Day trip from Perth to Rottnest Island: how to get there and what to do

Rottnest Island sits about 19 km off the coast near Fremantle, and the whole island is only about 11 km long. That scale is why a day trip works: you can arrive mid-morning, cycle or ride the shuttle to a couple of bays, see quokkas, swim, and still catch an afternoon ferry back to Perth.

The trade-off is cost and time. A return ferry plus the island admission fee is a real spend, and the trip eats most of a day. If you have three or more days in Perth, it is one of the best half-to-full-day trips in Western Australia. If you have only one day and want wine country, the Margaret River day trip is the alternative.

Weather decides the experience more than anything else. Summer (December to February) is hot and busy; autumn and spring are the sweet spot. Winter trips are quieter and cheaper but swimming is for the hardy.

Three ferry companies run to Rottnest: Rottnest Express, SeaLink Rottnest Island and Rottnest Fast Ferries. Departures leave from Fremantle, from Perth's Barrack Street Jetty on the Swan River, and from Hillarys Boat Harbour in the north. Fremantle is the shortest crossing; Perth city departures take longer because the boat travels down the river first.

Book online before you travel. Ferries fill up in summer, during school holidays and on long weekends, and the earliest morning departures are the first to sell out. Arrive at the jetty 20–30 minutes before departure, and check whether your ticket includes the island admission fee or whether you pay it separately on arrival.

You can also reach Rottnest by private boat or on a scenic flight from Perth, but for a day trip the ferry is the practical option.

Take the first or second morning ferry so you land before the day-trippers arrive in force. From the settlement, pick up a hired bike or buy a shuttle bus pass, then head out along the sealed roads. The island is small enough that a fit cyclist can reach most of the main bays in a day.

A sensible loop: ride west to The Basin or Longreach Bay for a morning swim, continue to Cape Vlamingh at the western end for the lighthouse and coastal views, then work back via Pinky Beach and the Bathurst Lighthouse in time for the ferry. If you would rather not cycle, the shuttle bus stops at the main bays and the hop-on hop-off pass is the easy option.

Quokkas are most active around the settlement in the late afternoon, and they are wild animals — do not feed them and keep your distance. Pack water, sun protection and food, or eat at the settlement where the main cafés and the general store are.

Budget for the ferry, the island admission fee, and either bike hire or a shuttle pass. Food and drink on the island cost more than on the mainland, so many day-trippers bring lunch. Prices below are 2026 estimates and vary by season and operator.

If you are travelling as a family or group, compare the total against a package that bundles ferry and bike hire — operators often sell these together at a small discount.

For most visitors, no. The day trip covers the main beaches, the lighthouse and the quokkas, and the last ferries back to Perth and Fremantle run in the late afternoon. Staying overnight only makes sense if you want the island at sunrise and sunset, or if you are diving and need more than one day.

Accommodation on the island is limited and books out far ahead in summer, and it is more expensive than equivalent mainland options. If you do stay, the payoff is quiet mornings before the ferries arrive and a night sky with very little light pollution.

Rottnest Island lies about 19 km west of Fremantle, reached by ferry from Fremantle, Perth's Barrack Street Jetty or Hillarys Boat Harbour. The island itself is small — roughly 11 km long and 4.5 km at its widest — and the settlement, main beaches and lighthouse are all reachable by bike or shuttle bus in a day.
