Australian Daylight Saving Begins

On the first Sunday of October, clocks go forward one hour at 2:00am local time across New South Wales, Victoria, South Australia, Tasmania and the ACT. Sydney and Melbourne move from UTC+10 to UTC+11, and Adelaide from UTC+9:30 to UTC+10:30. Queensland, the Northern Territory and Western Australia do not observe daylight saving at all, so from this date Australia runs on five distinct offsets simultaneously, one of the most fragmented timezone pictures anywhere in the world. For anyone scheduling from the UK, the gap to Sydney widens to ten hours, then to eleven once British Summer Time ends later in the month.
