In 2013, Belrose joined the Sydney Shield competition and in their inaugural year claimed the premiership.

Manly Warringah Sea Eagles legends Geoff Toovey and Jason King (rugby league) represented Belrose in their youth.

The Eagles did not make the finals of the Jim Beam Cup competition in any of the four years they participated.

At the end of the 2019 Sydney Shield season, Belrose finished last on the table and claimed the wooden spoon.
