This Amanita, of which I can't give you a species name for, is a mycorrizal fungus thereby assisting the nearby trees. Did you notice the types of tree that may be associated with it?
It is near the previously identified Horse Dung Fungus so has two large gum trees, a Grevillea, a few succulents, a wattle and a droopy bush with bottle-brush-like flowers that we have a good deal of and I should get someone at the Atlas of Life to identify for me!
