Flinders Chase National Park is South Australia's largest. It became a park as early as 1919, and in the 1920s and 1930s koalas, platypuses, emus and Cape Barren geese from the Bass Strait islands were introduced. The land is mainly sugar gum forest, but the Visitors Center is surrounded by open grasslands where large numbers of kangaroos and geese graze. We tried following the Black Stump walking track in the hope of spotting a platypus. We were warned that getting a glimpse of the creatures requires endless patience, we did our best and saw… nothing but bubbles!
