Sydney may be one of the most expensive cities in the world, but that doesn’t mean folks don’t put things on for free. If you know where to look (i.e. right here), you’ll find free art, free classes. free parties — and sometimes even free wine. So swallow your disdain for crowds and curb your complaints about people who only go to exhibition openings for the complimentary drinks and get amongst these March events, which you can attend gloriously cash-free.
