Our shared language means Australia seems familiar, but the vast Land Down Under couldn't be more exotic. This is a place where crystal clear waters burst with the colours of tropical fish; where Aboriginal legends ring through the deserts; and where the rainforests are as old as time. Travel from Sydney to the Great Barrier Reef and on to Tasmania, and you'd be forgiven for thinking you'd visited several countries - and that variety is the wonder of Australia. Over recent years Australia has developed a reputation for luxury, with divine hotels in some of the world's most secluded and unspoiled places that have become the envy of the world. Wherever you go - whether exploring the characterful cities, hanging out by the beach, or venturing deep into the wilderness - there are sumptuous hotels that seem to blend effortlessly with the landscape, which must surely be the ultimate luxury.
