WA Local Government Authority
The extents of Local Government Authorities are determined by technical description and are published in the Government Gazette. Redescription or partial redescription can be gazetted at any time, but changes between LGA have generally come into effect on the 1st of July following the gazettal. If the LGA change does not affect another LGA, the change can, and generally does take place at the time of publication of the change.
Amendments/changes to the SCDB are formalised at the time specified in the gazettal notice.LGA boundaries do coincide with ward boundaries (where ward systems exist). LGA’s often, but do not have to, coincide with Postal Localities as they are datasets that are independent of one another.
