Fairmiles

Fairmile motor launches were small, fast, highly manoeuvrable, lightly armed craft designed in the United Kingdom. They were originally intended to be used for coastal anti-submarine and convoy protection duties but soon proved to be vessels capable of much broader operational tasking.

HMAS HDML 1324 also known as Nepean was built by A. McFarlane and Sons, Birkenhead, South Australia. After service in north Australian waters she was at Timor for the Japanese surrender in 1945. She was later reclassified as a Seaward Defence Boat.
