◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Perth uses the AUD ($) and Ottawa uses the CAD ($). Conversations can stay in English, which is official in both countries. Be careful behind the wheel: Perth drives on the left, Ottawa on the right.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Perth and Ottawa?

Perth is 12 hours behind Ottawa. Perth runs on GMT+8 and Ottawa on GMT-4. 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?

Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).

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 Perth from Ottawa?

About 18,216 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 21h 56m, not counting airport time, winds, or routing around restricted airspace.

Can I send this meeting time as a calendar invite?

Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.

What currency do Perth and Ottawa use?

Perth uses the Australian dollar (AUD, $); Ottawa uses the Canadian dollar (CAD, $). Check the live rate before transferring money or paying with a card abroad — most banks add a 1–3 % FX margin on top of the mid-market rate.

How do I call Perth from Ottawa?

Dial the international prefix used by your carrier (often 011), then +61, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.

What language is spoken in Perth and Ottawa?

Both Australia and Canada count English among their official languages, so business meetings often skip translation. Perth also has no other official tongue; Ottawa adds French.

Do Perth and Ottawa drive on the same side of the road?

No. Australia drives on the left, Canada on the right. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
