SPECIAL PURPOSE CODES
PURPOSE
Special purpose codes allow address data to be coded to a non-spatial value. This occurs where there is insufficient information to code to a physical geographic area. For example, where someone is in transit on Census night or where an incomplete address has been supplied. They have been created for each hierarchical level within the Main Structure and the Greater Capital City Statistical Area (GCCSA) Structure.
TYPES OF SPECIAL PURPOSE CODES
Migratory
Migratory is used to code people who are in transit on long distance trains, buses, aircraft and long haul road transport vehicles on Census night.
Offshore
Offshore is used to code people on oil rigs and drilling platforms etc. It is also used for expeditioners in the Australian Antarctic Territory.
Shipping
Shipping is used to code people who are on board vessels in Australian waters, in or between Australian ports on Census night.
No Usual Address
No Usual Address is used to code people with no fixed place of abode.

The following examples show the special code structure for New South Wales.
