I'm doing FY now. There is a morning stream which has lectures start at 8 am 4 days a week. There is also an afternoon stream which has lectures starting at 12 however you also have to consider labs - the afternoon stream has these in the morning, and I think they tend to start at 8 am as well (not sure though, I am in the morning stream myself.) however, there are no lectures on Wednesdays, so you could probably organise it so you have an afternoon lab each Wednesday and only one morning lab each week. I think in semester 2 it is a bit more chill, with classes/labs starting at 9 am instead.
You have 3 labs and 1 tutorial every fortnight, and it is definitely a good idea to swing it so you only have two each week, otherwise your weeks would alternate between high stress and relaxed - which sucks if your tests fall into the high stress week. Also, I recommend enrolling quickly so you can get a good lab schedule - last week some people had their BIOSCI 107 and CHEM 110 labs on Wednesday, and then immediately had the first POPLHLTH test which is traditionally a pretty stressful test. I really did not envy them!
Oh and a warning in advance - enrol via the Cohort method in the timetable planner. I initially involved through the older, class search method and almost missed out on doing the year after being removed from my semester 2 classes because this was the wrong method. Good luck for getting in!
