Since they arrived in Australia with Europeans, cats have unfold throughout 99% of the nation. Only some islands and specifically constructed fenced conservation areas are cat-free.

Who’s accountable?
Success will rely upon focusing and enhancing the already important efforts of governments, Indigenous and non-Indigenous land managers, environmental non-government organisations, business, neighborhood teams, researchers and the general public.
