Ballarat Baha'i Community marked the bicentenary of the birth of prophet Bab, who paved the way for faith's founder Baha'u'llah on a mission to promote unity in humanity, regardless of religion or culture or race.

"It's important to be together and play together," Eli told The Courier. "Not to be mean to each other."

The Baha'i Community and friends joined international celebrations with the festival.

The free community event explored unity through art, games, storytelling and singing. Festival goers were also treated to a barbecue lunch.

Artist Shelby Sherritt was on hand with ceramic creations. Milk Bar Choir, including a rendition of Toy Story tune You've Got a Friend in Me.

Ballarat Baha'i Community member Della Vreeland said oneness in humanity was an important grassroots message, particularly amid such turbulent global times.

Ms Vreeland said for Ballarat, it was great to have such a good turnout from across the community to support the festival, aimed for children aged five to 10.

"It's all about bring people together from diverse backgrounds and ages with a unifying message," Ms Vreeland said.

"It's awesome to see such diversity here at the event. The fact people are coming from an array of backgrounds shows this. Everything we do is as a whole community."

Ballarat Baha'i Community's annual Light of Unity children's festival was held at Doug Dean Sports Stadium in Delacombe. The Baha'i community also runs children's classes at the hub.
