HMAS Black Snake was a Snake-class junk built for the Royal Australian Navy during the Second World War.

She was used by the Services Reconnaissance Department (SRD) and was paid off on 3 November 1945, before being handed over to the British Civil Administration in Borneo.

[1] On 26 April 1945 Black Snake, commanded by Sub-Lieutenant John Key, deployed a party of nine SRD operatives, called Giraffe 3, in the Celebes area.

Using Hoehn military folboats (collapsible kayak) a party of four, including Key, landed at Pasirpoeth to repair native boats.

[2] On 16 May 1945, a party of SRD operatives, codenamed Swift, went to Loloda Island in the Celebes via Blacksnake and used a folboat to go ashore and gather general intelligence.
