As with tennis, there is no precise record of when croquet began at Rose Bay. The first mention is of a meeting in 1905 to elect a captain and establish a committee of three.

At least two croquet lawns were in play in 1908. In ensuing years, players had to witness a reduction of their facilities as their lawns competed with tennis, and later, bowls. Croquet continued to struggle and by 1935 the remaining lawn was taken over by bowls. It was to be another thirty-two years before the game revived. In 1967, the General Committee announced that a croquet lawn would be formed on two tennis courts on a trial basis. Mrs C. R. Traill and Major W. R. H. Tingey were the key inspirations during this time. The Major won a World Championship and was the world number two player for about twenty years. Since then, Royal Sydney has been the venue for part of the interstate and part of the Australian Championships in 1991.

Presently, the Club has two croquet lawns with Riley Super Sports Couch as their surface.
