I worked as a freelance journalist here several years ago, two years after graduating and with just two years solid experience working for a news agency. It was tough then and it is certainly tougher now. Six or seven years ago, a lot of young freelance writers came over here because the low cost of living meant that they could work for peanuts/free in order to build up their portfolios, maybe substituting the occasional journalism gig by teaching English. I rarely came across anyone that had been lucky enough to get a half decent gig (most of them worked for the Argentine Independent and another expat magazine around at the time, wrote occasional pieces for online media,etc). I don't know how anyone could get by doing that now. The major news outlets already have stringers/contacts here with 20+ years experience so its difficult to find a niche (at least one that pays the bills). I mostly wrote for foreign lifestyle magazines (low profile ones). I got a couple of articles placed with national newspapers, a couple placed with decent (but low paying) magazines and a gig with the Lonely Planet. I substituted my income editing and translating (which I hated!) and still lived hand to mouth (and this is when BA was cheap).
If you're fresh out of university, I think your best bet is to get the best internship you can find, work a few years and then when you've built up some decent contacts, think about going freelance.
