House Numbering - Australia and New Zealand

Australia and New Zealand

In Australia and New Zealand, the current standard (Australia / New Zealand joint standard AS/NZS 4819:2003) for numbering newly created streets is to assign odd numbers to sites on the left and even numbers to the right when facing in the direction of increasing numbers (the European system). This standard came into force in 2003. Some exceptions exist where the road forms part of the boundary between different council areas or cities. For example, Underwood Road in Rochedale South has non-standard numbering, as it forms part of the boundary between Logan City and the city of Brisbane.

In New South Wales, the vast majority of streets were numbered before 2003 with odd numbers assigned to houses on the right of the street when facing in the direction of increasing numbers, and there is no plan to re-assign these numbers.

On some urban roads (e.g. Parramatta Road in Sydney) numbers will typically ascend until the road crosses a council or suburb boundary, then commence again at 1 or 2. Long roads can thus have several occurrences of each number. In semi-rural and rural areas, where houses and farms are widely spaced, a numbering system based on tens of metres or (less commonly) metres has been devised. Thus a farm 2300m from the start of the road, on the right-hand side would be numbered 230.
