Nomad might be the only Australian dealers but they haven't had them in a long time & can't get them (for some reason i do not know).
How many are you looking for Neale?
Without being rude in GT fishing $500 worth of lures is not much at all, & if you were to get $500 worth of a lure like an Orion well hey they are worth every penny, you should get around 7 lures for that price including postage.
Someone mentioned a while ago that a shop n Melb was selling a Hammerhead Shakur for $199, now that's for 1 lure, just spend the $500 & you will not regret it, great lure that is very tough & will last, & can be quite hard to get at times.
