Our Mission: To have as many young people as possible singing positive, uplifting, life affirming songs.

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 7000 students and their families celebrate in joyous affirmation of the life changing power of song.

Now more than ever, OBV believe that we need to Keep On Singing! We are throwing open the doors and taking our mission online, providing access to songs, videos, activities, competitions, resources and much more.  Explore via  the Open to All tab. Stay connected with Facebook, Twitter and Instagram.

Students in Perth who can’t get enough of singing are invited to join our OBV Singers who meet weekly on Tuesdays and perform at the RAC Arena concert. This is open to all students aged 9-16, whether or not their school is participating in the full OBV program.

See the OBV Singers tab for details.
