There are a number of clubs in Launceston but what happens is that everyone ends up at only ONE club, and the others are empty. A few years ago the Saloon bar was the popular night spot.
Also a word of warning - be careful in the streets, even if you're with friends. There are some locals who try to pick fights - the best thing to do is to keep walking and don't say anything if you are being provoked. Launceston can be a bit rougher than your average Australian city.
