How Perth works
Perth is spread along the Swan River and the coast, but its core is compact and the public transport is genuinely good. Transperth ties together trains, buses and ferries across the metro area on one fare system, the city centre has a Free Transit Zone and free buses, and there's a train line right to the airport. For most of a Perth visit you won't need a car at all.
Where a car (or a tour) helps is the day trips — the Swan Valley wine region on the city's edge, the Pinnacles desert up the coast, Rottnest Island by ferry, and the South West down to Margaret River. The sections below cover getting around the city and getting out of it.
💳 SmartRider & the free zone
Transperth runs on the SmartRider smartcard — tap on and off for the cheapest fares — and now also accepts contactless bank cards and phones on the network. Fares are zone-based with daily caps, so a busy day of travel never runs up an unlimited bill.

zone
Central Perth rides free. The Free Transit Zone covers the city centre, and the free CAT buses (Central Area Transit) run frequent, colour-coded loops through Perth, plus separate free CAT services in Fremantle and Joondalup. Within the central area you travel for nothing — just hop on. Standard fares with caps apply once you head beyond the zone.
Pick up a SmartRider at the airport, train stations and many newsagents, or simply tap a contactless card for full-fare travel. For a few days in the city, the free zone and CAT buses will cover a surprising amount of your getting around.
🚆 Trains
Transperth's trains are the fast way across the metro area, running from the Perth Underground and Perth stations out along several lines — to Fremantle, Joondalup, Mandurah, Midland, the Airport and the southern suburbs. They're frequent, modern and all on SmartRider.
- Fremantle Line — about 30 minutes from the city to the historic port, and the jumping-off point for Rottnest ferries.
- Airport Line — a direct train to the terminals, around 20 minutes from the city (more under Airport, below).
- Mandurah Line — south down the coast, fast and scenic.
🚌 Buses & the free CAT
Transperth buses cover everywhere the trains don't, on the same SmartRider fares and caps. The stars for visitors are the free CAT buses — Central Area Transit loops that run frequently through the Perth CBD (colour-coded Red, Blue, Yellow, Green and Purple lines), with their own free CAT networks in Fremantle and Joondalup. They're a no-cost, hop-on-hop-off way to get between the city's main sights.
Regular Transperth buses fill in the suburbs and the coast — including services toward the northern beaches and Scarborough — for trips beyond the central free zone.
⛴️ Ferries
Transperth's Swan River ferry crosses between Elizabeth Quay in the city and Mends Street in South Perth — a short, pretty trip that's handy for Perth Zoo and is included in the Transperth fare system. Beyond that, separate commercial ferries run down the river to Fremantle and across to Rottnest Island; those are sightseeing and day-trip services rather than Transperth routes, so book them directly.
🚶 Walking & cycling
Central Perth is flat, sunny and walkable — the CBD, Elizabeth Quay, Kings Park's edge and Northbridge are all within an easy stroll, and the riverfront and foreshore are made for it. Perth is also one of Australia's most bike-friendly cities, with extensive cycle paths along the Swan River and the coast; bike hire is available, and the paths make for a lovely way to see the riverside. For much of a city day, your feet (or a bike) plus the free CAT buses will do the job.
✈️ Perth Airport
Here's where Perth shines: the airport has a train. The Transperth Airport Line runs to Airport Central station, serving the main terminals, with a direct trip into the city in around 20 minutes — fast, cheap and on your SmartRider. Taxis, rideshare and pre-booked transfers also operate from the terminals.
The Airport Line train is the easy, low-cost way into the city. If you're touring beyond Perth afterwards, picking up a hire car at the airport saves doubling back; if you're city-first, take the train in and sort wheels when you head out on day trips.
🚗 Driving & day trips
You won't need a car in central Perth, but it (or a guided tour) opens up the escapes around the city:
| Day trip | Approx. drive |
|---|---|
| Swan Valley wine region | 30 min |
| Fremantle (or 30 min by train) | 30 min |
| Rottnest Island (via Fremantle/Hillarys ferry) | ferry |
| The Pinnacles (Nambung National Park) | 2 hrs |
| Margaret River wine region | 3 hrs |
A few practical notes: Perth has tolls-free freeways but busy peak-hour traffic on the Mitchell and Kwinana freeways, CBD parking is metered and pricey, and country roads beyond the suburbs see kangaroos at dawn and dusk. Car hire is available at the airport and across the city. For the Swan Valley in particular — it's a wine region — a guided tour means no one has to be the designated driver.
