1.shooting is oppertunistic and not a control method.

2.the reason the dog problem is out of control here in WA is because when the APB handed over aerial baiting to the pastoralists they sat on there hands and did nothing untill the dogs were once again out of control..
3. the reason I know this is because I worked for the APB in the 70's and 80's involved in both noxious weed control and vertebrate pest control.
After moving to QLD I owned and opperated a licensed weed spraying buisness.DPI licensed.
I also spent 12 months at Roma doing parthinium control work for Stock routes and Rural Lands Protection Board.

Mal Ferguson is a good mate of mine.
Does his name ring a bell.
