Will the DLC work?

I want to buy the Borderlands 2 GOTY edition from here, http://www.amazon.com/Borderlands-2-Game-Edition-Playstation-3/dp/B00ERDGMO4/ref=cm_cr_pr_product_top, but I live in Australia and worry that it is American.
All I want is the DLC, I have the game, so will the DLC disk work with an Australian PSN account.
And by the way, I am using a PS3 I bought from England UK.

My opinion would be that it will not work since this particular version of the game and dlc’s were mainly for distribution in North America and South America. There might very well be a different one for AU. Fortunately, I am in the US so I took advantage of this great deal but as good of a deal as it looks, if it doesn’t work you just lost $20USD. Also too all the games have this code on the side sleeve and this version reads BLUS 82001. You might get a more accurate answer by sending an email to admin@2kgames.com.au and give them the code. Good luck!
