Australia, subunits are essential and should be separated from the street by two spaces; apartments, flats and units are typically separated with a forward slash (/) instead. Apartment, flat and unit numbers, if necessary, are shown immediately prior to the street number (which might be a range), and, as noted above, are separated from the street number by a forward slash. These conventions can cause confusion. To clarify, 3/17 Adam Street would mean Apartment 3 (before the slash) at 17 Adam Street (in the case of a residential address) or Unit 3 at 17 Adam St (in the case of a business park). On the other hand, 3–17 Adam Street would specify a large building (or cluster of related buildings) occupying the lots spanning street numbers 3 to 17 on one side of Adam St (without specifying any particular place within the buildings). These forms can be combined, so 3/5–9 Eve Street signifies Apartment 3 (before the slash) in a building which spans street numbers 5 to 9 on one side of Eve Street. As in the US, the state/territory is crucial information as many placenames are reused in different states/territories; it is usually separated from the suburb with two spaces and abbreviated.

In addition to PO Boxes, other delivery types (which are typically abbreviated) may include: Australian Post Addressing Guidelines In rural areas, "Property numbers are worked out based on the distance from the start of the road to the entrance of the property. That distance (in metres) is divided by ten. Even numbers are on the right and odd numbers are on the left. For example: the entrance to a property 5,080 metres from the start of the road on the right hand side becomes number 508. The start of the road is determined as the fastest and safest road accessed from the nearest major road or town. Rural road maps are being drawn up to define the name, the start point and direction of every rural road."
