It sounds like the numbers they're dealing with may be well beyond what could be controlled by cats. Additionally, they may be wary, as Australia is already a case study in what can happen as a result of introducing one species to control another's population: https://en.wikipedia.org/wiki/Cane_toads_in_Australia

No, that's the beautiful part. When wintertime rolls around, the gorillas simply freeze to death.

I once had a cat that lived in a work shed. Almost every day he brought me something dead. I hear you but it was just the logical thought to come to mind that I wondered why individuals didn’t have cats, or what the cats were doing. Granted now I’ve got a cat that can’t be bothered to even chase something, she just ..looks at it.

Haha, yeah, fair. I imagine the cats that do live there are probably enjoying themselves through this but have had their capacity overwhelmed.

I was about to say... shouldn't the cane toads take care of that?

There are probably millions of feral cats roaming australia.
