How to call Australia from the UK: dialing in 2026

The dial string is +61 followed by the Australian national number with the leading 0 dropped. Australian toll-free and local-rate prefixes (1800, 13, 1300) are domestic only and will not connect from the UK. Most of Australia sits 9-11 hours ahead of UK time, so the useful overlap for office calls is a UK morning window.

The dial string

To call Australia from the UK:

• ›+61 {area code or mobile} {number}, or
• ›00 61 {area code or mobile} {number} from a UK landline.

Drop the leading 0. A Sydney landline printed as 02 9374 4000 becomes +61 2 9374 4000. An Australian mobile printed as 0412 345 678 becomes +61 412 345 678.

Mobile vs landline

Australian mobiles start with 04 domestically; after dropping the 0, dial +61 4xx xxx xxx. Landline area codes are single-digit after the trunk 0: Sydney/NSW 2, Melbourne/VIC 3, Brisbane/QLD 7, Adelaide/SA 8, Perth/WA 8 (with distinct subscriber ranges), Canberra 2.

Australia does not bill the receiver for ordinary incoming international calls.

What it costs

Four realistic routes for a UK→Australia call in 2026:

• ›UK mobile international add-on. Australia sits outside EE/Vodafone/O2 Europe-inclusive bundles. Without an International Pass, pay-as-you-go to Australian mobiles is commonly £1.00, £1.80/min on major UK networks (confirm on the carrier price guide).
• ›Pre-paid international calling card. Low headline landline rates; connection fees hurt short calls to ATO or bank IVRs.
• ›VoIP app-to-phone. Teams Phone and Viber Out terminate to Australian mobiles at low-to-mid US-cent equivalent rates.
• ›Browser-to-phone via WorldDial. From $0.11/min to Australian mobiles and $0.04/min to landlines on the public rates table, see call Australia.

For regular UK→Australia traffic, an International Pass can win on short calls; for long holds, per-minute browser/VoIP routes beat raw pay-as-you-go.

Toll-free numbers from this corridor

Australian 1800 (toll-free) and 13/1300 (local-rate) numbers do not work from the UK. Institutions publish a paid +61 geographic or mobile contact alongside those domestic lines, dial that. UK foreign-travel advice for Australia is at gov.uk.

Best calling windows

Australian Eastern Standard Time is UTC+10 (AEDT UTC+11 in summer). The UK is UTC+0 / UTC+1. Sydney/Melbourne run about 9-11 hours ahead of the UK.

Best overlap for a human on an Australian helpline: 08:00-11:00 UK time, which maps to late afternoon/early evening in Sydney (19:00-21:00 AEST in UK winter, shifting with DST). That window still catches many bank and government lines before they close for the Australian evening.

Western Australia (Perth, UTC+8) is two hours behind the east, a UK 08:00 start is mid-afternoon Perth time and often quieter than Sydney’s end-of-day rush.

Avoid calling Australian government lines on Australian public holidays and during the mid-afternoon east-coast peak when local callers flood queues.

Pitfalls specific to this corridor

• ›State time zones. Booking a “9 AM Australia” callback without naming the state misses by up to three hours (Queensland has no DST; Western Australia sits behind the east coast). Write the state abbreviation next to every appointment time.
• ›13 numbers look short and fail internationally. Always convert to the full +61 published alternative before leaving the contact page.
• ›DTMF on ATO and bank IVRs. Long menus; test tones before settling into a hold. If the menu ignores keypresses, switch route immediately rather than waiting on hold music with a broken DTMF path.
• ›Number portability across Telstra, Optus, and Vodafone AU. CLI may not match the brand the callee expects; the call still completes.
• ›Australian public holidays vs UK ones. Australia Day, ANZAC Day, and state-specific holidays close contact centres while the UK is open. Check the destination state’s holiday calendar before an early UK-morning attempt.

Quick checklist

• ›Dial +61 with the leading 0 dropped.
• ›Replace 1800/13/1300 with a paid +61 line.
• ›Prefer 08:00-11:00 UK time for east-coast offices.
• ›Confirm which Australian state/time zone the office uses.
• ›Use a per-minute route unless a UK International Pass already covers Australia cheaply.
