At the age of twenty seven Keith took his first modern dance classes with Gertrude Bodenwieser in Sydney. He went on to dance with the Bodenwieser Ballet and had a number of works created on him by Bodenwieser including the male role in Central Australian Suite and a solo called The Heretic. After Bodenwieser’s death in 1959, Keith, along with Margaret Chapple, took over the running of the Bodenwieser Studio in Pitt Street, Sydney. Keith taught modern, primitive, jazz and ballroom dance classes, and also choreographed for, and danced in, many Ballet Australia productions.
In 1968 Keith founded the Australasian Teachers Contemporary Dance Association (CDA), and the Society of Dance Artists (SODA). Keith established and was for many years, head of the movement studies course at NIDA. As well as receiving two Australian Dance Awards, Keith was awarded the Queen Elizabeth Silver Jubilee Medal for services to dance and theatre in 1977 and an OAM in 1988.
