Australia has some great trees, the Karri forests in Western Australia and the giant Tasmanian hardwoods http://www.gianttrees.com.au are truly world class.
I have a soft spot for Australian gum trees though and luckily there are a number of great specimens not far from home. They remind me of the struggle to live through the hard life this country can deliver. They twist and turn and discard unwanted pieces but they struggle and survive in adversity.
On this page i will try to show the beauty of some of the ones I have come across locally, Clearly there are some impostors though with a couple of these pictures showing other varieties of trees.
