This is just something we don't see enough of in Australia.
Intelligent, subversive and anti-establishment street art that remains open-ended and unresolved once viewed. It says "think about this", rather than "do this, or you're less of a person" like advertising does. It's noise/static that gets people thinking, even if a rational conclusion isn't met.
This could also be effective/true next to "Welcome to Brisbane".
