Wests formed in 1949 with the amalgamation of clubs in the district (primarily Unanderra and Mount Keira).

Cronulla Sharks legend, Tommy Bishop also guided the team to a premiership in 1978.

They did eventually break the drought in 2009 when they defeated reigning premiers, Thirroul, 14–4 under coach Paul McGregor in his first season.

In 2018 Wests found enough to hold off Thirroul 18–16 to claim their first Illawarra League crown in eight seasons.

The Devils ran in four first-half tries to lead 18–0 at the break before a second-half fightback saw the Butchers get within two with 18 minutes to play.
