Australia Phone Number Format — How Australian Numbers Work
Australian phone numbers follow a consistent structure managed by the Australian Communications and Media Authority (ACMA). Landlines use a 2-digit area code plus 8 local digits, while mobile numbers start with 04 and are 10 digits total. This guide covers every number type, area codes, international dialing, and example numbers.
Australian Number Structure
All Australian phone numbers consist of 10 digits when dialed domestically (including the leading 0). The first digit after 0 indicates the number type:
Australia's country code is +61. When converting to international format, drop the leading 0 and prepend +61.
Area Codes
Australia has four geographic area codes. Each covers one or more states and territories:
| Area Code | States / Territories | Major Cities |
|---|---|---|
02 |
New South Wales (NSW), Australian Capital Territory (ACT) | Sydney, Canberra, Newcastle, Wollongong |
03 |
Victoria (VIC), Tasmania (TAS) | Melbourne, Geelong, Hobart, Launceston |
07 |
Queensland (QLD) | Brisbane, Gold Coast, Cairns, Townsville |
08 |
Western Australia (WA), South Australia (SA), Northern Territory (NT) | Perth, Adelaide, Darwin, Alice Springs |
Mobile Numbers
Australian mobile numbers start with 04 and are 10 digits long. The format is 04XX XXX XXX. Unlike landlines, mobile numbers are not tied to a geographic area — they work nationwide.
Common mobile prefixes include:
| Prefix | Network (Original Allocation) | Example |
|---|---|---|
0400-0409 | Telstra | 0400 123 456 |
0410-0419 | Telstra | 0412 345 678 |
0420-0429 | Optus | 0421 234 567 |
0430-0439 | Vodafone | 0432 109 876 |
0450-0459 | Various MVNOs | 0451 234 567 |
0470-0479 | Newer allocations | 0478 901 234 |
0490-0499 | Newer allocations | 0491 570 006 |
1300 and 1800 Numbers
Australia has two types of non-geographic service numbers:
| Prefix | Type | Caller Cost | Format |
|---|---|---|---|
1300 |
Local rate | Cost of a local call (from landline); may incur charges from mobile | 1300 XXX XXX (10 digits) |
1800 |
Freephone | Free from all Australian phones | 1800 XXX XXX (10 digits) |
13 |
Local rate (short) | Same as 1300 | 13 XX XX (6 digits) |
Important: 1300 and 1800 numbers cannot be dialed from outside Australia. International callers must use a direct geographic or mobile number instead.
International Format (+61)
To call an Australian number from overseas:
- Drop the leading 0 from the Australian number
