A phone number that starts with a plus sign and the digits six, one is a number in Australia. That is the whole trick behind the Australia country code. Once you know what sits in front of the national number, everything else is just the pattern that follows: a state area code, a mobile prefix, or a toll-free string that is routed somewhere inside the country. This guide walks through all of it, from Sydney landlines to outback mobiles, with the format conventions, the quirks, and the parts that most carrier help pages leave vague.
If you are reading this on a layover in Changi or at a kitchen table in Chicago, trying to reach a cousin in Melbourne, the first thing to know is that the hard work is already done. Australia has a single country code, a tidy area code system, and well-defined mobile numbers. The second thing to know is that calling from your carrier is almost never the right way to do it anymore. More on that further down.
The short answer: +61
Australia's country code is +61, one of the codes in the ITU's list of country codes. It covers the mainland, Tasmania, and the external territories that share the national dialing plan, including Christmas Island and the Cocos (Keeling) Islands. The plus sign in front is not literally dialed. On a mobile keypad, holding the zero produces it, and the plus tells your phone to insert whichever international access prefix is appropriate for the network you are on. From a landline in the United States that would be 011, from most of Europe it would be 00, and from Japan it is 010. Modern smartphones handle all of this once you type the plus.
So the full pattern for calling Australia from abroad looks like this:
+61 + area code (without the leading 0) + local number
That one line is the rule everything else in this guide hangs off.
Dialing format, with real examples
Australian numbers follow a predictable shape. A fixed line is a two-digit area code followed by eight digits, and a mobile is a four-digit prefix followed by six digits. When you write a number domestically inside Australia, you put a zero in front of the area code or mobile prefix. That zero is called the trunk prefix, and here is the piece that trips up almost everyone calling in from overseas: drop it. The trunk zero is only for domestic dialing. The moment you prefix the number with +61, that zero disappears.
A couple of examples make this concrete. Both use number ranges the regulator sets aside for fiction and examples, so nobody real will pick up if you test them.
A Sydney office number written locally as 02 5550 1234 becomes +61 2 5550 1234 when you dial it from New York, London, or Jakarta.
A Melbourne mobile saved in a friend's contacts as 0491 570 156 becomes +61 491 570 156 from abroad.
Keep the zero and the call will not connect. You will hear a flat tone, or your carrier will complain that the number is invalid. This is the single most common failure mode when people try to call Australia for the first time, and it is worth checking twice before you blame your app or your signal.
Area codes, state by state
Australia uses four geographic area codes to cover the entire country. They map to broad regions rather than cities, so a 02 number could be anywhere from the Sydney CBD to a farmhouse near Albury on the Victorian border. If you need to know who is calling or where a number lives, think in regions. The Australian Communications and Media Authority manages the numbering plan, and the Wikipedia overview of telephone numbers in Australia has the finer-grained ranges if you are curious.
| Area code | Covers | Capital city |
|---|---|---|
| 02 | New South Wales, Australian Capital Territory | Sydney, Canberra |
| 03 | Victoria, Tasmania | Melbourne, Hobart |
| 07 | Queensland | Brisbane |
| 08 | Western Australia, South Australia, Northern Territory | Perth, Adelaide, Darwin |
When you dial any of these from outside Australia, strip the leading zero and prefix the rest with +61. A Brisbane landline that reads 07 5550 7890 at home becomes +61 7 5550 7890 on your end.
Mobile numbers all start with 04
Every Australian mobile number begins with the prefix 04 when written domestically, which becomes just 4 after +61. So a mobile is always ten digits locally, or eleven when you count the country code. Carriers in Australia all share this range, which means a 04 prefix tells you the number is a mobile but not which network it belongs to. Number portability is universal there, and a number that was once Telstra may now live on Optus or TPG Telecom (which runs Vodafone) without the owner telling anyone.
If you are calling a mobile from overseas, the format is:
+61 4XX XXX XXX
That is it. Eleven digits counting the country code, spaced however you like.
Toll-free and special numbers
Toll-free numbers in Australia use the 1800 prefix, and shared-rate business numbers use 13 or 1300. These are only reachable from inside Australia on most carriers, and some travel SIMs will refuse them even when you are on local soil. If you are abroad and need to reach a bank or an airline that only publishes a 1800 or 13 number, look for the international alternative on the company's contact page. It will usually be a plain +61 2 or +61 3 number that you can dial from anywhere.
Calling Australia from the United States, Europe, and Asia
The mechanics are the same wherever you are, but the dial-out sequence differs if your phone will not accept the plus sign (older landlines mostly).
From the United States or Canada, replace the plus with 011. The Sydney office above becomes 011 61 2 5550 1234.
From most of Europe, Africa, and large parts of Asia, replace the plus with 00. From the UK, that same number is 00 61 2 5550 1234.
From Japan the international prefix is 010, and a few other markets have their own codes, which is one more reason to let your smartphone handle it with the plus.
From a browser-based service like Phonecall, none of this matters. You enter the number in international format once, with +61 and no trunk zero, and the app handles the routing. You never think about access codes again, which is a small freedom but a real one if you call Australia regularly.
What a call to Australia actually costs
Here is where the gap between carriers and modern alternatives gets wide. International calling on a US or European mobile plan, charged out of plan or over roaming, routinely runs between one dollar and three dollars a minute to an Australian mobile. Even some providers that advertise international add-ons charge thirty to fifty cents a minute to Australia on top of the subscription.
Phonecall charges $0.15 per minute to Australian mobiles and $0.05 per minute to landlines, billed per second rather than rounded up to the nearest minute. Both are listed on the rates page. There are no connection fees, no monthly commitment, and no bundle you have to activate. New accounts get 30 seconds of free call time on signup so you can hear the quality for yourself before you add credit. Across 218 countries, the pricing stays per-minute and transparent in the same way, which matters if your contacts are scattered.

The savings math is simple. A fifteen-minute call to a mobile in Perth over a US carrier's international rate can easily cost twenty dollars. The same call through Phonecall is $2.25, and if the person you are calling has a landline, it drops to $0.75. Multiply that by a weekly check-in with a family member and the difference adds up inside a month.
When your call will not connect
Troubleshooting international calls to Australia is almost always one of five issues, in rough order of frequency.
The leading zero problem. You left the trunk zero in after +61. Drop it. The number after +61 should be nine digits, whether it is a mobile or a landline.
Wrong country code. If you accidentally dialed +64 you reached New Zealand, which is a surprisingly common slip because the two codes look alike. +61 is Australia, +64 is New Zealand.
The number is 1800, 13, or 1300. These shared-rate and toll-free numbers do not accept international calls. Find a geographic +61 2 or +61 3 alternative.
Blocked by your carrier. Some mobile plans in the US block all outgoing international calls by default as an anti-fraud measure. You usually need to enable international calling in your account settings or by calling customer support. A browser-based calling app sidesteps this entirely because the call originates from the internet, not your carrier.
Time zone issue, not a connection issue. The call connects, but no one picks up because it is three in the morning in Melbourne. See the next section.
Time zones, and the daylight saving maze
Australia spans three primary time zones, one of them on a half-hour offset that trips up calendars worldwide.
Australian Eastern Standard Time, AEST (UTC+10), covers New South Wales, Victoria, Tasmania, the Australian Capital Territory, and Queensland.
Australian Central Standard Time, ACST (UTC+9:30), covers South Australia and the Northern Territory. Yes, half an hour. Yes, really.
Australian Western Standard Time, AWST (UTC+8), covers Western Australia.
Daylight saving in Australia is where things get interesting. New South Wales, Victoria, Tasmania, South Australia, and the ACT observe daylight saving from the first Sunday in October to the first Sunday in April, pushing their clocks forward by one hour. Queensland, Western Australia, and the Northern Territory do not observe daylight saving, which means that for roughly half the year, Brisbane is on the same clock as Sydney, and for the other half, Brisbane is an hour behind. Adelaide stays half an hour behind Sydney all year because both switch together, while Darwin goes from half an hour behind Sydney in winter to an hour and a half behind in summer.
For a US-based caller, the rough rule is that Sydney is fourteen to sixteen hours ahead of New York, depending on which end has daylight saving active. A sensible calling window is early evening in New York, which lands in the Sydney morning the following day, or mid-afternoon Pacific time, which also lands in the Sydney morning. The afternoon in Sydney is the small hours in London, while the Sydney evening lines up with a reasonable morning in Western Europe.
Emergency numbers in Australia
If you are calling Australia on behalf of someone in trouble, or if you are traveling in Australia and need help, the numbers to know are these.
000 (Triple Zero) is the primary emergency number across the entire country for police, fire, and ambulance. It works from any landline, mobile, or payphone, including a locked mobile. Dispatchers will ask which service you need.
112 is the international mobile emergency number and reaches the same operators as 000 when dialed from a mobile. Despite rumors, 112 is not a hidden signal booster or secret override. It is simply a parallel emergency number.
106 is the text-based emergency number for people with hearing or speech impairments, operated through a TTY.
These numbers are for Australian emergencies and are only reachable from inside Australia. If you are abroad and need to raise an alarm about someone in Australia, call the embassy or consulate of your country or reach a family member in Australia directly.
Travelers calling home, migrants calling home, and everyone in between
The three groups who make international calls to and from Australia most often are not the same group. A migrant in Sydney calling family in Manila or Mumbai or Shanghai has very different needs from a Melburnian backpacker in Lisbon calling home, which is different again from a Chicago grandparent calling a daughter in Brisbane. What they share is that none of them should be using carrier roaming or international add-ons by default. The pricing has moved on.
For the migrant case, a browser-based calling app on a laptop or a phone, calling out over WiFi or home broadband, routes the call through the internet to the destination carrier for a flat per-minute rate. The same account that calls Australia can also call the Philippines, India, or Indonesia at the rates published for each, without juggling different providers.
For the traveler case, the same app running on a phone over hotel WiFi or an eSIM data plan avoids the roaming trap entirely. You pay for data (often free) and the per-minute call rate, and nothing else. If you are traveling onward from Australia to New Zealand or back home to the United Kingdom or the United States, the same account carries over. The official tourism site, Australia.com, is the place to plan the rest of the trip.
For the inbound-caller case, the person in Chicago or Berlin ringing a loved one in Australia, the app runs in a browser tab. No download, no SIM change, no new number to memorize. You enter +61 followed by the nine digits that remain once the leading zero is gone, and the call connects over the internet.
Dialing the specific places
If you want to know the local area code for a specific capital, here is the quick reference. All of these drop the leading zero when prefixed with +61.
Sydney, New South Wales: 02, so +61 2.
Melbourne, Victoria: 03, so +61 3.
Brisbane, Queensland: 07, so +61 7.
Perth, Western Australia: 08, so +61 8.
Adelaide, South Australia: 08, so +61 8.
Canberra, Australian Capital Territory: 02, so +61 2 (ACT shares the New South Wales area code).
Hobart, Tasmania: 03, so +61 3 (Tasmania shares the Victoria area code).
Darwin, Northern Territory: 08, so +61 8.
Note that an area code only tells you the region, not the city. A +61 8 number could belong to someone in central Perth, suburban Adelaide, or a cattle station in the Northern Territory.
Making the call
Pick up any phone, type the plus, then 61, then the area code without the leading zero, then the local number. If you want it cheaper and clearer than a carrier roaming call, open the Phonecall dialer in a browser, sign in, and dial. You get the first 30 seconds free to test the line, then $0.15 per minute to an Australian mobile or $0.05 to a landline from that point on, with the same transparent per-second billing applied to 218 countries if your contacts are scattered beyond Australian borders.
The country code is just +61. What you do with it is up to you.
