He became one of the most successful trainers of his time and in 1889 he and Edwin Oatley were the principals in the formation of the Warwick Farm Racing Club.

Forrester died almost destitute not long after his last winner The Watch Dog, won the Ellesmere Stakes at Randwick Racecourse in 1901.

The racecourse was formerly served by a direct rail link off the Main South line north of Warwick Farm station.

Race day special trains from North Sydney and the city were able to bring racegoers to the racecourse entrance.

The last major race at Warwick Farm was the final round of the 1973 Australian Touring Car Championship on 15 July and the circuit closed in August.
