The clocks in these regions are turned backward by one hour at 3 am on the first Sunday of April and forward by one hour at 2 am on the first Sunday of October. The states of Queensland, Western Australia, and the Northern Territory do not observe DST. Lord Howe Island, located northeast of Sydney, follows DST but only sets the clocks forward by 30 minutes.

What You'll Learn

Daylight Saving Time (DST) ends on the first Sunday of April
The Australian states that observe DST are New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory. Queensland, Western Australia, the Northern Territory, and other external territories do not observe DST.
The impact of DST on sleep health is a topic of interest for many Australians. Some sources suggest that the change can be particularly disruptive when the clocks go forward in October, as people may lose an hour of sleep if they are not prepared. However, when DST ends in April, people can benefit from an extra hour of sleep as the days get cooler.
The history of DST in Australia dates back to World War I, when it was first applied in all states. It was used again during World War II and then reintroduced in Tasmania in 1967 due to a drought. In 1971, several other states adopted DST, but it has since been abandoned in some places, such as Queensland and Western Australia, due to unpopularity or public debate.
Lord Howe Island, located off the coast of Australia, observes DST, but the clocks only move forward by 30 minutes.

Clocks go back one hour at 3 am local daylight time
In Australia, Daylight Saving Time (DST) ends on the first Sunday of April and resumes on the first Sunday of October. DST ends at 3 am local daylight time, when clocks are turned back by one hour to 2 am local standard time. This means that sunrise and sunset occur one hour earlier than the previous day, resulting in more morning light and less light in the evening. DST in Australia is observed in the Australian Capital Territory, New South Wales, Norfolk Island, South Australia, Jervis Bay Territory, Tasmania, and Victoria.
Queensland, Western Australia, the Northern Territory, and other external territories do not observe DST. The decision to use DST is made by each state or territory, and historically, the implementation of DST has varied across different regions.
The transition to and from DST can impact sleep schedules, with some individuals finding it challenging to adapt to the time change. However, the benefit of ending DST is that it allows for an easier shift to an earlier sleep schedule, which may be advantageous for those who prefer sleeping earlier but struggle to make the adjustment.
It is important to note that not all devices will automatically adjust to the time change. While smartphones and laptops typically update the time, analogue clocks, watches, ovens, and microwaves often require manual adjustment.

Sunrise and sunset are one hour earlier
In 2025, the clocks in Australia will change on Sunday, April 6, and Sunday, October 5. On April 6, at 3 am local daylight time, clocks will be turned back an hour to 2 am local standard time. This change will result in sunrise and sunset occurring approximately one hour earlier than the previous day. This phenomenon is often referred to as "Fall Back" or "Winter Time."
The impact of this clock change is that there will be more daylight in the mornings and less daylight in the evenings. This can be advantageous for those who prefer early morning strolls or desire an extra hour of sleep during the darker mornings. However, it also means that the evenings will become darker earlier, which may impact evening activities or commuting.
The transition back to local daylight time will occur on October 5, at 2 am local standard time. The clocks will be turned forward by one hour to 3 am local daylight time. Consequently, sunrise and sunset will occur about one hour later than the previous day, resulting in more evening daylight and less morning daylight. This change is often called "Spring Forward," "Summer Time," or "Daylight Savings Time."
It's important to note that not all states in Australia observe Daylight Saving Time (DST). Queensland, Western Australia, the Northern Territory, and some external territories do not adjust their clocks for DST. Additionally, Lord Howe Island, located off the coast of New South Wales, only adjusts its clocks forward by 30 minutes for DST instead of the typical one-hour change. These exceptions create variations in sunrise and sunset times across the country.

DST returns on the first Sunday of October
In Australia, Daylight Saving Time (DST) returns on the first Sunday of October. Not all parts of Australia use DST, and some states do not observe it at all. Queensland, Western Australia, the Northern Territory, and Australia's external territories do not change their clocks for DST.
In 2025, DST will return on Sunday, October 5, at 2:00 a.m., when clocks will be turned forward by one hour to 3:00 a.m. local daylight time. This change will bring longer evenings with more light and less light in the mornings. This is also known as "Spring Forward" or "Summer Time."
The Australian Capital Territory, New South Wales, Victoria, South Australia, and Tasmania observe DST. Lord Howe Island, located northeast of Sydney, also observes DST, but clocks only move forward by 30 minutes, from UTC+10:30 to UTC+11.
DST was first introduced in Australia during World War I, and it was applied in all states. Tasmania was the first state to adopt DST in 1916, and the rest of the country followed in 1917. DST was removed in 1918 but was reintroduced during World War II from 1942 to 1944. After the war, DST was not observed until Tasmania brought it back during a drought in 1967.
The impact of DST on sleep health is a topic of interest. While some people may struggle with the transition, research suggests that sleep naturally adapts over time, and small adjustments in the days leading up to the change can help.

Lord Howe Island, located about 600 kilometres northeast of Sydney, observes DST but only moves its clocks forward by 30 minutes.
The history of DST in Australia dates back to 1916 during World War I, when it was first observed. Tasmania was the first state to adopt DST in 1916, and by 1917, it was applied in all Australian states and territories. However, in 1918, DST was removed from the entire country. DST was reintroduced during World War II from 1942 to 1944. After the war, DST was not observed in any Australian state or territory until 1967, when Tasmania brought it back during a drought.
The impact of DST on sleep health has been a topic of discussion, with some research suggesting that sleep naturally adapts over time to DST transitions. However, individuals who struggle with these transitions can benefit from making small adjustments in the days leading up to the change.
