Tasmanian sheep farmer Greg Squires became interested in trapping feral cats on his property when he began seeing them “out and about in broad daylight”.
“I figured if we were seeing them out during the day, then there were a lot of them around,” he said.

Duh. They’ve been in their millions and taking tens of millions of native species per year for at least 60 years of recorded sience on the issue.
That is a good question. What is Australia’s total population of feral cats?
And does it exceed Australia’s total population of domestic cats?
Estimates vary widely according to Mr Google.
“3.8 million pet cats in Australia. 0.7 million feral cats in cities.”
Let’s have a look at Legge et al. (2017). It seems to be one of the more reliable sources.
Not sure which paper.
Got it. This one. Legge et al. (2017) “Enumerating a continental-scale threat: How many feral cats are in Australia?”
“The feral cat population in natural environments fluctuates between 1.4 million after continent-wide droughts, to 5.6 million after extensive wet periods. We estimate another 0.7 million feral cats occur in Australia’s highly modified environments (urban areas, rubbish dumps, intensive farms).”
“Feral cat densities are higher on small islands than the mainland, but similar inside and outside conservation land.”
“Mainland cats reach highest densities in arid/semi-arid areas after wet periods.”
“Australian feral cat densities are lower than reported for North America and Europe.”
