Perched on the banks of the wide Swan River, between the Indian Ocean and the sands of the Nullarbour Desert, Perth is one of the world's most isolated cities, yet still boasts an active beach scene and smokin’ nightlife. Family-friendly Cottesloe is brimming with swimmers, surfers and snorkelers. Head north to Scarbourough for a spirited beachside club scene. Coo at cute marsupials on ferry-accessible Rottnest Island, and don’t miss the views from King's Park and Botanic Gardens.

Rawai is an off-the-beaten-path area of Phuket that attracts devotees of Muay Thai martial arts. Training centers here teach all levels, from absolute beginner to world champion. On the opposite end of the vacation spectrum, there’s the Phuket Seashell Museum, an immense collection of delicate specimens from around the world. A visit to the Sea Gypsy Village on the eastern end of Rawai Beach is a transformative experience.
