I don't know what the situation is these days, but many years ago, the Royal Aero Club at YBSK offerred a 3-weeks course for what used to be called a PPL (Restricted). That gave you the basic licence, including theory exams, but not the navigation component. Any current instructors out there who can provide the current situation?
I doubt that PPL exams can be taken outside of Oz, but I've been out of the loop with Oz rules for a lot of years.
