Bull attended Manly Boys High together and played his junior football with the Freshwater club. He made his first grade debut as a 17-year-old in Manly's inaugural top-grade season in 1947 after having played in Manly's winning 1946 President's Cup team. The club's junior success played some part in their selection for promotion to the first grade in 1947 with the NSWRFL promising the club first grade status should they win the 3rd grade competition. Bull was a key member in the great Manly sides of the 1950s and played in all three unsuccessful Grand Final attempts during that decade - 1951, 1957 and 1959. The Gregory's reference written only a few years after his playing career had ended noted him as an expert scrummager and outstanding in tight forward play. He was a powerful, remorseless, non-stop player, great in the wet or when slushy fields covered up his lack of pace. He played 182 games for Manly up until his retirement in 1959 a record at that time, scoring 25 tries. He was captain-coach in 1953 and was made a life member of the club in 1962.
