Civilian is a street artist operating out of Melbourne, Australia, who has been profiled as a 'leading player' of "the city's vibrant stencil art scene". Civilian started painting stencils around the end of 2001. He has had several art works exhibited in gallery shows, but says he’s not entirely comfortable in those settings; preferring to do work in “Empty Shows” - illegal exhibitions held in derelict buildings.
