Are you sure? Doing some googling landed me on the Australian Border Force's website with this:
Collectable coins
Collectors of coins consisting of gold, silver and platinum trade coins at prices determined by their rarity, condition and beauty. Collectors may acquire coins for investment purposes but they are not precious metal coins in an investment form. Importing coins with a value of
more than AUD1000 is subject to assessment for GST but no duty applies.

I have no experience in this but would love to know if you can get 22 Karat Gold US Eagles without paying GST.
Seeing as though they have US dollar face value does anyone know if you can bring it in as a foreign currency instead of a manufactured product incurring GST.
