Australian area codes and mobile prefixes
Australia needs just four geographic area codes: 02 for NSW and the ACT, 03 for Victoria and Tasmania, 07 for Queensland and 08 for SA, WA and the NT. Mobiles all start with 04 wherever you are, and the business families 13, 1300 and 1800 have no geography at all. The ACMA register lists 73,631 landline blocks under the four area codes, tied to town-level numbering areas.
