Phnom Penh×Perth
Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Phnom Penh uses the KHR (៛) and Perth uses the AUD ($). Language shifts too — Khmer in Phnom Penh, English in Perth. Be careful behind the wheel: Phnom Penh drives on the right, Perth on the left.

Quick answers. Before you book the call.
What's the time difference between Phnom Penh and Perth?
Phnom Penh is 1 hour ahead of Perth. Phnom Penh runs on GMT+7 and Perth on GMT+8. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
There are 7 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
How far is Phnom Penh from Perth?
About 4,976 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 6h 21m, not counting airport time, winds, or routing around restricted airspace.
