While most animals that are pests in Australia and New Zealand are non-native species, not all pest animals are introduced. Some native species such as kangaroos and some parrots are considered to cause significant economic or environmental damage. Ironically, many Australian animals have been released in New Zealand and some, like the brush-tailed possum, have become a serious pest.
