Name

The Aboriginal name of the island is ''Temeteletta''. The island has previously been known as Lady Franklin Island, Franklin Island, Betsy Island and Willaumez Island. The first European name of the island was 'Bett's Island' after an officer who was on board an early ship exploring the region. Though an alternate explanation has been that a man called Betts was the original owner: 'The correct name is Betts's Island, the first owner having been a person of the name of Betts. Popular usage has sanctioned a different spelling.' (Cassell's Picturesque Australasia (1889): page 142)
