SeaLink had acquired the previous ferry service founded by Peter March. Its first vessel was Philanderer 3, the first of March's vessels to carry vehicles. In later years, the company operated the Island Navigator (purchased 1990), also a car carrying ferry, as the designated freight and fuel carrier.

SeaLink has outlasted several competing companies since it began operations. Boat Torque, a Western Australian company, operated Superflyte from 1994 until 1997, whilst Kangaroo Island Ferries had a short-lived venture with SeaWay, from September 2004 until February 2005. Under different ownership, SeaWay recommenced services in August 2007, before its operations were suspended in May 2008 and an administrator appointed shortly thereafter.

SeaLink holds a virtual monopoly on oversea transport, primarily due to its long term lease of the Cape Jervis berth. Sealink's agreement with the SA Government, expiring in 2024, precludes other operators from utilising the Cape Jervis facility for one hour before, and one hour after any scheduled SeaLink service. Kangaroo Island residents have expressed displeasure with the exclusive arrangement granted to SeaLink.

SeaLink had state government subsidies with respect to its freight charges, which ended in 2003.
