That's a big cat! If they're really getting bigger every generation, then before long other animals such as horses will be in danger as well. I would say address the problem before they get that big! I agree that people should neuter/spay their cats, and this is partly the fault of unresponsible owners that don't, but if there are that many feral cats already, they have to be caught and a fair amount of them euthanized, for our own and our animals safety.
That being said, I'm not an Aussie; I haven't even been their, for that matter (although I'd really love to!), so maybe there is another solution to this problem.
