So as I said, I will be posting wildlife pictures from my recent Australian adventure on a weekly basis. We begin with that most obvious of Australian critters - the koala. Unfortunately, we never managed to see one of these in the wild so these photos come from the Healesville Sanctuary and the Featherdale Wildlife Park, both superb collections of native species in generous enclosures.
