The club has participated in the South Australian Amateur Football League since being formed.

[1] PHOS Camden was formed in 1994 through the amalgamation of Plympton High Old Scholars Football Club and the remnants of the Camden Football Club.

The Plympton High Old Scholars Football Club was formed in 1971 and based at Myer Oval (later to be known as N. S. Bull Memorial Oval), behind the former Plympton High School.

The club colours were decided as chocolate and blue (the State colours of the time) and the jumper design was alternate chocolate and blue stripes.

[10] This merger would last until 1993 when the club split back into Greek and Camden, with Camden forming a new merger with the Plympton High Old Scholars Football Club to form the PHOS Camden Football Club.
