The Sir Joseph bank Group comprising about 20 islands, islets and rocks is less than 25 miles from Port Lincoln and therefore an easy day sail. The trip is made more complicated than a glance at the chart might suggest because of the presence of many fish farms extending well to the east and north of Boston Bay making the trip somewhat of an ‘obstacle course’.
Although these island are low-lying and do not have the soaring cliffs and rugged coastline of the more southerly Thistle and Wedge Islands, they do have a charm and beauty of their own, and are definitely worth visiting. There are numerous reefs, isolated rocks and shallow patches within the Group, so careful navigation and attention to the tide are required.
All the islands are part of the Sir Joseph Banks Marine Park which means some activities are restricted in designated areas. Current information can be found on the National Parks and Wildlife Service website https://www.environment.sa.gov.au/marineparks/find-a-park/eyre-peninsula/sir-joseph-banks
