+61 Country Code: Australia Dialing Guide

+61 is Australia's country code. When you're calling Australia from overseas, dial +61, drop the leading zero from the Australian number, and dial the rest. A Sydney landline like 02 9876 5432 becomes +61 2 9876 5432 internationally.

That's the short version. Here's everything else you might need.

What is the +61 Country Code?

The +61 country code identifies Australia in the international phone system. Every country has one - the US is +1, the UK is +44, and Australia is +61.

When dialing from abroad, +61 replaces the "0" that Australians use for domestic calls. That leading zero is just a trunk code for calls within Australia. International calls don't need it.

How to Dial Australian Numbers

To call Australia from another country, follow this format:

+61 + area code (no zero) + local number

Here's how it works in practice:

What You Have	What You Dial
Sydney: 02 9876 5432	+61 2 9876 5432
Melbourne: 03 8765 4321	+61 3 8765 4321
Brisbane: 07 3456 7890	+61 7 3456 7890

Notice how the "0" disappears? That's the key. The +61 takes its place.

If you're using a mobile phone, the + symbol usually works directly. On a landline or older phone, you might need your country's exit code first (like 011 from the US), making it 011 61 2 9876 5432.

Australian Area Codes

Australia uses four main area codes, each covering different states and territories:

City/Region	Area Code	International Format
Sydney, NSW	02	+61 2
Melbourne, VIC	03	+61 3
Brisbane, QLD	07	+61 7
Perth, WA	08	+61 8
Adelaide, SA	08	+61 8

Perth and Adelaide share the same area code (08), but they're on opposite sides of the country. The local numbers are different, so there's no confusion.

Calling Australian Mobile Numbers

Australian mobile numbers start with 04, which becomes +61 4 when dialing internationally.

Domestic format: 04XX XXX XXX (10 digits total) International format: +61 4XX XXX XXX (drop the 0)

Example:

In Australia: 0412 345 678
From overseas: +61 412 345 678

Mobile numbers are the same format nationwide - there are no regional mobile codes. If it starts with 04, it's a mobile.

Time Zones: When to Call Australia

Australia is significantly ahead of the US - between 13 and 18 hours depending on which part of Australia and which US time zone.

Sydney and Melbourne (AEST):

15-16 hours ahead of New York (EST)
17-18 hours ahead of Los Angeles (PST)

Perth (AWST):

13-14 hours ahead of New York
15-16 hours ahead of Los Angeles

Practical tip: If it's 6 PM on Monday in New York, it's roughly 9 AM on Tuesday in Sydney. Your Monday evening is their Tuesday morning.

Australia also observes daylight saving time, but in reverse seasons (October to April). The time difference shifts by an hour during these transitions.

Calling the US from Australia

If you're reading this from Australia and need to call the US, the process flips. The US country code is +1, followed by the area code and number.

Example: To call a New York number (212) 555-1234 from Australia, dial +1 212 555 1234.

Australian mobile carriers charge varying rates for calls to the US - anywhere from $0.20 to over $2 per minute depending on your plan.

Frequently Asked Questions

What does the +61 prefix replace when calling Australia?

The +61 replaces the leading 0 used inside Australia for domestic trunk dialing. A Sydney landline saved as 02 9876 5432 in an Australian's phone is the same line that an overseas caller dials as +61 2 9876 5432. The 0 is a national trunk prefix that tells Australian switches "this is a long-distance domestic call" and becomes redundant once you are using a country code. Including both, as +61 02, makes the call fail on most carriers. The same rule applies to mobile numbers starting with 04, which become +61 4 from abroad. The 1300 and 1800 service numbers are exceptions and have no leading 0 to drop.

What should I know about Australian DST before calling?

Daylight saving runs in Australia from early October to early April, the opposite of the Northern Hemisphere, and only some states observe it. New South Wales, Victoria, Tasmania, South Australia, and the ACT shift clocks forward one hour. Queensland, Western Australia, and the Northern Territory do not. This means Sydney and Brisbane, normally both on AEST, separate by one hour from October to April. The four-week overlap when the US has already shifted but Australia has not (and vice versa) compresses the gap to 13 to 14 hours from New York to Sydney instead of the usual 15 to 16. Always confirm in a converter before booking a call window.

What does +61 mean if it appears on my phone's caller ID?

A +61 prefix on incoming caller ID means the call originated from Australia, either dialed directly from an Australian phone or placed through a service routing through Australian infrastructure. Australia has had a high-volume scam-call problem in the past two years, and the Australian Communications and Media Authority reports that many +61 calls received in the US are spoofed by overseas scam operations to impersonate Australian callers; ACMA and US carriers have been collaborating on STIR/ SHAKEN-equivalent filtering since 2024. If you do not know an Australian, treat unexpected +61 calls with the same suspicion as any other unknown number. Legitimate calls from family or business will usually leave a voicemail.

Does +61 1300 or +61 1800 work from outside Australia?

Mostly no. Australian 1300 numbers (local-rate from inside Australia) and 1800 numbers (toll-free from inside Australia) are built on the same domestic tariff model as US 1-800 numbers and typically do not connect from foreign carriers. Some Australian banks and airlines publish a parallel direct-dial +61 number for international callers; Commonwealth Bank uses +61 2 9999 3283, ANZ uses +61 3 9683 9999, and Qantas uses +61 2 9433 2329. Always look for the "calling from outside Australia" listing on the institution's contact page rather than dialing the 1300 or 1800 number, which will either fail or bill at premium rates.
