UTC- Coordinated Universal Time
Some Australian states and territories use daylight savings time from the first Sunday in October to the first Sunday in April. However, this is not the case in all Australian states. The states that adopt the time difference (moving the watch hand one hour ahead) are New South Wales, Victoria, South Australia, Tasmania and the ACT.
In Queensland, Western Australia and the Northern Territory the time of day always stays the same.
Therefore, during the Australian summer, a puzzling situation is created: Sydney is an hour ahead of Brisbane, even though Brisbane is geographically further east! With summer time also coming into force in Europe, this helps to influence the time zone between our home countries and Australia
