Call Australia from United Kingdom

When calling internationally, it's important to consider time zone differences to ensure you're calling at a convenient time.

When calling the United Kingdom, which operates on GMT (UTC+0) in winter and BST (UTC+1) in summer, aim for late morning to early afternoon your time if you're calling from the Americas, or early evening if calling from Asia to catch UK business hours (9 AM-5 PM). Remember that the UK switches to Daylight Saving Time on different dates than many countries, typically the last Sunday in March and October, so verify the current time difference before important calls. When calling Australia, keep in mind the country spans three main time zones: AEST/AEDT (UTC+10/+11), ACST/ACDT (UTC+9.5/+10.5), and AWST (UTC+8), with most major cities in the eastern zone. For the best results, call during Australian business hours (9 AM-5 PM local time) and remember that Australia observes daylight saving time from October to April in most states, which can shift the time difference by an additional hour.
