Adelaide to Sydney: the time difference

On 2026-10-05 at 9:00 AM in Adelaide, it is 9:30 AM in Sydney (Monday, October 5, 2026). Sydney is 30 minutes ahead of Adelaide.

Adelaide has a half-hour base offset and observes a southern-hemisphere clock change. It differs from both Perth and Sydney, even though all three cities are in Australia. Sydney’s summer is the northern hemisphere’s winter. Its daylight-saving changes can move in the opposite direction from those in North America, making a single year-round difference unreliable.
