Yes some people have no respect and obviously don't have the brains to seek out their own area to detect. A couple of years back I went out to a 185ha patch of vacant crown land. I found one little nugget then quickly moved on a hundred metres or so and found another. As I was carefully covering my dighole I glanced up so see a Hilux hidden behind a bush. The moment I moved off another hundred metres he pounced on the spot I'd just left. I went on finding random small nuggets because all I was doing was looking at the viability of this block for dryblowing.
That afternoon I pegged the block P20/2485 and within a week the areas of native vegetation had vehicle tracks everywhere. The guy must have had a bunch of mates, perhaps the seasonal nomads from the caravan park. I never went back with the metal detector but the block in question has had four parties peg it. I pulled out as it was not worth fighting over.
A poacher by the name of Lester from Toodyay is just like those guys with the detectors. He jumps on ground others have pegged and objects to their pegging through the warden's court. He doesn't have what it takes to choose his own patch of dirt. The fight for that lease is still going on but I don't think Lester is going to win. He's upset too many people so his days are numbered.
