Sydney has seen a host of live-art exhibitions over the past few months, with buildings being decorated across the city. Marrickville’s walls were transformed in a collaboration between local property owners and artists, Perfect Match, while BEAMS art festival illuminated the laneways of Chippendale with light installations, and Project 5, Volume 7 filled Darling Quarter with public live art. The pattern continues this long weekend, when 15 murals will be painted onto walls in Wollongong.

Wonderwalls is returning for its fourth year with local and international artists who will paint, spray and talk their way across Wollongong. International guests include Spain’s Felipe who uses acid colours to create mind-bending designs. Amsterdam’s Amok and New Zealand duo BMD, known for its surreal, large-scale murals, will also be in Wollongong, along with Sydney local Georgia Hill. Wollongong’s own Bafcat will also recreate one of his supernatural designs.

Free talks will be held throughout the weekend, including conversation with Brisbane filmmaker Selina Miles. Miles’ YouTube video Sofles – Limitless has had more than 10 million views and features Wonderwalls artist, Sofles. The video was filmed over 10 eight-hour days and features street artists using more than 700 cans of spray-paint to decorate an abandoned Brisbane warehouse.

All of Wonderwalls’ events are free and will be held across three days, with locations dotted across Wollongong. The opening-night party will be held at contemporary art space, Moving Mountains Gallery.

Wonderwalls will run from October 2–4 in Wollongong.
