"Henry, Penny, Frankie, Mum and Dad embark on their most exciting adventure yet - from Tassie to the very tip of the Top End. Travel with them on the ferry across Bass Strait to the mainland, through Kelly country, along the Murray, into the Flinders Ranges, underground at Coober Pedy, overhead at the Olgas, overland to the Great Sandy Desert, with the fishes at the Great Barrier Reef, deep into the Daintree, out to the islands, kayaking at Kakadu and finally frolicking on the beach at the very top."--Publisher description.
