Sonny Chua (2 November 1967 – 9 September 2020) was an Australian composer, pianist, and music educator.

The eldest of four children, he also lived in Kuala Lumpur, Singapore and Malacca, before the family immigrated to Melbourne, Australia.

He attended the Victorian College of the Arts Secondary School (VCASS), studying piano under Stephen McIntyre.

He completed a Bachelor of Music degree at the Conservatorium of Music of the University of Melbourne, specialising in piano performance, with Ronald Farren-Price AO, Alexander Semetsky and Max Cooke; and also studied composition with Peter Tahourdin, Barry Cunningham and Brenton Broadstock.

[4] Chua's contributions at Melbourne High School are of broader notability in light of his development of the Massed Singing culture and his direction of the Chorale,[4] which serves as a model for use of singing as a developmental and educational tool.
