Sydney uses Australian Eastern Time: AEST (UTC+10) from April to October and AEDT (UTC+11) during daylight saving time from October to April. Because it is in the southern hemisphere, Sydney’s summer time runs during the northern winter.

Daylight saving in New South Wales
Clocks go forward on the first Sunday of October and back on the first Sunday of April. Queensland does not use daylight saving time, so from October to April Sydney is an hour ahead of Brisbane.
The gap to London swings between 9 and 11 hours during the year, because the two cities change their clocks in opposite seasons.
Business hours and the ASX
The Australian Securities Exchange trades from 10:00 to 16:00 Sydney time. Sydney is one of the first major financial centres to open each week, while it is still Sunday afternoon in New York.
