The Frankston Susono Friendship Association Inc. (FSFA) is a local community based organisation that was established in February 1982 at the direction of the Frankston City Council. The association was formed to administer the affairs of Frankston's Sister City relationship with Susono, Japan on behalf of the people of Frankston.

The two cities have been 'sisters' since 1982 following two (2) years of discussions between Frankston City, Yazaki Australia, and the late Sir Philip Lynch (Federal MHR).
