Earlier quoted context omitted.
Aussie here, we try to get both the .com and the .com.au (and now also the .au), because people will just use one or the other, regardless of what the link says.
I think opening up .au was criminal. Same as the .uk one. Investor value at the cost of hurting small business by increasing cost or creating confusion.
I've had a .net.au since 1999 and the same rules apply there.
