Australia’s Largest Choir.

One Big Voice brings thousands of students together to perform uplifting, life-affirming songs. Join Australia’s happiest youth choir event!

Our Mission

One Big Voice is Australia’s largest inclusive children’s choir, welcoming students from all schools public, private, independent and home education from Years 3 to 7.

Each year, more than 8,000 students come together at Perth’s RAC Arena for two unforgettable performances that celebrate far more than music. Children, families, teachers and communities unite to experience the joy, confidence and belonging that come from singing with one voice.

At One Big Voice, we believe every child deserves the opportunity to feel seen, heard and valued. Through powerful songs and meaningful messages, we inspire kindness, courage, resilience, integrity and connection creating lessons and memories that continue to resonate long after the final note is sung.

Together, we celebrate the life changing power of song and the extraordinary impact of young voices united with purpose.

Testimonials

Voices from the Community

“Being involved in OBV for my choir is wonderful as we come from a small country town, and it gives my students the opportunity to sing with other schools which is something that cannot happen at home. They are all so keen to sing the songs which are all positive songs and every single one of my choir students loves being involved in this event.”

“Wow! What a pleasure and honour it was to sit back and watch the future of this country come together without the prejudice, racism and problems adults bring into this world and just enjoy themselves and each other in a fun and safe environment through music. Well done One Big Voice!”

“Thank you so much for absolutely everything! You guys are amazing with all of your hard work, passion, dedication, support and encouragement! It was an absolute pleasure and honour to be a part of your concert. Thank you for everything. Now have a well-deserved break.”

“From a teacher perspective, I have found that the songs provide a solid body of work to use with the students. Some of the songs are also suitable to use in a class setting. I have found that the students appreciate the more technical songs and love the challenge. The PD’s are a delight to go to – not all PD’s are like that. To participate in singing with other music teachers and to challenge oneself with new songs is wonderful. The networking that goes on is also very useful.”

“Yes, we will be back for sure. Amazing and inspiring!”

“To all the people involved in the One Big Voice Festival, AMAZING! Thank you so much for this beautiful event! The students from St Mary MacKillop College in Busselton had a wonderful time! Many firm friendships were forged during our rehearsals and participation. We sang all the way home in the bus. We are so grateful to you!”

“The children love being part of this massed choir experience. It is such a friendly, happy, non-competitive and enjoyable atmosphere that they want to be part of it every year.”
