When deciding which uni to go to, it was basically a toss up between ANU and UoM. I wasn't considering others as they were either too far away, didn't offer the course I wanted or wasn't a "top" uni. I first started considering ANU because my siblings went to it, but then I also decided I wanted to do something a bit different and try and become a bit more independent (esp. emotional, which hasn't worked very well, but oh well). ANU is also a top uni.
Ultimately, I ended up writing a list of the subjects I would do at either uni, asked the opinions of my close family on what they would prefer, asked academics about their courses/faculties and what unis had strong departments, in say English or Politics.
Eventually, I decided on ANU as I really disliked the new Melbourne model.
And I didn't think too much about moving away from friends and being all lonely or anything, as I knew eventually I would make friends, and luckily, I would have family in Canberra.
It was a really tough decision to make between the two unis, made more difficult which accommodation offers (a college didn't offer me a place till the week before orientation week started, even though they are meant to send out offers on 25th jan in 2009, and even then they didn't get me the room I asked for, or even a room that 1st years are allowed to apply for - it was a double room

). So, it was hard decision, but I had a lot of help from close family, a family friend who was doing recruiting for UoM, and my grandfather who is an academic at ANU.
