Completed 1999 : national renumbering

Australia completed its national telephone numbering plan restructuring for geographic numbers. There were changes expected to be completed for certain services such as operator, calling card and satellite. All geographic telephone numbers in Australia are now a standard single-digit area code followed by an 8-digit subscriber number.

Geoff Dyer has information on Australian 8-digit numbering (website as of June 2004).

The Telecommunications Numbering Plan 1997 took effect 31 December 1997 under the auspices of the Australian Communications Authority (now ACMA).

For other details, see:
