The Australian Classification Board seems to have outed a Game of the Year Edition of Dishonored, which would likely include all of the DLC released for the game, including The Brigmore Witches, which is due later this month.
The game was also rated MA15+, not R18+, and marked “Modified”, meaning the game was changed. So, the Aussie version of the GOTY Edition will likely be altered for content, though the Board itself has not responded to queries about what’s different in the game.
Stay tuned for confirmation from Bethesda in the near future.
