There's no fraud - sellers are allowed to price items at any price point they like, even if you think it is overvalued. The most likely situation is that they do not have stock of these items at the moment, so they put an unrealistic price on them to discourage buyers. When they get new stock, they revert to the proper price. 

If you look at their feedback, you can see the price points of items that were purchased and most of what I looked at was under $1000.

They do have some concerning negative feedback, which would definitely put me off though.

Also, please bear in mind that nobody can offer you a genuine warranty on Ebay, unless they are an authorised distributor. It would be a real shame if you purchased something and after a few months had an issue. These third party sellers have no obligation after the first 30 days, so you would be much better buying from a proper Aussie store and getting a genuine 12+ month Aussie backed warranty. This seller has a "warranty", but after 30 days......well, I would wish you luck in even getting them to respond. Their FAQ's even go against some of Ebay's T&C's.
