JC Penny have just released their Black Friday website - they will have the deals on the website until Monday 26th November (Tuesday afternoon in Australia). JCP offer shipping to Australia and you are likely to get your purchases before Christmas.
From experience, popular sizes run out quickly so better to check the deals sooner than later.
Edit: It seems like JCP don't ship to Australia any longer. You can still take advantage of these deals by using a forwarding service like Shipito or MyUS.
