Worldwide, there have been reports of bugs in the game (why did it have to be bugs?!), but recently in Australia there have been some complaints, the most predominant being the dramatic rise of the Steam price from $49.95 to $89.95 to match the retail cost in-store.
The most recent issue, however, has been with regards to the pre-order DLC codes that came with the game. Fallout: New Vegas went onsale a day earlier than the US, which has resulted in problems with the codes not redeeming. However, we've just received an update from Bethesda stating that anyone in Australia or New Zealand with a pre-order code for DLC will be able to download the content any time after 10am AEDT. Good news at last!
More updates as we get them.
