Best overlap: 1:00 PM to 6:00 PM in Sydney is 8:30 AM to 1:30 PM in Colombo.
If you set up a recurring sync, 1:00 PM to 6:00 PM in Sydney (8:30 AM to 1:30 PM in Colombo) is the natural home for it. You share roughly 5 hours a day. That's enough for regular meetings, but treat the window as prime time and guard it. Remember that Sydney shifts for daylight saving and Colombo doesn't, so recalculate the overlap after each clock change.
