The success of "The Display" led to Helpmann's appointment as co-director of the Australian Ballet in 1965. His biographer Christopher Sexton comments that Helpmann and van Praag "complemented each other with their different personalities and skills: she the pedagogue, teacher and administrator; he the restless 'jet-setting' star who spent six months of the year overseas and attracted international names to perform with the company". His ballets for the company during the rest of the 1960s were "Yugen" (1965); an expanded version of "Elektra" (1966) and "Sun Music" (1968).
