OK, so a few things about timetables I learnt the hard way:
1) You may think you can make it to a 9am tute or lecture, but you can't. Unless you live Eastern Suburbs/Inner City, you will have to be up at 6am.
2) It is always best to minimise the amount of days you have to go. This also minimises travel costs and time, which really stack up over the course of a semester.
3) As an extension to 2), you also don't want to be there 2 days or less. You miss out on all campus life and you end up with 12 hour days. Three days a week is what you should be aiming for.
4) Try and space the days out, leaving days at home in between. This allows for precious study days at home before exams. The ideal timetable should be
Mondays, Wednesdays and Fridays.
5) Never, never, never, never ever put lectures on a day without tutorials as well. You think it'll be fine, but by week 4 you'll end up just skipping that non-compulsory day and hence miss out on 50% of your course.
6) Leave several hours of gaps and lectures between tutorials. This allows from precious cramming time if you happen to have two exams in one day, as you can skip the lectures if needs be.
7) Try to avoid putting lectures at the beginning or end of a day. You will get lazy and just end up skipping them.
8) One of the best tips I have: Pay attention to when the other lectures for that course are. If you get a shitty timetable cos one of your lectures is at an odd time, then you can always just rock up to one of the other lectures at a more convenient time. Very seldom are they actually at full capacity. This only partly works if your lecture is divided up in to two blocks, as occasionally the lecturers work at different paces and you can get confused. However, it's still better than coming all the way to uni just for a one hour lecture.
EDIT: This is mine for next semester. It's not ideal, but I made it as best as possible, given the options I had.
