JB Hifi in Bourke St, Melbourne. They are not on their online store, but I was in that store a week ago and to my surprise, there they were, three copies of each, sitting in the shelves.
So my advice is, if you haven't already done it, ring the main store and get them to look on the shelf. If they don't have it, they may still be able to check if they're in stock in another branch. JB have been becoming super expensive for me but these were $52.99 each, which is not that much higher than Am Au (though as mentioned, I initially 'obtained' them at a better price than Am Au have now, however I no longer trust I will actually see them.)
Failing this, my other suggestion is to go with Rarewaves.com. They still have copies. With deliv, you only end up paying slightly higher than JB, and you get points towards a later discount coupon.
I hope some of this helps.
