So what happened when you picked up the telephone and called Apple? What did they say when you explained the situation to them? It's pretty obvious this is the result of a goof, nobody in their right mind would think that Apple's online store wasn't authorized to sell Apple equipment.
The au part is likely related to the support center your question was handled by. It's logical that a question from Taiwan might be handled in Australia. You don't think they staff a support center in every single country do you?
