About Me

I am a versatile, award-winning composer, songwriter and arranger for orchestra, choir, chamber ensemble, theatre and television working from my studio in the Adelaide Hills. My choral works are performed regularly throughout the world and are celebrated for their originality and accessibility. As a passionate advocate for the environment, my works are often inspired by the natural world. My orchestral piece The Wisdom of Trees, the first of six meditations on the life of trees, was performed in 2023 by the Adelaide Symphony Orchestra. The song I Am the Earth currently has more than 5 million views on YouTube.
