In a recent case, our team spent a week in the Victorian High Country.
We were there to watch a man who was supposedly hunting, fishing, and 4WDriving. In reality, it was staying in a cattleman's hut with a woman who he had collected on the way.
We were able to provide a range of photographs and videos of the two of them, using camouflaged cameras hidden near and inside the hut, a digital night vision device, a camera lens almost a foot long, and a ghillie suit, among other things.
It was cold, and a little damp, but a lovely place to spend days sitting motionless while wallabies, deer and other animals went past our hide, so close we could almost touch them.
We understand the marriage in question has now ended.
