The state of Western Australia is planning to adopt daylight saving time on a trial basis till 31 March 2009. This has not yet been passed by parliament but is supported by both major parties.

The initial period is 2am 1 December 2006 to 2am 25 March 2007.

Subsequent periods are 2am on last Sunday in October till 2am on last Sunday in March.

The Daylight Saving Bill 2006 can be found on http://www.parliament.wa.gov.au/ . Unfortunately there is no fixed address.
