It is true that hunters do not want to eradicate. Most deer hunters will leave the old hind because the meat is too tough and she is the breeder. They will take a stag to mount and young ones for meat. Amateur hunters have been used in Victoria with mixed success. Amatuers have also been used to control other pest species. On the Bogong High Plains they have not done well but around Wilson's prom where Hog deer are more prevlent they do better. Certainly deer species that herd are easier than Sambar. Generally speaking though, it is the professional shooter who has done better. More bang for buck. Deer hunters are objecting to the pest classification because there is a threat that their sport will be made harder but then once the deer numbers are down the cowboys and poachers will also disappear.The authorities could always set up something like a ..... "feral animal eradication force" to work in National Parks and State forests. Hunters are not there to eradicate, they are there to pursue the recreational past time of "hunting".
There is no argument for horse lovers that aerial culling is inhumane if they allow it to occur for other pests. I certainly have not heard them complain about this happening. Throw that back at them.
And I am certainly not anti gun. I own guns and shoot pests. I am anti gun lobby who are always in search of relaxing Australia's gun laws and increasing access for hunters in National Parks.
