Sydney is 5 hours 30 minutes ahead of India during Australian summer time (AEDT, October to April). From April to October, on AEST, Sydney is 4 hours 30 minutes ahead.
The Sydney afternoon is the bridge. From 13:30 to 17:00 in Sydney it is 8:00 to 11:30 in India during AEDT and 9:00 to 12:30 during AEST. That gives three or more comfortable hours where both offices are open. Sydney mornings are too early for India, and India afternoons arrive after Sydney has gone home, so most teams cluster meetings between 14:00 and 16:00 Sydney time.

This pair runs opposite to India and Europe. Sydney moves forward on the first Sunday of October, which was 4 October 2026, and the gap grows to 5h30. It narrows to 4h30 on 4 April 2027 when Sydney returns to AEST.
Cricket fans know this gap well: a Test match starting at 10:30 in Sydney begins at 5:00 in India during the Australian summer. Families with students in Sydney often call at 21:00 Sydney time, which is a relaxed 15:30 or 16:30 in India.
17:30 during AEDT or 16:30 during AEST.
It widens to 5h30 on the first Sunday of October and narrows to 4h30 on the first Sunday of April.
Only from April to October. Brisbane has no DST, so in the Australian summer it is 4h30 ahead of India while Sydney is 5h30 ahead.
