Monitor lizards in the glass house mountains

We went for a hike around mount Tibrogargan on Monday and we saw 5 or 6 different monitor lizards (they call'em Goannas here). Some were shy and scurried off to climb trees as soon as they spotted us. Others didn't really care, as long as we stayed a couple of meters away. Here's a BIG one (~1.5m) foraging for food around the staging area.
