Hi Hershal,
Can't give you any specific prices but enclosed is a link to a shop near my home. I've bought a bit of stuff from these guys over the years and their prices seem reasonable for what you get down here. They have a big online catalog that includes prices in Aussie pesos so you might be able to find what you need.

Drop me a line if you want me to ring around for any parts in particular. We have a lot of local manufacturers making V8 stuff at good prices.
Cheers
