Is a full week in Perth worthwhile for first-time visitors?

If you hire a car for only part of the week, use those days for harder-to-reach nature stops. Keep central and Fremantle days for walking and public transport.

Balance active days with easy city time. Seasonal weather affects beach and ferry plans, so keep the most exposed outing flexible.

A week gives you room for Perth city, Fremantle, a Rottnest day and slower beach or garden time. Pick a base that suits the majority of days instead of moving hotels for each outing.
