I have a bank account with Euro Pacific simply to have a place to park money outside of Australia if the case came up that I needed to. I don't actually use it for anything. They have share trading and forex accounts as well, but their fees and commissions aren't as competitive as the companies I already use for these purposes. Very easy account to open considering it's an offshore account.
It isn't really necessary to open a gold account with EP if you're an Australian citizen. Not sure about kiwis as you can just open a depository program account with Perth Mint which is essentially what EP offers with their gold account.
