The Australian limited edition contains the game, Sebastian's Diary (featuring imagery from the game), and a lenticular art card. The box has a cut-out in the front, using the lenticular card as part of the front cover art.
The game case contains a sheet with a DLC code for The Fighting Chance Pack, a manual, and probably an advertisement for the season pass.
