definitely positive... everyone is super friendly and helpful when you first move in, it's definitely daunting to wave goodbye to your parents knowing you're surrounded by strangers in a city where you don't even know where the nearest supermarket is but everyone is in the same boat so people help each other out
I went out 4/5 nights a week for the first couple of weeks
tips:
keep your door open for the first day or two as much as possible
don't go anywhere alone, if you need to go to the supermarket/want a maccies then knock on doors and see if someone will come - opportunity to meet people
bake/bring sweets or something for your kitchen/living room and write (from ________ room ___)
don't worry about how you come across, people just want to make friends - suggest things (takeaway, breakfast out etc)
meet as many people as possible and talk to everyone, your best friends won't necessarily be the first people you meet
also: if you have any drinking games take them with you! having a game makes the first night or two a bit less awkward as you have something to do... board games are also fun/good (and can be turned into drinking games easily!)
