MS changed the way drivers are installed in Vista, which breaks backward compatibility. The Starforce copy protection drivers will not install properly, preventing the game from running.
If you change the language in the registry to 'English', it should allow you to install the 1.49 North American / UK English patch, which removes copy protection. Other than a different version of Starforce, I wouldn't expect the Australian publishers to have made a lot of changes to the game itself, so hopefully there shouldn't be any problems with this (several people have installed the English patch over other localizations, in a partly-successful effort to switch languages).
There is a download and description of a reg file in
this topic to change the language, though it sounds like you wouldn't have a problem doing it manually.
Lady Rain describes how to install BD under Vista in a reply in the
Patch 1.49 topic.
I don't know if the Australian BD publisher has any plans to release an updated patch to remove the copy protection, but I would guess not, if they haven't done so by now.
