I used the same "toys" that my grandfather and father had, and my sons ans now grandsons are using them. They consisted of a small boomerang and spear for target practise, and a coolamon (carrying dish) to carry them around with. They have lasted at least 5 generations that I know of, so compared to a lot of bought toys, they are doing well.
I did make my sons a go-cart, using old pram wheels and the wood from an old pallet, the only thing that has ever needed changing are the wheels, oh, and quite a few bandages from the occasional spills.
