Daylight Saving Time History in Australia

- Australia has observed DST for 64 years between 1916 and 2025 (DST in at least one location).
- Previous time with no Daylight Saving Time was 1966.
- See Worldwide DST Statistics
On October 2, 1916, during World War I, Tasmania became the 1st state in Australia to use DST. The measure was applied in all Australian states and territories in 1917. It was removed in the whole country in 1918. Seasonal change was reintroduced during World War II, when it was used from 1942 to 1944.
After the end of the war, DST was not observed in any Australian state or territory until October 1, 1967, when Tasmania reintroduced it during a drought. The state has continued changing its clocks ever since.
In 1971, the Australian Capital Territory, New South Wales, South Australia, Victoria, and Queensland followed Tasmania.
Queensland abandoned DST already in 1972 and, with the exception of a trial from 1989 to 1992, it has not been in use. Western Australia conducted a DST trial from 2006 to 2009, but it was abandoned for its unpopularity. The Northern Territory has not used DST since 1944.
