For personal reasons, Smyth chose not to play in the NBL until 1982 and even then, while still living in Adelaide, he signed to play with the St Kilda Saints, commuting between his home in Adelaide and Melbourne where the Saints were based. He only played for St Kilda for the 1982 NBL season, winning the NBL's Defensive Player of the Year award and selection in the NBL's First Team in the process before signing with the Canberra Cannons from 1983. At this time he also moved from Adelaide to Canberra for what would prove to be 10 seasons in Australia's capital city. During that time he enhanced his reputation as one of the best ever Australian basketball players and helped transform the Cannons into a championship winning team.
