Here are the pictures of the bandicoot trap. It is a cage about a foot wide and 3 feet long.
The checkerplate is a sliding door which is held up by a hook tied to a piece of string that runs through a pulley and is attached to the wooden pivoting false floor.
Bandicoot smells delicious ham bones at the end of the floor, runs in to suck on those bones, and once past the pivot point, his weight pulls the string which in turn releases the door and voila - he is a banned bandicoot.
Whatever you do, don't try to handle him - he has incredibly strong front paws with digging claws attached. He will rip your arms to shreds. Rather, load the entire contraption into the ute and transport him some considerable distance from your garden. Gold courses tend to be in need of holes.
