erhm... I guess different people have very different opinion about which uni to choose. Clearly Lexi has given some very useful information on UTS nano, and in order to find out more about the SUBJECTS at other unis, you really have to go into their website and check out what subjects they actually do. It is your choice and it really depends on your interest in specific field of science. If you like chemistry for example, then you would prefer UNSW, as you do a lot of CHEM subjects in your degree.
And UAI cut offs don't indicate anything. You do not know the quota (how many people can gain a place), which ultimately determines the cut-offs.
And on equipment wise, the faculty of Science at UNSW has a lot of resources and facilities. SO I wouldn't worry about the lack of apparatus here.
Someone said they wanted to do evolutionary Biology and psychology, well, I am doing Biology at first year level now and it's called "Evolutionary and functional Biology". We just dissected a rat and a toad, so if you like to do that, you should choose Science and minor in Biology, while majoring in Nanotech.
