This guide walks you through everything you need to know to call Australia from the US — from the correct dialing format and country codes to the most affordable call methods.
Understanding the basics of calling Australia from the US
When calling Australia from the United States, the key to a successful connection is getting the dialing sequence right. Every international call follows a specific order — starting with the US exit code, followed by Australia’s country code, the local area code, and finally, the phone number. Missing or misplacing a single digit can cause your call to fail or route incorrectly.
Landlines vs. mobiles:
- Landlines: Typically start with a 0 when dialed within Australia (e.g., 02 for Sydney). When calling internationally, drop the leading zero.
- Mobile numbers: Start with 04 domestically, but when dialing from abroad, you’ll use 011 61 4, followed by the remaining digits.
For example, a mobile number written as 0412 345 678 in Australia becomes 011 61 412 345 678 when calling from the US.
Step-by-Step Guide to Dialing Australia from the US
Dialing Australia from the United States follows a simple pattern once you know the correct sequence. Follow these four steps to make sure your call goes through smoothly so you can catch up, collaborate, or check in without interruption.
Step 1 – dial the US exit code
Every international call made from the United States begins with the exit code 011. This code tells your phone carrier that you’re calling outside the country.
Tip: On most mobile devices, you can replace “011” with a plus sign (+) by holding down the 0 key. For example: +61 [area code] [local number].
Step 2 – enter Australia’s country code
Next, dial 61, which connects your call to Australia’s national telephone network.
At this point, your number will look like:
011 61 or +61, depending on the device you’re using.
Step 3 – add the Australian area code
After the country code, include the one-digit area code for the region or city you’re calling. Just remember to drop the leading zero used in local Australian numbers.
Common Australian area codes:
| City / region | Local code | Dial from the US as… |
| Sydney | 02 | 2 |
| Melbourne | 03 | 3 |
| Brisbane | 07 | 7 |
| Perth | 08 | 8 |
| Adelaide | 08 | 8 |
For example, to call a Sydney number listed as 02 9876 5432, dial 011 61 2 9876 5432.
Step 4 – dial the local phone number
Finally, enter the subscriber’s local number.
- Landlines in Australia are typically 8 digits long.
- Mobile numbers begin with 04 domestically but are dialed as +61 4 internationally.
Examples:
- To call an Adelaide landline: 011 61 8 8234 5678
- To call an Australian mobile: 011 61 412 345 678
Recommended call methods for contacting Australia
There are several ways to call Australia from the United States, each offering different benefits in terms of cost, convenience, and quality. The right method depends on how often you make international calls and the technology you use.
Use VoIP for cost-effective and reliable calls
The most affordable and efficient way to call Australia is through VoIP (Voice over Internet Protocol). VoIP routes your call over the internet instead of traditional telephone lines, giving you crystal-clear audio, lower rates, and global flexibility.
With Voiso, you can make calls from any device — computer, tablet, or smartphone — without needing a separate phone plan or special equipment.
Benefits of using Voiso include:
- Consistent, high-quality calls, even across long distances.
- Lower costs compared to traditional carriers.
- Flexible device options, allowing you to call from anywhere with an internet connection.
- Transparent billing and analytics for cost control and visibility.
Whether you’re calling for business or personal reasons, Voiso ensures every connection is smooth, professional, and cost-effective.
Mobile or landline carrier international calling
You can also make international calls to Australia using your existing mobile or landline carrier. Most US providers — including AT&T, Verizon, and T-Mobile — offer international calling features or add-on plans that include Australia.
Pros:
- Simple setup using your current number.
- Reliable connection through your existing network.
Cons:
- Higher per-minute rates than VoIP.
- Costs can vary depending on time of day and carrier.
- Limited features for business use.
For frequent calls or long conversations, this option can become expensive compared to a VoIP solution like Voiso.
International calling cards
Another alternative is to use a prepaid international calling card, which lets you pay upfront for a set number of minutes to call Australia. These cards can be purchased online or at retail stores.
While calling cards may seem convenient, many include hidden connection fees, minute rounding, or expiration dates, making them less cost-effective in the long run.
Tip: If you make regular calls to Australia, a VoIP platform like Voiso is a more transparent choice, offering reliable connectivity without the extra costs or fine print.
Tips for making successful international calls to Australia
Once you’ve mastered the dialing format, a few simple habits can make every international call clearer, smoother, and more cost-effective. Follow these tips to ensure you stay connected — no matter which side of the Pacific you’re on.
1. Save contacts in the correct international format
Always store Australian numbers in full international format to avoid connection issues. Use +61, followed by the area or mobile code (without the leading zero) and the local number.
For instance, a Sydney number written as 02 9876 5432 should be saved as +61 2 9876 5432.
This makes it easier to call or message contacts through apps or VoIP platforms when traveling or switching devices.
2. Test your connection before important calls
If you’re using a VoIP service, test your internet connection and audio setup before major business or client calls.
- Check Wi-Fi strength or switch to a wired connection for better stability.
- Close unnecessary apps to free up bandwidth.
- Use a headset or dedicated microphone for clearer sound.
3. Be mindful of time zones and availability
Australia is often a full day ahead of the United States, so plan accordingly. For most regions, morning hours in the US line up with late evening hours in Australia.
If it’s a business call, aim for Australia’s working hours (9 AM–5 PM local time) to ensure your contact is available.
4. Avoid peak calling hours to save money
If you’re using a traditional carrier, international rates often spike during peak periods — evenings and weekends, in particular. VoIP calls through Voiso avoid these fluctuations entirely, giving you consistent pricing and stable call quality no matter when you connect.
5. Keep backup options handy
Even with the best planning, network or connectivity issues can happen. Save a secondary contact method — like email or messaging apps — so you can easily follow up if a call drops or doesn’t connect.
