"Yeah, I think it's an absolute disaster that Australia, the government, allowed kangaroo culling"

Steve Irwin's quote reveals his strong displeasure of the Australian government's decision to enable kangaroo culling. He thinks that it is an absolute catastrophe which it need to not have actually been permitted. He is likely referring to the practice of eliminating kangaroos for their meat and hides, which is a questionable problem in Australia. He likely thinks that the federal government ought to have taken a more gentle technique to handling the kangaroo population, such as relocating them to other locations or providing more resources for them. He likely believes that the government must have taken a more thoughtful technique to the issue, rather than turning to killing the animals. His quote reveals his strong displeasure of the federal government's decision and his belief that it was an error.
