Frogs, smaller goannas, snakes. They can climb trees to take baby birds from the nests. This one went fishing in our fish and lily pond, some years ago, and over the course of a week managed to eat every gold fish.
He digs large holes in our lawns searching for burrowing frogs, ankle breakers I call these holes.
Cane toads have now invaded our area in the Kimberley. A large dis-used gravel pit, about a kilometre from our block has become a haven for the toads. I hope that this big old fella does not succumb to the cane toads' poison.
Our block is so far free from the cane toads. About ten years ago we re- fenced our block, replacing the three strands of wire with vermin wire over laid to 90cms with chicken wire (I still bear the fencing scars on my knuckles). The "experts" tell us that the fence will keep the toads out as they cannot climb nor do they jump more than 30 cm high. I am a little sceptical, however I will be pleased to be proven wrong!
