How to Call Australia from the US?
If you are planning to call Australia from the US, you need to use the correct Australian phone number format when dialing. Here’s a step-by-step procedure to call an Australian landline or mobile number from the US:
Calling Australian Landlines
To call Australian landline from the US, you need to know the location of the recipient you are planning to call or the area code of their city.

Let’s look at the complete procedure for dialing an Australian landline number:
Step 1: Dial the US Exit Code (+ or 011)
The 011 code, known as the US exit code, is required when dialing from a landline to inform the carrier that the call is international and must be routed outside the country.
Step 2: Enter Australia’s country Code (61)
To call Australia, you must dial the country code 61. After the US exit code (or the plus symbol), the full international number should begin with either +61 or 01161 to ensure your call reaches the correct country.
Step 3: Add the Area Code (Without the Leading 0)
Australian landline numbers use local Australia area codes, similar to those in the US. However, since Australia has only four two-digit area codes and you omit the leading zero when dialing internationally, you only need to remember one significant digit for the area code.
Here are the main Australian area codes:
- Sydney (NSW) – 02
- Melbourne (VLC) – 03
- Brisbane (QLD) – 07
- Perth (WA) – 08
Step 4: Dial the 8-Digit Local Landline Number
After the area code, enter the remaining 8-digit landline number.
An example of calling someone in Melbourne, from the US, looks like 011 61 3 1234 5678.
Calling Australian Mobile Numbers
Calling an Australian mobile number from the US is similar to calling landline numbers, except you have to replace the area codes with the mobile phone codes, which is 4.

Here’s a simple process for calling an Australian mobile phone:
Step 1: Dial the US Exit Code (+ or 011 )
Start by dialing the US exit code 011, or use the plus symbol (+) if you are on a smartphone or mobile device.
Step 2: Enter Australia’s Country Code (61)
Enter 61, the country code for Australia, to ensure your call is routed correctly.
Step 3: Add the Mobile Prefix (4) – Remove the Leading Zero
When calling an Australian mobile phone, the standard landline city code is replaced by the digit 4. This is because all Australian mobile numbers use the 04 mobile prefix, but the leading zero is always omitted when dialing international calls from the US.
Step 4: Dial the Local Mobile Number
Complete the dialing process by entering the rest of the recipient’s local phone number.
Following the USA exit code/plus sign (+011), the country code (61), and the mobile code (4), finally the phone number is dialed, completing the full sequence for an eight-digit number like 1234-5678 as 011 61 4 1234 5678.
| Type | Local Format | U.S. Dialing Format |
| Landline | (03) XXXX XXXX | 011 61 3 XXXX XXXX |
| Mobile | (04) XXXX XXXX | 011 61 4 XXXX XXXX |

When is the best time to Call Australia from the US?
Working with Australian clients requires careful consideration of the significant time difference, which can be nearly half a day. While using a map or Google is the easiest way to check the time, calculating it requires knowing two key facts:
- Australian Daylight Saving Time (DST): This runs from October to April, so the US is typically on Standard Time when much of Australia is on Daylight Time (and vice versa).
- Uneven DST Observation: Only certain Australian regions (ACT, NSW, SA, Tasmania, Victoria, and Norfolk Island) observe DST.
Based on these two facts, there are three standard time zones based on Australia’s mainland territories and states:
| Time Zone | States/Territories Covered | Eastern Daylight Time (EDT) | Eastern Standard Time (EST) | Pacific Daylight Time (PDT) | Pacific Standard Time (PST) |
| AEST (Australian Eastern Standard Time) | New South Wales (except Broken Hill), Queensland, Tasmania, Victoria, Australian Capital Territory | 14 hours | 15 hours | 17 hours | 18 hours |
| ACST (Australian Central Standard Time) | South Australia, Northern Territory, Broken Hill (NSW) | 13.5 hours | 14.5 hours | 16.5 hours | 17.5 hours |
| AWST (Australian Western Standard Time) | Western Australia | 12 hours | 13 hours | 15 hours | 16 hours |
