The Kidds' parents are in trouble once again, and the four siblings must traverse the Australian Outback, recover a pair of stolen gems and defeat treasure-hunting pirates to save them!
The Kidd family is on their way to Australia to find Lasseter's Gold when fellow treasure hunter Charlotte Badger challenges them to a race to the gold! But when the Kidds pull into port in Australia, their parents are suddenly arrested - they've been framed! It turns out Charlotte Badger is a pirate, and she's planted a priceless stolen black opal on the Kidds' ship!
Now Bick, Beck, Storm and Tommy have seven days to traverse the Australian Outback, find Charlotte Badger and her pirate cronies and bring back the evidence that will prove their parents innocent. If they fail, their parents will be found guilty and thrown in prison...forever!
