As a rural student in your position last year your best bet is to take a trip to Melbourne and check them all out. I kinda wish I had done so myself 12 months ago.
Get the vibe of each place and go with your gut instincts. Pick a college that suits your own interests (and budget!).
I haven't experienced much of the other colleges so I'll give you a summary of Newman
Pros
+ Newman's fees are one of the cheapest (+ the college it's self is extremely generous when it comes to bursaries/scholarships for those in need. just ask!)
+ Right near lygon st and tram, the gate is legit right next to uni
+ Highest percentage of students with rural backgrounds such as yourself
+ The rooms here although basic, are clean and well maintained (everyone gets a large wardrobe & 70% of people get a sink)
+ The architectures pretty cool if you're into that hogwarts kinda vibe - Newman, Ormond, Queens and Trinity are all pretty old
+ Foods pretty good - vegie options are amazing - meals range from a good parma to a 3 course meal with creme brulee for desert
+ Pretty sick library right on college which is very handy - TV room but I dont really rate it lol
+ A community of lovely supporting people
Cons
- It's meant to be the "strictest" college...
aka if you act like a tool they'll suspend ya - so its not as rowdy as other colleges
therefore its pretty quiet when you need to study/sleep (another pro)
- oweek isn't that crazy but they do this to protect the first years.. (no hazing which is nice i guess)
(((that being said parties still happen and there's still lots of *unofficial* college mischief that you can choose to participate in if you want)))
- formalities - three formal black tie dinners a week can get tiring, a few compulsory dinners/events
- first year you might be put in a small room - its all randomly selected (you might also be put in a huge room though)
I'm pretty biased as this is the only college I've experienced but I recon its pretty good here. You can't really go wrong selecting a college its such a great option for your first year. Moving to the city/uni is pretty overwhelming and college is a great environment to transition
Good luck with exams! Exciting times!
