Run by young people, with support from the Centre for Multicultural Youth, the free event features cutting-edge music from local and interstate up-and-coming artists and activities for people all ages, with the aim of celebrating diversity in the community.

There'll be a rock-climbing wall, live outside broadcasts on Voice FM, and art workshops, including street artist Bacondrum.

The musicians this year are top-class - band booker Abby Ashmore was enthusiastic explaining the lineup.

"We've got Inka Temam, who's like 19 years old, then Stella Savvy/Avek Frer's a good contrast, and we've got Alice Skye, from regional Victoria, who played with Briggs and Archie Roach on 'January 26'," she said.

"There's Krown, who's been working with some important people to create positive change and promoting social cohesion, which is what we're trying to achieve with Rock the Block, and Imbi the Girl, who's just finished Laneway and BigSound, who celebrates queer culture and diversity in that aspect."

There's also dance groups from a range of cultures, and plenty more to see and experience.

CMY's Barry Petrovski said last year's event was massive, with about 1500 people attending, and more are expected this year.

"We want to be that meeting place for different sections of the community to connect, whether it's international students, newly-arrived young people, families, and the broader community," he said.

Young people will be right at the front, encouraged to take volunteering roles as organisers, and on the day.

Magbul Choul will be one of them, and he said he's been helping out at CMY since last year.

"I've learned a lot about leadership and improvement speaking-wise, and gaining confidence," he said.

"It opens up a lot of opportunities and pathways for a lot of jobs."

The festival was a learning experience for Ms Ashmore.

"It's been exciting working with the multicultural kids because they're doing a lot of cool stuff, and it's good to be able to help provide a space for those voices to be heard," she said.

"Being around people who are excited about what they're doing makes you excited about what you're doing, it creates a positive workplace."

The festival begins at 3pm at the SMB campus on Lydiard Street South on Sunday.

This is an all-ages drug, alcohol, and smoke free event.
