I think that the link you want is this one.
http://www.4x4show.com.au/They do not have the information for the Sydney show as yet and by what I gathered it could be in November.
I went last year but do not remember which month (November ?). They do have good bargains and a lot of things to play with, but last year the prices were not that good.
Here is something that I will post on what happened. I walked in and you would normally start from one place and just walk around. Well as it turned out I missed the first row and found something that I though was good. I asked the price and he told me. I put it down and kept walking. I found another store that had a display buy four for the
X price. Then if you divide that by four it was still more expensive than the single one on offer at the first store that I went to.
So buyer beware.
