1. While it’s rare to see police checks in Western Australia, manned mobile speed cameras are very common, so beware the general speed limit: generally 50kph (31mph) in built-up areas and 110kph (68mph) in rural ones.
2. Take plenty of spare water, food and fuel if you venture out into the bush, and make a note of petrol-station locations.
3. Almost all Perth car-rentals are automatics; if you prefer a manual, make this clear in advance.
