Chennai is 4.5 hours behind Melbourne
Best overlap: 1:00 PM to 6:00 PM in Melbourne is 8:30 AM to 1:30 PM in Chennai.
If you set up a recurring sync, 1:00 PM to 6:00 PM in Melbourne (8:30 AM to 1:30 PM in Chennai) is the natural home for it. Chennai is 4.5 hours behind Melbourne, leaving about 5 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Because Melbourne and Chennai don't both observe daylight saving, plan to re-check the overlap around March and November.
