The Australia time difference is +11 hours from London and +16 hours from New York in winter, and +9 hours and +14 hours in summer for Sydney (UK and US winter and summer time). The country has 5 time zones: depending on the region and the season, the gap with London ranges from +7 h to +11 h. Because the gap is given here for Sydney, our Sydney travel guide helps you plan your arrival and first days.
In practice, when it is noon in London, it is 23:00 in Sydney during UK winter time (GMT) and 21:00 during British Summer Time. When it is noon in New York, it is 04:00 the next day in Sydney during Eastern Standard Time and 02:00 the next day during Eastern Daylight Time.

The difference of 2 hours between winter and summer comes from the fact that the UK, the US and Australia do not move their clocks forward and back in the same direction or on the same dates.
Watch the transition periods in spring and autumn, when the clocks do not change on the same day in each country: the 2027 table below shows every change in the gap.

Time zones of Australia: gap by region

|---|---|---|---|---|
| Sydney, Melbourne, Canberra, Hobart | UTC+11 / UTC+10 | +11 h / +9 h | +16 h / +14 h | 23:00 / 21:00 |

| Perth | UTC+8 | +8 h / +7 h | +13 h / +12 h | 20:00 / 19:00 |
No local clock change: Brisbane (Queensland), Darwin, Perth. The gap with the other regions of the country therefore varies with the season.
When to call Australia from the UK or the US

Time difference and jet lag: practical tips
Flying to Australia from the UK means travelling east: your day is shortened and you need to go to bed earlier than usual. From North America, the flight crosses the International Date Line and you land on a later calendar day. A few simple rules help you adjust to local time:
- Set your watch and phone to local time as soon as you board.
- Align meals and bedtime with local time from the first day.
- Plan a light first day, with no important meetings or long drives.
- Get out in daylight when you arrive and avoid long naps.
- If you take medication at fixed times, ask your doctor how to adapt the schedule to the time difference.

Jet lag: how flight direction affects you in Australia
- Outbound from the UK (flying east): you « lose » 11 hours in UK winter and 9 hours in summer; your arrival day is shortened and you need to go to bed earlier than your body clock expects.
- Return to the UK (flying west): the opposite applies. Flying west is generally considered easier to cope with: you just need to stay up a little later.
- From New York: the gap is 16 hours in winter (EST) and 14 hours in summer (EDT); you cross the International Date Line and land on a later calendar day, so allow extra time to adjust.
- Your usual night at home (23:00 – 07:00) corresponds to 10:00 – 18:00 in Sydney from London in UK winter (08:00 – 16:00 during BST), and to 15:00 – 23:00 in Sydney from New York during EST (13:00 – 21:00 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in Canberra, the sun rises around 06:04 and sets around 20:21 in mid-January, and around 07:10 and 17:09 in mid-July (table above). After flying east, seek morning light and avoid it late in the day; this is the standard advice for shifting your body clock.
