Cairns is the cheaper trip, by roughly 14% a day — $95–185 against $110–215 mid-range per person. Both are at their best in May, Sep–Oct, so one trip can take in both.

What you'd actually do
A few of each guide's picks, one per category before seconds — the full lists are on the guides themselves.
🇦🇺 Sydney
A harbour city where the commute is a ferry and the beach is on the bus route. Expensive, outdoors-obsessed, and about as easy as long-haul travel gets for an English speaker.
- Sydney Opera House$$The harbour
- Bondi to Coogee walk$Beaches & coast
- Art Gallery of NSW$City & culture
- Blue Mountains$$Day trips
- Manly ferry$The harbour
🇦🇺 Cairns
A small tropical city that exists to get you onto the Great Barrier Reef and into the oldest rainforest on earth. Two World Heritage sites meet here, and almost nothing else in town competes.

- Daintree & Cape Tribulation$$$Rainforest
- Esplanade Lagoon$In town
- Learn to dive$$$The reef

Practicalities
| Sydney | Cairns | |
|---|---|---|
| Language | English, at speed and with heavy abbreviation. 'Arvo' is afternoon, 'servo' a petrol station, 'brekkie' breakfast | English |
| Currency | Australian dollar (A$). Around A$1.52 = $1 in mid-2026 | Australian dollar (A$), around A$1.52 = $1 in mid-2026 |
| Time zone | AEST (UTC+10), AEDT (UTC+11) October–April. Seasons are inverted — December is summer | AEST (UTC+10). Queensland does not observe daylight saving, so it diverges from Sydney in summer |
| Power | 230V, Type I — the angled three-pin plug used only in Australia, New Zealand and a few neighbours. Bring an adapter | 230V, Type I — the angled three-pin Australian plug |
| Tap water | Excellent and safe everywhere | Safe and good |
