No one knows about that. The facts at the moment - No Harley Quinn with Premium, so this is what I'd base my decision on.

Nice, a play on both my name and Australian heritage. You my friend have just made a good pun, and I applaud you.
Continuing with the DLC question, will the extras for the other packs like Harley Quinn and Redhood eventually become DLC for the season pass after an unlock period, or will they have to be separately bought later on, or even be completely collected in a Game of the Year type of way. Trying to decide whether buying the game and pass singularly here may be worth the around extra $10 AUD for the Harley Quinn DLC compared to the premium edition.
If you are unsure thanks anyway. You guys do a good job here.

Hi mate :)

• This game is world wide activation - region free
  
• Keys will be sent out a few days before game release (or earlier depending on pre-load)
• There is no pre-order bonus for the premium edition, and no free DLC

Just wanted to check that this will work in Australia and when the key will be sent out if it is? Also, what pre-order content does it include if you know.
Thanks

The deal will last at least until release :)

wooahh great deal, one cheeky question, how long will this deal stay for, don't have the money for it at the moment but will do in a couple of weeks ?

Yep that will work :)
