this also means that users must physically travel to the Post Office to collect their mail and packages, which may be inconvenient for some.
To apply for a PO Box in Australia, individuals can apply online through their MyPost account or by submitting an application form at a participating Post Office. An application form can be downloaded or obtained from a Post Office. An annual fee applies, which can be paid online or in person.
Overall, while PO Boxes offer benefits such as privacy, security, and a permanent address for mail, there are also some restrictions and challenges that users should be aware of.
