I also have a 2 bedroom unit in Maribyrnong which will be free in Jan, rent is $350 close to shops and public transport, about a 20min drive to the city or work.
As to the question regarding finish times, the college is open from 7am to 7pm with courses starting and finishing between those times, usually rotating every couple of weeks (or for tower guys 7:30-2:30 or 10:00-5:00 generally finding out the friday before). In the first 10 weeks we did work 7am-3pm but can't say if that's the norm (or that you should expect it)
