There's a button at the top of each forum to start a new thread there. You can't start one in this area because you signed up for the forum and only 'guests' can start threads here. (Edit: or at least that was my understanding of the intention) In this case you would have been better off starting a new thread in the Sales Support area.
To answer your question you get the choice of plug type when you order, and that does include Australian type plugs.
