Honestly, Social life here isn't that great if you aren't outgoing.
Spend a lot of time at uni in your first year though and get to know people with commonalities.
Don't waste time socialising with international students - I can't stress this enough - It's nothing against them, they just prefer to stick to their own groups 90% of the time. European international students are the exemption though.
It will take about a year to develop those few close friends, my brother went through the B.Business degree and didn't really make many friends at all, maybe 1 or 2 who he works with. And I wouldn't have called them close friends. He's not outgoing though and isn't open-minded. He goes to uni and comes straight back- wheres the fun in that ?
I myself took advantage of the UTS Gym in between classes, spent time in the library with class mates after class and hung out in the Building 10 break-out room's with class mates afterwards in my first years. My degree also had a special camp for the IT faculty, I didn't attend this but most people came out of it as friends.
Also, attend O-Fest, I know this year has some hectic lineups but it's just a mad time for first years - especially if you stay there from the morning and meet randoms.
Points?
- be outgoing
- make the effort to hang around where your faculty is
- talk to people and try get to know people with commonalities
- don't take uni and life too seriously and your social life will be great
