In 1935, Lush joined the
Victorian Bar, in which he established a law practise. He would eventually serve in the
Middle East and
New Guinea, of which he rose to the rank of Captain upon his decommissioning in 1946. In February 1966, Lush was appointed a
Judge of the
Supreme Court of Victoria and would serve in that role until October 1983. After his time as a judge,
Monash University appointed him its next Chancellor in 1983. He would lead the University through difficult times due to the reduced funding by the
Commonwealth Government for tertiary education. Lush served in that capacity for nine years until his retirement in 1992. ==Honours and awards==
