The expert was advocating taking advantage of the natural, already adapted fauna in the country. He actually asked why are we farming cattle and sheep when we can hunt 'roo? And part of the irony is that the 'roos are thriving whilst the cattle and sheep are not. The other part of the irony is that the 'roos are in much better shape medically as meat animals than the cattle and sheep. For one thing, being marsupials rather than placental mammals means their parasites think we're 'some kind of weird rock'.

If I'd heard it before I went shopping I think I would have search for for kangaroo meat in the butcher's.
