I have an internship to thank for getting me my first industry job. I don't think internships here are all that exploitative. They're basically a requirement in the creative fields to get your foot in the door. That said, you do have to draw the line somewhere. Here's a great feature on the reality of creative internships: http://www.idealog.co.nz/magazine/12/creative-serfs
Word. Festivals are always a crapshoot - it's luck of the draw as to how many of the bands you'll want to see will actually be within your capability to see. I know that these days there's no point queueing for tickets when often those outlets are competing with everyone else to click 'buy' online when tickets are released. It's those compulsory Visa/booking fees that really hurt, though. You're paying nearly $200 to see the Foos/Metallica, and you wanna slap on another 3%?
