In 1971, Forrester made the semi-finals of the Edinburgh Knockout competition at Murrayfield, where they were defeated by The Bruce Hay-led Liberton.

The next few years saw Forrester FP Rugby Club in The Dorlin Hotel, St. John's Road, Edinburgh (no longer operating).

Forrester players who went on to achieve international honours include Norrie Rowan and Robert Cunningham (Scottish rugby) and Iain McLeod (Queensland Triathlon Champion 2001).

It was perhaps fitting that in the last year of this competition, the Castlemaine XXXX cup was won by Forrester in the gala event.

St Augustine's and Forrester High moved to a shared campus in January 2010, with the new school building situated on the former football pitches and site of the old clubhouse.
