Unfortunately at the moment there is not alot of information available to confirm when the Tennis Club was actually founded. The earliest time established currently is circa 1900 by a photograph supplied by the City of Onkaparinga Library. What is known is that the club won its first A Grade premiership in 1926.
The first known location for the club was in Port Noarlunga, currently the location of the Southcoast Animal Hospital. The club was also located near the Port Noarlunga Jetty (currently a restaurant carpark) before moving to its current location in Britain Drive, next to the Port Noarlunga Football and Cricket Club.
