Part time makes it difficult. If you find a good instructor (pm me if you want a brilliant one based in melbourne but not MB) then try this:-
1. make sure the a/c & instructor are IFR
2. jump in, fly north VFR or IFR
3. do your 10 hours over 2 nights - spend the money on a motel in Bendigo or wherever
4. fly back and hope that the weather is ok the next night for your test
Worked a treat - we were able to legally fly VMC in non-NVFR forecast conditions until north of the divide after which all was hunky-dory. By having the instructor with you during the 'day off', you'll cover all of the theory - even better if you can take a laptop and practice ADF/VOR tracking/intercepts during the day.
