Australian Time Zones and Daylight Saving Dates

The size of Australia means that we have three times zones. That is complicated by some states using daylight saving while others don't.

Australian Time Zones – all states of Australia

Eastern states – Queensland, New South Wales and the Australian Capital Territory, Victoria and Tasmania – are on Australian Eastern Standard Time (AEST) which is UTC/GMT plus 10 hours.

South Australia and the Northern Territory are on Australian Central Standard Time (ACST) which is UTC/GMT plus 9.5 hours.

Western Australia is on Australian Western Standard Time (AWST) which is GMT plus 8 hours.

Australian Daylight Saving (summer time) Dates

New South Wales (including the ACT), Victoria, South Australia and Tasmania move their clocks forward one hour on the first Sunday in October and back one hour on the first Sunday in April.

Western Australia had a three year daylight saving trial from 2006 to 2009. They voted against daylight saving in 2009 and now maintain Western Standard Time all year round.

Queensland maintains Eastern Standard Time all year round. This causes much debate every year in the south-eastern corner of the state, and particularly on the Gold Coast which straddles the border.

The Northern Territory, also in the tropics, do not change their clocks.

What to do to changeover:

The night before the start of daylight savings time, set your clocks forward one hour.

The night before the end of daylight savings time, set your clocks back one hour
