With its towering cliffs, mighty blowholes and rough-and-ready 4WD tracks, Dirk Hartog Island off the Gascoyne Coast – the western-most point of Australia – puts the wild back in the Wild West. “People are surprised by how rugged it is,” says Casey Hill from Island Life Adventures, which now offers day tours out of Denham. Stand on a clifftop channelling your inner Chris Hemsworth – some of Thor: Ragnarok was shot here – then wind down with a beach swim before the ferry ride home, when you might spot turtles, rays and the occasional dugong.
