The Australia country code is +61 — reaching 27 million Aussies across the world's 6th-largest country by area, with ~32 million mobile subscriptions across Telstra, Optus, Vodafone (TPG) + Aussie Broadband. One country, 4 simple area codes, 3 time zones.
Australia was assigned +61 by the ITU in 1949 — sharing ITU zone 6 with most of Oceania + South-East Asia. Here is the simplest country-code area-code scheme in the world.
Australia has used the +61 country code since 1949, when the ITU placed it in zone 6 alongside Indonesia +62, Philippines +63, New Zealand +64, Malaysia +60, Singapore +65, Thailand +66 + Vietnam +84. The "1" suffix was one of the first single-digit slots in zone 6 — making +61 one of the shortest South-Pacific codes.
Australia's telecom industry is regulated by the ACMA (Australian Communications and Media Authority). Three major mobile carriers operate: Telstra (~19M subs, the former state-owned monopoly), Optus (~10M, owned by Singtel), Vodafone Australia / TPG Telecom (~5M). All offer GSM/LTE/5G — Australia deployed 5G in 2019.
Australia uses just 4 geographic area codes, each 1 digit after the leading 0. <b>02</b> covers New South Wales + the Australian Capital Territory (Sydney, Canberra). <b>03</b> covers Victoria + Tasmania (Melbourne, Hobart). <b>07</b> covers Queensland (Brisbane, Gold Coast, Cairns). <b>08</b> covers Western Australia + South Australia + Northern Territory (Perth, Adelaide, Darwin). The 4 zones are the simplest in any major country.
Australia\'s 0011 exit code is unique. Almost every country uses "00" or "011" to dial international — Australia is one of just a handful using 0011. The extra digit is a legacy from Telstra's original Overseas Telecommunications Commission (OTC) routing in 1976. To dial out internationally from Australia: 0011 + country code + number, or just + from any mobile.
An Australian phone number in international format is written as +61 [area] [8-digit local] — for example, +61 2 9374 4000 for a Sydney landline (domestic 02 9374 4000), +61 3 9605 1234 for Melbourne (03 9605 1234), or +61 4 1234 5678 for an Australian mobile (04XX XXX XXX domestic).
Australian mobile numbers always start with 04 domestically — written internationally as +61 4 XXXX XXXX. All Australian mobiles are 10 digits domestically (9 after dropping the leading 0). The "0" across all Australian numbers (02, 03, 07, 08, 04) is the national trunk prefix — dropped when dialing from abroad.
+61 2 9374 4000 reaches Sydney.From the Sydney Opera House to the Perth CBD, every Australian number lives behind a +61. Pick the area code that matches your customer state or territory.
Every country uses a different international exit code before the +61 Australia country code. From any mobile, the + symbol replaces the exit code automatically — so +61 2 9374 4000 works worldwide. Always drop the leading 0 from Australian numbers (02 Sydney → 2, 03 Melbourne → 3, 04 mobile → 4) when dialing from abroad.

Drop the 0 from abroad. The full E.164 format is +61 [area or mobile prefix without 0] [8 digits] — always 11 digits total with +61.
+61 reaches one of the highest mobile-spend-per-capita markets on Earth, the Asia-Pacific's most English-fluent gateway + a 27M-person population with 99.4% mobile penetration.
Australian banks (CommBank, Westpac, ANZ, NAB, Macquarie, Bendigo, ING Australia, Up) + the ATO (Australian Taxation Office) + the myGov portal verify with +61 mobile numbers. Foreign numbers face SMS-throttling.
Many Australian B2B providers (Xero, MYOB, ServiceNow ANZ) treat a +61 contact number as a baseline trust signal for ABN-holding businesses. An AU number unlocks faster onboarding + dispute resolution.
A 02 prefix reads as Sydney CBD + the Macquarie Park tech corridor + Canberra (the ACT). A 03 says Melbourne + Hobart. A 07 says Brisbane + Gold Coast. An 08 says Perth + Adelaide + Darwin. Four prefixes cover 27 million people.
Australia sits in the same business day as Singapore, Hong Kong, Tokyo + much of South-East Asia. A +61 number is the cleanest single contact for any Asia-Pacific regional play.
Eastern Australia (Sydney, Melbourne, Brisbane) runs on AEST (UTC+10) — 1 hour ahead of Tokyo + Seoul. AEDT (UTC+11) in summer. Perth runs on AWST (UTC+8) — aligned with Singapore + Hong Kong. Adelaide + Darwin use the unusual UTC+9:30 / +10:30 (ACST/ACDT).
