More Wollongong business owners are volunteering their walls for use by street artists after a recent festival brought masters of the craft to the city.
Noted street and graffiti artists from interstate and abroad painted nine sites in Wollongong last weekend at the inaugural Wonderwalls festival.
Works included a portrait by Melbourne street artist Rone, two storeys high on the side of Keira Street's Dion Building.
Event organiser Simon Grant, of Verb Syndicate, said owners of four or five other businesses had volunteered walls for use in future festivals.
Mr Grant hopes to build Wonderwalls into an international-standard event.
"There's some really massive projects happening around the world with this sort of stuff. We did a 15 to 20-metre wall - in some of these European countries they're doing 15-storey buildings," he said.
"We always want to be pushing the boundaries."
Wonderwalls included a gallery exhibition and talks by artists including Meggs, Yok, Numskull, Roach and Phibs - believed to be speaking publicly about his work for the first time.
The talks drew audiences of up to 70 people, with some lingering to collect the autographs of artists who remain little known in the mainstream but lauded by street art enthusiasts.
