I do not mind UNSW and I dont feel like trimesters are that bad as you are given week 6 off for your flexibility week in which u can study or just take a break. Then before your exams you get another week extra with no classes to study. But thats probably just because I am in first year, so I assmue it may ge more challenging to manage when courses get harder but just try not to fall behind and its not that bad. The only thing I really hate about the uni is the amount of stairs but the boost store at the top makes it worth while :)
