My next stop was at the town of Mount Gambier,Which sits on the side of volcano. Inside the crater is the Blue Lake where, for reasons scientists are unable to explain, the watern changes color according to the season.After a short visit I contnued down toward the coast.At port Fairy I mat my tour guide,Noel,in the Tower Hill nature reserve."You"ll see many animals if you"re guiet," he said.He was right.I saw koalas,emus and kangaroos.
