Dunno, but I always wondered why Parra doesnt have lockers....gosh, my bag can get heavy sometimes. Then again, heaps of people drive so they just put their books in their cars. I could ask my friend for you whether the bankstown campus lockers are for the students if you like.
The story I heard regarding lockers was that people kept leaving food and stuff in them and UWS had a rat problem so they no longer let students use them.
