That's huge. I would have thought the bigger ones would all be in QLD. Pilbara is pretty dry and arid. My cousin's just outside of Darwin and some of the people he knows go out pigging with dogs, and just a knife. One guy who does it goes barefoot with a Bowie knife.
I've never met a normal person with an interest in it. 
I used to want to go shooting for them until finding out you can't eat them.
