Just a little aside to this, talking about early European contact with our land, in the Wentworth Museum (NSW/Vic border) you will find a tree stump that was removed from under the stump of a river red gum (yes these mighty trees often grow on the stumps of previous tree's) at the banks of the mouth of the Darling river in the late 70's, the interesting thing about this tree stump is that the tree it once belonged to was cut down with an axe, you can clearly see the axe marks, something the aboriginals didnt do, it could only have been someone from Europe, big deal you say, well the tree that it was found under was aged (you can count the rings for yourself from a slab sample) and started it's life around 1700, that means that someone cut the origional tree down with an axe before 1700 and at wentworth, hundreds of Klm's up the Murray river, go figure. Proof that someone settled here and explored inland around 100 years before previously thought?
