Rickster....some governments are not as apt to intervene in people's lives like the US Federal Government. The major problem in Oz as I understand it....besides the women wanting to stand at the bar nowadays...is all the "imported" species that have no natural predators. Guam has almost lost all of the birds due to snakes showing up in freight shipments....New Zealand has its problems as well...as does Hawaii. Even the USA is beginning to have problems....Fire Ants, Killer Bees, mussels, aquatic plants, Kudzu.....the list goes on.
The hunt as described must be a giggle....stalking the dangerous wild pussy...doing in the cornered Opossum...participating in the Barbied Boar.....hunting the wily enviromentalist!
