Gethin is internationally recognised for her dynamic conducting style[1] and has engaged with symphonic ensembles across Australia, New Zealand, Asia and the United States.
[2] Her expertise as a conductor encompasses symphonic works, opera, ballet, contemporary music, film scores, to pop recordings.
[7] This endeavour led to her becoming an inaugural Fellow at the Hart Institute of Women Conductors with the Dallas Opera, where she has been mentored by Emmanuel Villaume, Nicole Paiement and Christopher Seaman.
Her father Ray Walker, an Irish-born musician and former lecturer in jazz guitar, and her mother, Teresa, a choral singer, were her first musical role models.
Gethin's musical talent was evident early on and she was the recipient of a scholarship to St Mary’s Anglican Girls’ School in Karrinyup, Western Australia.
