Hello 
In terms of my university preferences, I'm feeling quite conflicted at the moment. Although a double degree of Law (honours)/Arts at Monash seems the perfect course for me, I don't necessarily warm to the Clayton campus. The atmosphere just doesn't feel right.
Like Aaron said, it's hard to assess the atmosphere of a campus right away. When I first checked out Monash (Clayton), I felt a bit lost and didn't love it; but once I got accustomed to where things are, it really grew on me.
I'll also mention the following regarding the atmosphere of the Clayton Campus:
1) The Campus has changed, and is changing a
lot. There has been construction going on at Clayton for ages, and in my opinion, the Campus has become (and is becoming)
much better. Therefore, it might worth going to Clayton and checking out the Campus now, so you can see the new developments and see if it feels right for you now

2) As of 2018, a new group are leading the MSA, and are placing a
massive emphasis on improving campus life; i.e. enhancing the Campus atmosphere and making students actually want to come to University (rather than watching lectures online).
Furthermore, I personally believe it's incredibly important to consider the cost of completing uni courses. I know HECS can make it easy to forget about course fees, but remember that eventually, you do need to pay your HECS debt back (and obviously, a large debt isn't funny).
