This one was taken just hours ago by my 9 year old son using my old Canon 40D camera. These mushrooms grow in symbiosis with some very large pine trees which are not native to Australia. If anybody knows which species this is please post its name here.

Sure looks like Amanita muscaria to me, though I’m no expert. You can find photos for comparison along with accounts of its introduction to your area in Wikipedia. Fine photo by the way, and compliments to your son!
I agree with Hank’s id. By the way, I believe they are quite poisonous.
This is indeed an A. muscaria. It is highly toxic.
