Offshore & Specialist Ships Australia (OSSA) was formed in March 2017 when a small group of ex Shipping people determined to do something to preserve the history of specialist ships in Australia. Initially this involved the Offshore Oil & Gas sector but quickly expanded to cover all specialist shipping such as Antarctic, Towage, Science, Defence, and more. Headquartered in the historic premises of the Mission to Seafarers in Melbourne OSSA has grown considerably due to the energy of members and supportive Corporate members.
