There is another thread for ursies O week , which also has a bit of general info...
But hell yes u should be excited, especially about O week.
1st things 1st... if ur living on campus, u should have a absolutely kick ass, best time of ur life O week (if ur going to johns, multiply the fun level by 10). If however ur not living on campus, u should still have fun, there is just not as much stuff to do (going on what i observed last year)... i think the ANU student assosciation or whatever organised a bar crawl... but apart from that im really not sure what else went on... If ur in college, they have pretty full programs so u wont be doin much with non on-campus ppl, and u'll mainly be assosciating with ppl from ur own hall/college. So with that in mind, i will attempt remember what went on in the drunken haze of O week last year from the perspective on a johns 1st year....
Sunday: arrive, start unpacking, introduction to the college etc... go to Belconnen waterpark that night
Monday: setting up room etc, meet ppl, talks with the RA, corridor dinner that night, kick on to Moose
Tuesday: Hawaiian bar crawl to the beer garden, holy grail, moose, icbm and many other places
Wednesday: Toga night with Burgmann (got rained out), drink at the Tav (johns bar), foam party at one of the clubs (still in togas)
Thursday: Big concert thing for all of ANU with Paul Mac, movie night
Friday: Fantasy Island (oh yeh, i loved that day)
Saturday: Out the Back Day
There was many, many things happening also which i really cant remember/want to forget lol. Im sure the 07 program will change a bit from last year, and all the halls/colleges have different programs but i hope that gave u a bit of a look at what should be one of the greatest weeks of ur life!
