I think you should be able to work...i know of others that do. The UWA for 12 wks is full on...you would only want to work on Sat am and maybe 1 or 2 nights for 4 hrs or so i would say.
Not sure about the curtin course...you should be able to manage.
when looking at the options, don't forget to add accomodation costs and cost of living into the equation!
Cheers
