Absolutely, I sold a .com.au domain very recently to a company in Malta. There are legitimate ways in which overseas entities can be entitled to hold a .au domain license, for example a pending or registered Australian trademark.(...)but anyone from anywhere in the world can register an AU if they really want to.
If anyone was serious they'd just register an ABN. I can't imagine there is anyone out there who wants to put $$$s into AU domains and is only being held back by needing an ABN.Yes fair enough...but I'm talking about removing the ABN or Trademark restrictions, which would open up our market to just about anyone, including domainers and speculators.
