The Malayan Sub Aqua Club (MSAC) is one of the oldest amateur diving clubs in Malaysia having been formed in 1959 in Kuala Lumpur. It is a non-commercial, non-profit, multi racial club for diving enthusiasts who are either already qualified as snorkel or SCUBA divers, wish to take up the sport or who merely have an interest in the marine environment. MSAC is interested in conservation and the environment but it is not a pressure group. We are a sports club.

The Club has its headquarters in Kuala Lumpur where it meets regularly for training and social purposes. 

MSAC is the Malaysian representative within the World Underwater Federation (CMAS) and is a member of the CMAS Technical Committee.
