The South East Cricket Association (formerly the City of Moorabbin Cricket Association (CMCA)) is a large amateur cricket association based in Melbourne, the capital city of the southern Australian state of Victoria. The SECA has provided a well-organised and affordable cricket competition for the local community since 1930. The majority of affiliated clubs are based in the Cities of Bayside, Glen Eira and Kingston. SECA is currently affiliated with the Victorian Metropolitan Cricket Union (formerly known as the Cricket Union of Victoria).

The SECA senior competition consists of around 120 teams organised into 9 grades. This comprises mainly teams from SECA primary-affiliate clubs, plus a small number of lower XIs from the Victorian Turf Cricket Association (VTCA). The premier grade (Longmuir Shield) is named in honour of the late Ray Longmuir, a past president of the CMCA.

The SECA junior competition consists of around 180 teams from 33 clubs in Under 18, Under 16, Under 14 and Under 12 grades, including Friday night Under 18, 16 & 14 grades. The competition comprises junior teams from SECA primary-affiliate clubs, the Victorian Sub-District Cricket Association and the Victorian Turf Cricket Association.

In addition to running club cricket, the SECA fields an U-21 team in the VMCU Neil Wright Shield, plus 5 representative teams in the VMCU Representative Carnival.  Our most recent successes include winning the U-21 Neil Wright Shield in 2011-12 and 2012-13, the U-16 Beitzel Shield in 2009-10, and a trifecta of U-14 Allen Shield, U-12 Mitchell Shield and U-12 Josh Browne Plate in 2008-09 and 2012-13.
