Postal Areas (POA)

Postal Areas (POAs) are designed to approximate postcode boundaries, as closely as possible. There is not a one-for-one correspondence between Australia Post postcodes and POAs, but these are a good starting point for comparison of Census data with other data collected using postcodes.

Census Postal Areas exclude non-mappable Australia Post postcodes such as:

• post office box postcodes
• some delivery route postcodes, which are also covered by other postcodes (a situation which often occurs in rural areas)
• some postcodes which, because of the application of the 'best fit' principle, do not get a Mesh Block allocated to them.
