I visited Toowoomba recently and checked out some of the walls from the First Coat Art & Music festival. The artwork was super impressive! There's a map you can use in the first coat app if you want to walk around and hunt out all the work from 2016. I did a bit of that and a bit of freelance strolling to check it out. I didn't catch all the work this time but took some pics (photography is not my forte!) below were some of my favourites and I believe a mix of 2015 & 2016 festivals.
