Michael Aspel and the team embark on the show's longest haul ever undertaken, with a visit to Sydney in Australia. The journey is well rewarded as thousands of Roadshow fans turn out with a remarkable array of treasures. Amongst the items under scrutiny are pieces of furniture made by convicts transported to Australia, a part of the keel of Captain Cook's ship Endeavour, and a collection of items belonging to opera star Maria Callas, which receives one of the biggest valuations in Roadshow history.
