over 74,000 respondents participating, 64 percent of whom voted in favour of a trial and 63% were in favour of holding a referendum. The decision announced by the Premier on 7 June 2010 was that her Government would not support the Bill, because regional Queenslanders were overwhelmingly opposed to daylight saving. The Bill was defeated in Queensland Parliament on 15 June 2011. Western Australia Western Australia also had a particularly involved debate over daylight-saving time, with the issue being put to a referendum four times, 1975, 1984, 1992 and 2009. All were defeated. Voters returned a "no" vote of 54.57% in 2009, the highest in all four referendums. Each referendum followed a trial period during which the state observed daylight saving time. The first three followed a one-year trial, while the 2006 Western Australian Daylight Saving Bill (No. 2) 2006 instituted a daylight-saving trial that began on 3 December 2006 and lasted for three years. The referendum was defeated in 2009. Special events In 2000, all eastern jurisdictions that normally observe daylight-saving time – New South Wales, Victoria, the Australian Capital Territory and Tasmania – started daylight-saving time early, due to the 2000 Summer Olympics in Sydney. These jurisdictions changed on 27 August 2000. South Australia did not change until the regular time, which that year was on 29 October. In 2006, all states that followed daylight-saving time (the above listed states plus South Australia) delayed the return to their respective Standard Times by a week, due to the 2006 Commonwealth Games in Melbourne. Daylight-saving time ended on 2 April 2006. History Daylight saving was first used in Australia during World War I, and was applied in all states. It was used again during the Second World War. A drought in Tasmania in 1967 led to the reintroduction of daylight saving in that state during the summer, and this was repeated every summer since then. In 1971, New South Wales, Victoria, Queensland, South Australia, and the Australian Capital Territory followed Tasmania by observing daylight saving. Western Australia and the Northern Territory did not. Queensland abandoned daylight saving time in 1972. Originally Tasmania alone commenced daylight saving on the first Sunday in October, while the other states began on the last Sunday in October and finished on the last Sunday in March, until 2008. From 2008/09 daylight saving has been extended another four weeks in NSW, Victoria, SA and the ACT,
