Recommended meeting window
You have a 5.0-hour window of overlapping business hours each weekday: roughly 09:00 to 14:00 in the first city. Pick a slot near the centre of that window to give both sides time to settle in and to handle follow-ups.
If you need to set a recurring meeting, anchor it on the calendar of whichever side the meeting matters more to and let the other side's invite render in their local zone. As long as both calendars store the meeting against an IANA identifier (which all modern calendar apps do by default) the meeting will follow daylight saving correctly without you needing to adjust it twice a year.
For one-off interviews, sales calls or external customer meetings, default to a slot that is firmly inside Ho Chi Minh City's 10:00–16:00 working window — the deeper interior of the day reads as polite in nearly every business culture, and gives you buffer if a previous meeting overruns.

Background on these two zones
Ho Chi Minh City sits in the Asia/Ho_Chi_Minh IANA zone, currently at UTC+07:00. Sydney sits in Australia/Sydney, currently at UTC+10:00. The current difference of 3 hours ahead of reflects whichever side, if any, is currently observing daylight saving time. If one side enters or leaves daylight saving while the other does not, the gap between the two cities will shift by exactly one hour — usually for several months.
You can read more about the rules behind those transitions on the dedicated zone pages: Asia/Ho_Chi_Minh and Australia/Sydney. The daylight saving survival guide explains how to keep recurring cross-border meetings from drifting twice a year.
