Best overlap: 8:00 AM to 3:00 PM in Hanoi is 11:00 AM to 6:00 PM in Sydney.
Target 8:00 AM to 3:00 PM in Hanoi, which lands at 11:00 AM to 6:00 PM for the Sydney side. The overlap is wide at 7 hours, so you can protect mornings for deep work and still find plenty of meeting time. Note that Sydney follows daylight saving while Hanoi stays put, so the times above drift by an hour seasonally.
