In 1976, Deans was transferred to Luton Town in a £20,000 deal. He spent a month on loan to Carlisle United in 1977 and played briefly with League of Ireland side Shelbourne (5 league games, no goals) before moving to Australia to play for Adelaide City. He is still a hero to the Adelaide fans for his goal-scoring abilities when he was the leading scorer in Australia in 1977/78. With the club he also won the Australian Cup of 1979, defeating St. George in the final 3–2. He returned to Scotland with Partick Thistle in 1980, where he retired.
