Jump on pro brewer forum, it's U.S based but pretty good.
Depending on the size you are looking at there are a few companies here in oz but their websites don't do themselves much justice.
Smaller size say up to 200L I would look at core brewing concepts pilot brewery, over that there is premier stainless, dme, and others I can't think of off the top of my head.
But for websites all are very vague.
