Memorial plaque, unveiled in 1948 at Weymouth Bay, for the members of Edmund Kennedys expedition who died there
It was one of the Australian places named by James Cook during his voyage in HMS Endeavour northwards along the east coast in 1770; he named it on Friday 17 August 1770.
Weymouth Bay was significant in the exploration of the Cape York Peninsula by Edmund Kennedy in 1848. During their journey north from Rockingham Bay (near the present-day town of Cardwell), Kennedy left eight members of the expedition at Weymouth Bay, intending to pick them up later on the return by sea. However Kennedy and all but one member died later during the journey; all but two of the eight members left at Weymouth Bay died before they were relieved.
