Just a zippy 30-minute ferry ride from Fremantle (or 90 minutes from the Perth CBD), Rottnest Island is one of Western Australia's greatest gems. Also known by its local Aboriginal name, Wadjemup, and ‘Rotto’ by locals, it’s an essential addition to any WA weekender itinerary. Out-of-towners may know Rottnest for its friendly population of quokkas, but the island is also home to the most incredible azure blue waters you’ll come across, and nowadays, it has a selection of top-notch eateries and luxe accommodation, as well as camping grounds, cafés and low-key restaurants for the budget-conscious.
Good for: Families, leisure-lovers, nature-fans and anyone who likes looking at eye-wateringly blue water.
