Port Lincoln is situated on one of the world's largest protected natural harbors, encompassing Boston Bay, which covers an area more than three times the size of Sydney Harbor. It was discovered by Matthew Flinders under his commission by the British Admiralty to chart Australia's unexplored coastline in the ship Investigator. Dropping anchor in Boston Bay in February 1802, Flinders named the spot Port Lincoln after his native Lincolnshire in England. Initially considered as the alternative site for the state capital of South Australia, Port Lincoln was rejected in favor of Adelaide because Lincoln lacked an adequate fresh water supply. [...] Now the home of Australia's largest commercial fishing fleet, Port Lincoln has a thriving tuna-farming industry, but also aquaculture farms for kingfish, abalone, mussels, oysters, and experimentally, sea horses and lobsters.Reference
