Voltz holds a Bachelor of Music (Hons I) from The University of Queensland, where he studied viola performance under Patricia Pollett and then composition with Robert Davidson, Nicole Murphy and Catherine Likhuta.

He has also benefited from the mentorships of several other leading Australian composers, including Brenton Broadstock AM, Brett Dean and Melody Eötvös. Voltz also holds a Bachelor of Arts, majoring in Ancient History/History and Writing. He has penned articles for Limelight Magazine and 4MBS Classic FM 103.7, and writes regularly for The Spectator Australia, Politicom and Quadrant Magazine.
