‪Australia is as varied as it is enormous-- it is home to thriving cities, vast wilderness, and earnest, friendly people. Sydney is for sophisticates, with its famous opera house and annual Sculpture By the Sea outdoor art exhibits. Port Douglas makes a great base for snorkeling or diving the Great Barrier Reef, and quaint lighthouses keep vigil along the beaches of Byron Bay. Melbourne is a hub of rousing cricket activity, and the limestone pillars of the Pinnacles Desert are a natural wonder.‬
