Why people convert Thailand to Melbourne time
- Scheduling a call from Thailand to Melbourne: a 10:00 AM start in Thailand lands at 1:00 PM in Melbourne, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Thailand and Melbourne are inside the 9-to-5 working day between 9:00 AM and 2:00 PM ICT time (12:00 PM–5:00 PM AEST). That is roughly 5 hours of usable overlap.
- Coordinating a Thailand-based team with Melbourne contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a +3h gap is not.
- Block 9:00 AM–2:00 PM ICT as the recurring meeting window if you work primarily from Thailand and need Melbourne colleagues present.
- Melbourne: Clocks spring forward on Sat, Oct 3, 2026. Any meeting series spanning that date will shift by an hour in local time.
