Australia is home to a number of regions and ecosystems—and we try to visit them all! From Western Australia's underwater realm, to the Outback's Kimberley, to the magnificent Great Barrier Reef, we discover iconic wildlife—think massive saltwater crocs, the elusive rock wallaby, and countless marine animals—ride off into the sunset on desert-scapes dotted with bizarre boab trees, and explore by boat, Zodiac, helicopter, and rugged, all-terrain vehicle. Our Australia tours are comprehensive, expanding your world with every new experience, so we’ll fly over Mitchell Falls, cruise along Montgomery Reef, and venture to Horizontal Falls, which actually reverse as the tide turns. We'll snorkel and dive daily in the Great Barrier Reef, home to over 600 types of soft and hard coral and is home to 100 species of jellyfish, 3,000 varieties of mollusks, 1,625 types of fish, 133 varieties of sharks and rays, and over 30 species of whales and dolphins. No matter where you join us in Australia, you'll have an unforgettable expedition.
