Cost GuidesHow Much Does a Family Trip to Perth & Western Australia Cost in 2026?
Perth and the south-west corner of WA is the "no passport needed" family adventure most East Coast Aussies have never done. Car-free Rottnest Island with quokkas, Margaret River's kid-friendly caves and family wineries, Busselton's 1.8km jetty with an underwater observatory, and Perth's own Kings Park + Cottesloe sunsets over the Indian Ocean (the only AU state where the sun sets over the sea).
Saving for this trip?
Start planning freeThe short answer: budget AU$8,000–10,000 all-in for a family of four on a 10-night WA trip with Perth, Rottnest, Margaret River, and Busselton, flights included. The SaveToRoam template seeds AUD 8,252 — accommodation, flights, activities + local transport (ferry, hire car, bike hire), and daily food budget — cheaper than every overseas Pacific template, comparable to a Queensland domestic trip, and it's fully domestic (no passports, no currency conversion, no travel insurance headaches).
Once the destination cost is clear, the next step is turning it into a plan. Use the family holiday budget template to organise the cost lines, the weekly savings target guide to work out what this trip means per week, and the trip savings platform guide to keep the itinerary and savings plan connected as prices change.

The Trip Outline: 10 Nights, Four Stops
- Perth, 3 nights — arrival base. Kings Park + Botanic Garden, Elizabeth Quay, Cottesloe Beach, Perth Zoo, Swan River cruise, Fremantle Markets day trip.
- Rottnest Island, 2 nights — ferry from Fremantle (30 min). Car-free island, cycle-only transport. Quokka photos (yes, at Parker Point), 63 beaches to choose from, snorkelling at Little Salmon Bay, the Wadjemup Lighthouse.
- Margaret River, 3 nights — drive south (3h). Family-friendly caves (Lake Cave, Jewel Cave), surf beaches, Margaret River Chocolate Company, Lavender Estate, family wineries with playgrounds (Voyager, Xanadu).
- Busselton, 2 nights — drive back north (1h). Busselton Jetty + Underwater Observatory, Geographe Bay swimming beaches, whale watching (June–Dec), CinefestOz town buzz.
Why this order: PER is the arrival gateway. Rottnest off the start when energy is high (cycling). Margaret River for the driving-depth middle leg. Busselton as the relaxed wind-down before the return flight — the Jetty + beach combo is perfect for a final "holiday holiday" day.

Total All-In Cost
| Line | AUD | Auto-seeded? |
|---|---|---|
| Flights (east coast mid-shoulder, family of 4) | 2,200 | ✓ Template |
| Accommodation 10 nights | 2,880 | ✓ Template |
| Daily budget 10 days × AUD 160/family | 1,600 | ✓ Template |
| Activities + local transport bundled (ferry, hire car, bike hire, Zoo, Jetty, Cave + more) | 1,572 | ✓ Template |
| SaveToRoam template total (auto-seeded) | 8,252 | |
| Petrol buffer + souvenirs | 250 | + Add yourself |
| Mid-range all-in shoulder total | ~8,500 | |
| Peak (AU school hols Dec–Jan + Easter) | ~10,500 |
AUD 8,252 is what the template seeds automatically — accommodation, flights, bundled activities + transport, and food. Add the buffer items yourself. Shoulder-season peak pushes to ~AU$10,500 driven by Rottnest doubling and Margaret River doubling during long weekends.
When to Go
| Season | Month | Weather Perth | Crowds | Cost |
|---|---|---|---|---|
| Spring | Sep–Nov | 18–26°C, wildflowers | LOW–MED | MED |
| Summer | Dec–Feb | 28–38°C, dry | HIGH (school hols) | HIGH |
| Autumn | Mar–May | 20–28°C, sunny | MED | MED |
| Winter | Jun–Aug | 12–20°C, some rain | LOW | LOW |
Best AU school-holiday windows: April (Easter) and September/October. WA wildflowers explode Aug–Oct — a genuinely unique Australian natural phenomenon most east-coasters never see. December/January summer school holidays: great weather, peak prices, Rottnest ferries book out — reserve 90+ days ahead. June/July winter: quokkas and Rottnest cheaper but cooler swimming. Whale watching June–December at Busselton is exceptional.
Why Perth/WA Beats Queensland for a Family Domestic Trip
Compared to Cairns/FNQ (~AU$7,500) or Gold Coast (~AU$6,500):
- Longer trip for similar money — 10 nights here vs 7 nights Cairns
- Unique to WA — quokkas, wildflowers, Indian Ocean sunsets — nothing on the east coast compares
- Fewer tourists — genuinely less crowded than Queensland coastal destinations
- Car-free Rottnest — unique family experience, impossible to replicate
- Family-friendly wineries — Margaret River does it in a way Hunter Valley doesn't
Where east-coast AU trips win:
- Shorter flights from SYD/MEL/BNE (3h vs 4h 30m+)
- Reef access (Cairns, Whitsundays)
- Theme parks (Gold Coast)
- Warmer winters
Pick Perth/WA if the priority is unique Australian experiences + longer trip + beaches without crowds. Pick Queensland if reefs or theme parks drive the trip.
