Fitzroy is a bit of a graff paradise. No actual designated legal wall there but heaps of open minded locals that in most cases are more then happy to let you paint their house if you ask them. Hooked up dozens of walls there within a few weeks. Might as well check for old, faded murals and ask if you can overpaint them.
*don't paint over old faded Murals- they would have been left for good reason (EG. done by Keith Harring)
there are heaps of walls that nobody cares if you paint, but there are heaps of walls that people do care. you just have to be a bit careful and be aware of who you're painting over, and who is looking over you while you do.
Is this wall still safe to paint?
