Instrumental in the Bulldogs' success during the early 1990s, Pay was a skillful ball-playing forward and an especially strong defender. At the end of the 1994 NSWRL season, he went on the 1994 Kangaroo tour.
In a career-defining moment during the 1995 ARL season's semi-finals campaign, Pay broke the ribs of star Brisbane forward Glenn Lazarus in the opening moments of the match, thereby ruining the Broncos' premiership ambitions.
A year later, Pay was named as the coach of New South Wales in the inaugural under-20s State of Origin match. During 2012 Pay signed as Parammatta Eels assistant coach for the 2013 NRL season under incoming head coach Ricky Stuart.
