One Big Voice is Australia’s largest children’s choir. Open to all schools, public or private (Years 3-7), OBV culminates annually in 2 massive concerts at RAC Arena in Perth, Western Australia. Over 7500 students and their families celebrate in joyous affirmation of the life changing power of song.

We impact young lives with the power of music, creating joy, unity, and confidence.

Singing songs about well-being and harmony.

Building confidence and emotional health.

Bringing children together in a non-competitive environment.

One Big Voice continues to be recognised for its impact on student wellbeing, connection and community – both within education and at a national level and is endorsed by the Department of Education.
