You can’t miss these paste-ups walking around the city, and some are in excellent locations, for example what was once ‘Bondi Beach Club’ on the quays, which has sat empty for some time now. If the city is closing up, and being boarded up, in front of your eyes, do something with it I suppose.

Covering boarded up windows with high quality art/grafitti would be an excellent addition to the cityscape. Of course, the problem would be with dealing with the shite!
