SeaCare was established in 1998 as a non-profit organisation supported by the National Heritage Trust of Australia Fisheries Action Program.

SeaCare was established with an initial focus on the ecologically keystone species giant kelp (Macrocystis pyrifera), and its interaction with the long-spined sea urchin (Centrostephanus rodgersii), short spin sea urchin (Heliocidaris erthrogramma) and the invasive Japanese seaweed (Undaria pinnatifida).  For more information on past projects completed by SeaCare, see Completed Projects.
