Warwick took up dance relatively late, training as a young man at Southern Ballet and dancing mainly character roles such as the Charlatan in Petrushka.
In 1983, he studied at the Victorian College of the Arts School of Dance, but after six months was asked to join DanceWorks Melbourne, performing new postmodern works throughout Australia. He remained with them until 1986 when he gave up dance to follow another career.
In 2015, he returned to the stage, singing and dancing in the Showbiz Christchurch productions of The Phantom of the Opera and Monty Python’s Spamalot; and Madame Butterfly for NZ Opera. His other recent performance credits include: Hairspray and Evita (Showbiz Christchurch); La traviata (NZ Opera); Max Detweiler in The Sound of Music (North Canterbury Musical Society); and Carmen (NZ Opera).
