no, in fact you cant register on most international ebay sites unless you have a residential address and a bank account in that country.

however, as an aussie registered seller you can LIST on ebay usa or ebay uk, but please read their terms and conditions and fees first, they are quite different to ebay aussie

It is also better to use your ID that has some credibility showing as opposed to a new ID with zero feedback and item location shown from a different country to the registered.
