The Ringwood and District Cricket Association (or, better known as the RDCA) is a club cricket competition based in the outer eastern suburbs of Melbourne, Victoria. The competition consists of 31 clubs based around the Ringwood area of Melbourne and has been running seasonally since its induction in 1920/21 season.
In the 2006/07 season, the Association consisted of 32 grades ranging from Under 12's through to Veteran and Master classes. In addition, the RDCA also operate non-competitive grades in both Under 10 and Under 12 levels to assist in the development of the game.
In senior competition, Division 1 is known as the Lindsay Trollope Shield, Division 2 as the Wilkins Cup and Division 3 as the Newey Plate. These three divisions are composed predominantly of the first eleven of each club. Lower sides compete in a grading system from A Grade to M grade.
Prior to the 2010/11 season, Division 1 was known as the Chandler Shield. The name was changed to the Lindsay Trollope Shield between seasons at the RDCA AGM in August 2010 in recognition of his contributions to the RDCA for many years.
