Perth is an easy, unhurried city to get around, with a tidy public network, a genuinely useful set of free buses, and — good news for arrivals — a train straight from the airport. Before the details, two things smooth a first trip: a travel eSIM so timetables and maps work on arrival, and, if you’d rather your first airport run was handled, a pre-booked private pickup.
The free CAT buses
The nicest quirk first: the CAT (Central Area Transit) buses are free, looping the Perth CBD on several colour-coded routes, and there are free CAT services in Fremantle and Joondalup too. For a lot of central sightseeing you can simply hop on and off at no cost. It’s the first thing I’d use.
SmartRider, for the rest
Beyond the free buses, Perth runs on Transperth — trains, buses, and ferries — and you tap a SmartRider card to use them. Buy and top up one at stations and newsagents; it’s cheaper than paper tickets and covers the whole network with fare zones based on distance. Tap on and off; the system handles the fare.
Trains and the airport
The train network is clean and quick, radiating from the city to the suburbs, the coast, and Fremantle. Best of all, the Airport Line now connects Perth Airport directly to the CBD in around 20 minutes — a recent and very welcome addition — with taxis, rideshare, or a booked private airport pickup as alternatives. The train to Fremantle is one you’ll likely use; it’s a straightforward ride from the centre.
Ferries and getting to Rottnest
Transperth ferries cross the Swan River from Elizabeth Quay to South Perth — handy for the zoo and a pleasant short trip in itself. For Rottnest Island, the region’s headline day out, you take a dedicated ferry (from Fremantle, Perth, or Hillarys); many visitors book a ferry-and-bike or tour package to keep the logistics simple.
A simple mental model
Hold this: free CAT buses in the city and Freo, a SmartRider for the wider network, the Airport Line to and from the plane, and a dedicated ferry for Rottnest. Get connected with an eSIM, grab a SmartRider, and enjoy how much of central Perth and Fremantle you can see for free.
