The club, formerly known as St Patrick's Old Boys, currently field six teams in the second division of the NSW Suburban competition, known as "Subbies".

The club was formed by ex-students of St Patrick's College, Strathfield but now has members from various backgrounds including a number of international players.

Because Knox Rugby Club also played in black, St Pats made a jersey change to include gold hoops.

The club's training location was moved to Ashfield Centenary Sports Ground in 1974 and the Illinois Hotel was the de facto clubhouse.
