Mohr moved to the Gold Coast for the remainder of his career. Mohr made his debut for the Gold Coast in Round 1 1990 against Cronulla which ended in a 32-2 defeat. In 1991, the Gold Coast changed their nickname from the "Giants" to the "Seagulls" but finished last on the table claiming the wooden spoon. The Gold Coast then went on to finish last again in 1992 and 1993. Mohr retired at the end of the 1994 NSWRL season.[2]
