I still can't figure out why all the big internet stores are blocking Australia because of a tax collection. I'm fairly certain that in the USA if you live in a State that has an Amazon warehouse, you have to pay local sales tax.

Also, my wife sells things on Etsy, and they are also thinking of blocking Australia, but when she sells things to people in England, on the invoice it has listed a VAT collected amount paid for by they buyer.

I'm just confused as to what the Australian Government is doing differently to everywhere else that already mandates collection of taxes and duties and such, that has pissed off the retailers so much that they are refusing to deal with Australian customers.
