Edgar Newham played his first game of Rugby League at 19 years of age. By the time he was 24, Edgar Newham joined Canterbury-Bankstown Bulldogs from Cowra, New South Wales and played 9 seasons with the club between 1938-1945 and 1948.
He found immediate success when Canterbury won their first premiership, beating Eastern Suburbs Roosters 19-6 in the 1938 Final. Newham played on the wing in the Final.
Four years later in 1942, Newham crossed for 5 tries in a mid-week match against the Balmain Tigers that decided the minor-premiership. His five try record in this game was only equaled in 2002 by Nigel Vagana. Canterbury won the match 26-20 and went on to win the 1942 Premiership, beating the St. George Dragons 11-9 in the grand final.
The war years interrupted his Canterbury-Bankstown career. In 1946 he returned to Captain-Coach the Cowra league team and in 1947 he played in Queensland.
