Day 77 - After arranging accomodation for later that week we walked back to Reef HQ and saw the bits we missed before as well as revisiting tree frogs, seahorses, sharks and other fish and seeeing a man in scuba gear scooping up baby fish from the main tank. Nearby the Aboriginal Cultural Centre had interesting information on the history and treatment of Indigenous Australians and a gallery of their traditional art works. On our way back the Perc Tucker Regional Gallery had mostly contemporary portraits by various artists but was good for a quick look round. We retrieved our bags from Civic Guest House and walked up to the Marina where we caught our first greyhound bus - Olivia sat by a man who talked to himself and Catherine next to a nice American guy who gave her fruity chewing gum as we watched National Treasure.
