Australian time zones

Time zones in Australia can be a bit confusing, especially when only certain states across the continent observe Daylight Savings Time (late October to late March), marking the official beginning of summer. This means that Australia's times zones follow state borders both vertically and horizontally. Greenwich Mean Time (GMT) is not affected by Daylight Savings Time (DST), providing a standard to calculate differences in time zones. In the table below, the rows on the left represent where you are. The columns across the top represent where you wish to know the time. To calculate the time in a different zone, simply add or subtract the difference in hours between the two places. For example, if it is noon in GMT, then it is 10pm in Victoria. Remember that the date is affected in some cases---Australia is ahead of the Western Hemisphere, so Monday evening in New York is Tuesday morning in Sydney. All regions that observe DST have an asterisk. Therefore, during DST, if you start in a row with an asterisk, you must subtract one hour. If you end in a column with an asterisk, you must add one hour. For example, during DST if it is noon in GMT, then it is 11pm in Victoria. In 2003, all states except Tasmania begin DST at 2am on October 26, while Tasmania begins its observation on October 5. DST ends on March 28, 2004, in all states.

London is 1 hour ahead of GMT from the last Sunday in March to the last Sunday in October due to DST. New York City is normally 5 hours behind GMT. However, from the first Sunday in April to the last Sunday in October, NYC is only 4 hours behind GMT due to DST.

World Time Zone operates a web page with the current time in each of the australian time zones.
