G'day just re-found this thread. Some areas have had to cull the Koala population and they decided that shooting them was the best method. In a small part of Victoria you can shoot Wombats (no they are not Bats, more like a mobile rocks about 2 feet tall). From time to time, various bird species have an open cull.
If you're not confused, you're not trying hard enough!
When you're confused, I'll try to use smaller words!!!
