☼ Where this stands
Four rough routes for a trip with the grandparents, who are 90 — in a shoulder season, not too hot. With travellers of 90, a nonstop flight isn't a bonus, it's the plan, and that settles the airport. Pick a route and a length, and it becomes a full guide like Italy.
✈ Getting there · nonstops only
| Route | Nonstop? |
|---|---|
| YVR → Sydney | Yes. Air Canada daily, year-round, plus Qantas about 4× a week. About 15½ hours. |
| YVR → Brisbane | Yes. Air Canada, about 6× a week as of autumn 2026 — check it runs on your dates. |
| YVR → Melbourne | Not at the moment. Connect via Sydney, a 1½-hour domestic hop. |
| SEA → Australia | No nonstops. You'd connect via Los Angeles, San Francisco or Vancouver. |
Leave from Vancouver, even if the grandparents live nearer Seattle: a 2½–3-hour drive to YVR is far easier than a connection either side of a fifteen-hour flight. Checked October 2026; schedules change.
☼ When “not too hot” means
The seasons are flipped, and the north and south want different months.
- South — Sydney, Melbourne, Tasmania: March–April or October–November, roughly 18–25°C. Avoid December–February, when heatwaves can reach 40°C.
- North — Queensland, the reef, Uluru: May–September, the dry winter, roughly 20–28°C.
- Both in one trip: late April–May, or September to early October.
① Sydney, from one base
The easy one
WhenOctober–November or March–April
FlightsYVR ⇄ Sydney, nonstop both ways
Shape10–14 nights in one harbourside hotel, around Circular Quay or The Rocks · harbour ferries to Manly and Watsons Bay · the Opera House and the Royal Botanic Garden · the Blue Mountains and a Hunter Valley lunch as day trips with a driver
At 90No internal flights, one unpack, and nearly everything reachable by ferry or car.
② Sydney and Melbourne
Two cities, one short hop — Tasmania if you like
WhenMarch–April, or November
FlightsIn and out of Sydney, plus a short flight to Melbourne
ShapeSydney 5 · Melbourne 5 — free trams in the city centre, the food markets, a Yarra Valley day, the Great Ocean Road with a driver · optionally Hobart 3, for MONA by ferry and Salamanca Market
At 90Two or three bases, short flights, and two of the most tram-friendly, walkable cities in the country.
③ Queensland in the dry season
Warm, not hot — and the reef without swimming
WhenMay–September
FlightsYVR → Brisbane nonstop; home the same way, or via Sydney
ShapeBrisbane 3 — river ferries, koalas at Lone Pine · fly to Cairns · Port Douglas 5–6 · the Great Barrier Reef by a large, stable pontoon boat with semi-submersible and glass-bottom options · the Kuranda railway up and the Skyrail cable car down · a Daintree river cruise
At 90Everything by boat, train or car, and the dry season avoids both the humidity and the stinger-jellyfish months.
④ Sydney, Uluru, Melbourne
The icons, paced slowly
WhenLate April–May or September only — Uluru is harsh outside that window
FlightsIn and out of Sydney, plus two domestic flights
ShapeSydney 5 · Uluru 2–3 — drive-up sunrise and sunset viewing areas, the Field of Light · Melbourne or Adelaide 4
At 90The most ambitious of the four, with three flights and some early starts — but seeing Uluru takes far less walking than people expect.
⚑ Travelling at 90 — settle these first
Travel insurance is the real gatekeeper. Many insurers stop at 80–85; specialist cover exists but needs medical declarations. Sort it before booking anything non-refundable.
Premium economy or business, nonstop, and book airport wheelchair assistance at both ends, even if they won't use it for everything.
A quiet first day. You lose a calendar day flying out and the clocks are 17–19 hours ahead, so plan nothing for day one.
Entry: Canadians and Americans need an ETA, an electronic visa applied for in the official AustraliaETA app — quick, about AUD 20.
Fewer moves. Hotels with lifts and private drivers for day trips; every hotel change costs more at 90 than it looks.
☼ Another idea, for later
Australia's long-distance luxury trains — The Ghan and the Indian Pacific — or a small coastal cruise. You unpack once and the scenery comes to you, which often suits travellers of 90 best.
