You probably won't be able to do that, because the academic year starts in feburary, and there's no mid year start. The second semester subjects require successful completion of the first semester subjects as pre-reqs. Talk to murdoch, but I think you'll have to defer the whole year.
(And you're actually c/o 2014... 2010, 2011,2012,2013,2014 🙂)
Oh, and perth is awesome. Great sunny weather in summer, beautiful rain in relatively mild winter, AWESOME beaches, cute pubs and bars, great resturants, so laid back, awesome public transport, farm on campus, friendly professors, AWESOME students... *sigh*. the only thing we dont have a lot of in perth is kangaroos. Sorry!
