Career
A New South Wales representative goal-kicking back, he played club football for the South Sydney and Western Suburbs clubs. In rugby league"s first season in Australia, the 1908 NSWRFL season, Conlin captained Souths in the inaugural grand final, scoring a try to help his side to premiership victory. He was the top point-scorer for the 1909 NSWRFL season with 43 points, and that year he represented New South Wales as well.
South Sydney reached the final for the 3rd year in a row in the 1910 NSWRFL season and Conlin played in what would be a try-less draw, the premiership going to opponents Newtown by virtue of their superior ladder position.
After the 1911 NSWRFL season, Conlin moved to Western Suburbs where he played one more season.
