Gosnells Mayor Olwen Searle said the festival showcases the vibrancy in the community.
“With plenty of free or low-cost activities on offer, I encourage everyone to join in the fun, whether you feast your eyes on fantastic performances, or enjoy a feast for your stomach with our Food for Thought series,” she said.
“You could also stretch your muscles and minds with our eco adventures and skate park series, enjoy some arts and crafts, or go wild at our children’s and family activities.”
Some of the other events that will occur during this year’s festival include Little Scribblers at the Circus and Ghost Walks.
Illuminate is a free and ticketed event running from 5 to 9pm on February 18 at Gosnells Oval on Stalker Road.
