Making an international call requires the correct dialing format so the phone network can connect your call to the right country. When placing a call from the United States to Australia, you need to use the proper exit code, the Australian country code, and the destination phone number.
This guide explains how to call Australia from US, including the correct dialing structure, how Australian numbers are formatted, and common mistakes to avoid when calling internationally.
1. Calling Australia from the US: What You Need to Know First
International calls follow a different dialing process compared with domestic calls. Before learning how to call Australia from US, it helps to understand the key details that allow your phone network to route the call correctly between countries.
First, international calls from the United States require an international access code. This code tells the phone network that the call is leaving the country and must be routed through international telephone systems.
Second, you must dial the country code for Australia, which directs the call to the Australian national phone network. After the country code, the call continues to the correct area code or mobile number within Australia.
Many people also ask, “Do I need to dial 011 to call Australia?”. In most cases the answer is yes. The number 011 is the standard international exit code used when dialing from the United States. This code must be entered before the Australian country code so the call can connect properly.
Having the correct dialing information ready including the exit code, country code, and phone number makes it much easier to place a successful international call.

2. The Correct Dialing Format for Calling Australia
Understanding the dialing structure is an important part of learning how to call Australia from US. International calls follow a specific order of numbers that guide the call through the global telephone network.
Some people also want to know how much does it cost to call Australia. The cost depends on the phone carrier and the type of service plan being used. Some providers charge international per minute rates while others include international calling features within certain plans.
US International Exit Code
The international exit code for the United States is 011. This number must be dialed first whenever you place a call from the US to another country.
Dialing 011 tells the phone network that your call is international rather than a domestic call within the United States.
Australia Country Code
The country code for Australia is 61. After dialing the US exit code, you enter 61 to route the call to Australia.
The full dialing structure usually follows this format: 011 + 61 + area code (without the leading 0) + local phone number
Using the correct dialing sequence helps ensure the call connects successfully when calling Australia from the United States.

3. How Australian Phone Numbers Are Structured
Understanding how phone numbers are organized in Australia helps avoid dialing mistakes when learning how to call Australia from US. Australian numbers follow a structured format that includes an area code or mobile prefix followed by the local subscriber number.
When dialing internationally, the structure of the number remains mostly the same except for one important change. The leading zero used in domestic Australian numbers is removed when dialing from another country. This step allows the international phone network to route the call correctly through the Australian system.
Many people also ask, “Can I call Australia for free from a mobile?“. The answer depends on the mobile carrier and the type of phone plan you use. Some providers charge international per minute rates, while others include international calling options in certain service plans. Having a plan that supports international calling can make it easier and more affordable to contact numbers in Australia.
Landline Area Codes in Australia
Australian landline numbers include an area code that identifies the region. These area codes normally start with a zero when dialed inside Australia.
Some common Australian landline area codes include:
- 02 for New South Wales and the Australian Capital Territory
- 03 for Victoria and Tasmania
- 07 for Queensland
- 08 for Western Australia, South Australia, and the Northern Territory
When dialing from the United States, the leading zero is removed. For example, a number written locally as 02 1234 5678 would be dialed internationally as: 011 61 2 1234 5678
Removing the zero is a key step when placing international calls to Australian landlines.
Australian Mobile Number Format
Mobile numbers in Australia follow a slightly different structure from landlines. Australian mobile numbers typically start with 04 when dialed domestically.
For example: 0412 345 678
When calling from the United States, the leading zero is removed and the number becomes: 011 61 412 345 678
This format allows the call to be routed correctly to Australian mobile networks.
4. Common Problems When Calling Australia Internationally
Even when you know the dialing format, small mistakes can prevent the call from connecting. Understanding these common errors can help ensure success when learning how to call Australia from US.
Keeping the Leading Zero
One of the most frequent mistakes is keeping the leading zero in Australian numbers. Domestic numbers in Australia usually begin with a zero, but this zero must be removed when dialing internationally.
For example, with domestic format: 04 1234 5678
Correct international format: 011 61 412 345 678
If the zero is not removed, the call may fail to connect.
Using the Wrong Dialing Prefix
Another common issue is dialing the wrong international prefix. Different countries use different exit codes. Some regions use 00, but calls from the United States must begin with 011.
If the incorrect prefix is used, the international call may not go through.
Dialing the Wrong Country Code
The country code is what directs the call to the correct national network. Australia uses the country code 61.
Dialing the wrong country code can send the call to a completely different country or prevent the call from connecting at all. Checking the correct country code before dialing helps avoid this problem.
5. Make International Calls to Australia Without High Calling Costs
International calling rates can vary widely depending on the mobile carrier. For many users, calling overseas regularly can lead to high charges if international calls are billed per minute. Choosing a phone service that includes international calling options can help reduce these costs when learning how to call Australia from US.
