In a country with multiple time zones and different Daylight Saving Time rules for each state, the easiest way to check current time and time differences (GMT offsets) is by city.
There are three standard time zones in Australia:
Summer Time (Daylight Saving Time) is currently in use in New South Wales, the Australian Capital Territory, Victoria, South Australia and Tasmania from the first Sunday in October through to the first Sunday in April.
Northern Territory, Queensland and Western Australia do NOT use DST.
Australia is divided into six states: New South Wales, Victoria, Queensland, South Australia, Western Australia and Tasmania and 2 territories, the Australian Capital Territory and the Northern Territory.
