hmm, in your situation I doubt bridging courses would work for you (but, don't take my word for it, it is highly likely I could be wrong!!)
Best options, as far as I can see, do a course with a low UAI at another uni (I don't think our uni has any that low? Or, once again, perhaps I'm wrong), work your butt off and get nothing but HD's and apply through UAC in September 06.
Or, work for 3 years, earn heaps of moolah, do open foundation and apply as a mature agie.
