Time zones in Australia
| City | IANA time zone | Offset in January 2026 | Offset in July 2026 | Daylight saving? |
|---|---|---|---|---|
| Sydney | Australia/Sydney | UTC+11:00 | UTC+10:00 | Yes |
| Melbourne | Australia/Melbourne | UTC+11:00 | UTC+10:00 | Yes |
| Brisbane | Australia/Brisbane | UTC+10:00 | UTC+10:00 | No |
| Perth | Australia/Perth | UTC+08:00 | UTC+08:00 | No |
| Adelaide | Australia/Adelaide | UTC+10:30 | UTC+09:30 | Yes |
The spread across Australia is 3 hours in January — the difference between the easternmost and westernmost zones. That matters when you schedule inside the country: a meeting at 9am in the east can be 6am in the west, and a national broadcast or a train timetable has to pick a time that works across the spread. The table above gives the offset for each city, so you can convert between any two of them.
Daylight saving in Australia
Sydney, Melbourne, Adelaide observe daylight saving; Brisbane, Perth do not. The 2026 dates for the zones that change:
| Time zone | Daylight saving starts 2026 | Daylight saving ends 2026 |
|---|---|---|
| Sydney | Sunday, 4 October 2026 | Sunday, 5 April 2026 |
| Melbourne | Sunday, 4 October 2026 | Sunday, 5 April 2026 |
| Adelaide | Sunday, 4 October 2026 | Sunday, 5 April 2026 |
Brisbane: Queensland does not observe daylight saving, while New South Wales, Victoria and South Australia do. Queenslanders have voted against it three times, most recently in a 1992 referendum — farmers and people in the tropical north argue the extra evening sun would mean more heat, not more usable daylight. Perth: Western Australia does not observe daylight saving. Voters have rejected it in four referendums, most recently in 2009, and the state stays on UTC+8 all year.
What time is it in Australia when it is 12:00 UTC?

How to convert a time to Australia
Take 3pm in London. In January, London is UTC+00:00 and Sydney is UTC+11:00, so 3pm in London is 2:00 am in Sydney. In July, London is UTC+01:00 and Sydney is UTC+10:00, so 3pm in London is 12:00 am in Sydney. The answer changes between January and July, because one or both places move their clocks — always check the offset for the date you care about. The time zone converter does this for any two cities and any date, and the UTC converter converts from UTC.
The best time to call Australia
The overlap of a 9am–5pm working day between Sydney and New York is none in January 2026; between Sydney and London it is none. There is no overlap with either city in a normal working day, so a call has to be early morning or late evening for someone — the kindest time is usually early morning in the city further east.
The time in Australia through the year
The offset of Sydney month by month in 2026 — the local time when it is 12:00 UTC on the 15th of each month:
| Month | UTC offset | Local time at 12:00 UTC |
|---|---|---|
| January | UTC+11:00 | 11:00 pm |
| February | UTC+11:00 | 11:00 pm |
| March | UTC+11:00 | 11:00 pm |
| April | UTC+10:00 | 10:00 pm |
| May | UTC+10:00 | 10:00 pm |
| June | UTC+10:00 | 10:00 pm |
| July | UTC+10:00 | 10:00 pm |
| August | UTC+10:00 | 10:00 pm |
| September | UTC+10:00 | 10:00 pm |
| October | UTC+11:00 | 11:00 pm |
| November | UTC+11:00 | 11:00 pm |
| December | UTC+11:00 | 11:00 pm |
Sydney changes its offset during the year, because it observes daylight saving: the offset moves by one hour at the spring change and back at the autumn change, and the months in between are on the other offset. The table shows exactly which months are on which offset. The world clock for Sydney shows the live time and the offset in effect today.
Australia and the rest of the world
The time difference from Sydney to six major cities, in January and in July 2026:
| City | Difference in January | Difference in July |
|---|---|---|
| New York | 16 hours ahead | 14 hours ahead |
| London | 11 hours ahead | 9 hours ahead |
| Paris | 10 hours ahead | 8 hours ahead |
| Tokyo | 2 hours ahead | 1 hour ahead |
| Sydney | the same time | the same time |
| Dubai | 7 hours ahead | 6 hours ahead |
The differences change between January and July wherever one of the two cities observes daylight saving and the other does not — or wherever they change on different dates. The time zone converter gives the difference for any date, so a conversion done for January is not reused for July without checking.
Calling Australia from London
In January there is no overlap between the working hours of Sydney and London, so any call has to be early morning or late evening for one side. The kindest time is usually early morning in the city further east — 8am there is late evening the previous day in the other city — or late evening in the city further west. The meeting planner shows the overlap for any set of cities.
