Millions of Australians to get an extra hour of sleep tonight as daylight savings winds up across four states

Australians across four states will get an extra hour of sleep on Sunday morning thanks to the end of daylight savings.

Clocks will revert to Australian eastern standard time at 3am on Sunday, which means the time will jump back to 2am for people living in NSW, Victoria, the Australian Capital Territory, Tasmania, and South Australia.

This means all of Australia's eastern states will reunite with Queensland and run on the same time zone, with the sunshine state opting out of daylight savings.

South Australian and Northern Territory residents will also both run on Central Standard Time.

Residents in Queensland and Western Australia will not need to wind their clocks back as these states do not observe daylight savings.

Australians will find it a little more straightforward without daylight savings, as the nation drops two of the five separate time zones that were in place during summer.

The Northern Territory, South Australia, and the outback NSW town of Broken Hill will all be half an hour behind on Australian Central Standard Time (ACST).

Western Australia will be a full two hours behind the AEST states and territories on Australian Western Standard Time (AWST).

Daylight savings is set to return at 2am on October 6, when Australians in most parts of the East Coast will turn their clocks back one hour for an extra 60 minutes of sunlight in the evenings.
