We certainly don't get the variety you guys get, but we do have a few things that you just don't see in the US - the duncanopsammias, readily available acans etc.
When you look at some of the acros, zoos, rics etc, not to mention some of the prices on fish you get, we get pretty jealous. As an example, I love the Lysmata debelius and ambonensis shrimps - in the US they are what, about $10, here they are about $100 due to the difficulties of obtaining them in Australian waters.
For the most part though, the invertebrate import/export ban works in our favour, otherwise all the good stuff would go to you people where it could fetch higher prices. As an example, after Nemo came out, you could not find blue tangs for ages as they were all going to supply the demand in the US.
One thing that has improved hugely lately is we have some excellent online stores who are getting hold of all of the top line equipment from overseas. Things like Tunze streams that were a great rarity not so long ago, and are now almost standard equipment.
