Heathcliffe began his classical guitar studies under Georg Mertens at the age of 10. He then went on to study with Dr. Vladimir Gorbach at the Sydney Conservatorium of Music where he obtained his Bachelor of Music and is currently undertaking his Master of Music degree.

In 2019 Heathcliffe and baritone Brendan Zlatkis were invited to tour with the Avant Trio as part of the Sydney Conservatorium’s Great Southern Tour directed by pianist David Miller. The group gave performances in sixteen towns in Southern NSW in one week, with each concert warmly and positively received.

Later that year he was asked to perform at Sydney’s City Recital Hall as part of a lecture given by mathematician Geordie Williamson for National Science Week.

Heathcliffe has competed in Australia and internationally, and in 2019 he was a semi-finalist in the Melbourne Guitar Foundation's International Concert Artist Competition.

Also an active chamber musician, Heathcliffe has performed with some of Australia's finest talent. In 2020, he recorded a recital in colloboration with soprano Chloe Lankshear at Phoenix Central Park as part of their 'Behind Doors' series, performing works by Dowland, Hahn, and Falla.

Heathcliffe was also invited to record an album with the Sydney based collective Sideband, due for release in 2021. This album features newly composed works by Australian composer Peter McNamara.

In addition, he has premiered works by multiple Australian composers. These works include Therein Lies by Christine Pan, Concerto for Double Bass and Guitar by John Spence, and Spindian by Shaun Premnath.

Furthermore, since 2015, he has given an concert annually in his hometown of Ilford with his former teacher and cellist Georg Mertens.

He has received tuition and masterclasses from some of the most highly respected performers in the world, such as Lorenzo Micheli, Tim Kain, Z.o.o guitar duo, Dene Olding and Irena Morozova (Sydney Symphony Orchestra, Goldner String Quartet), Martha Masters, Gian Marco Ciampa, and Matthew Mccalister.

When not performing or teaching, Heath enjoys writing and his articles have been published with Classikon and Limelight.
