Clones & Drones + D3:Africa no longer avaliable in Australian Steam Store

After the Australian store switched to listing game prices in AUD instead of USD, Clones & Drones, and Democracy 3: Africa are no longer available for purchase. Clones and drones can be purchased as part of the Democracy 3: Collectors Edition bundle, but not individually. I would like to purchase the DLC, but I do not wish to buy the collectors edition as I already own the base game and some of the other DLC.
