We have koalas in our trees, they moved on for some reason, now all the trees are coming back and looking much better.
Got a mate who used to work in the DSE. They used to go on Kwala culls coz they were killing tons of trees. Had to be kept all hush hush coz if it got out the sheite woulda hit the fan.
The Kwalas are nice, but they do make things look grim when they eat out all the trees.
