The only items that Australian Customs would restrict export of are coins of "national cultural significance" - the technical definition of which is: it has to be of significance to Australia (ie either made here or used here), it has to be worth over AU$15,000 and Australian museums don't own at least two similar specimens. They're not illegal to export, but there is a permit the seller would have to obtain to export them, and the seller would probably forward the cost of the permit on to you. If the seller knows what they're doing, they would know about this and tell you in advance of your agreeing to purchase.
So as long as you're only buying cheap common stuff or modern Australian mint products and not holey dollars, Adelaide pounds, old banknotes or similar items, you should be OK.
Importing the coins into America is the second half of the transaction. The only US import restrictions for coins that I'm aware of are that if the coins are ancient coins from Cyprus or China, or if they're modern bullion coins from Cuba, Iran or Sudan, they're illegal for you to import. I don't believe there are any import duties on coins if the total value of the package being imported is below US$10,000, but a local would be able to confirm this better than I.
