The ship was ordered in 1970 to replace the light survey vessel HMAS Paluma. Flinders was 161 feet (49 m) in length overall, with a beam of 33 feet (10 m), a draught of 12 feet (3.7 m), and a full load displacement of 740 tons. Propulsion was provided by two Paxman Ventura diesel motors connected to twin screws, providing a top speed of 13.5 knots (25.0 km/h; 15.5 mph) and a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 9 knots (17 km/h; 10 mph). The hull was all-welded, and designed to Australian Shipping Board standards for coastal operations. Increased seakeeping ability was imparted through a bulbous bow, high forecastle, and a stabilising system. Most operations were intended to be in the waters of Australia and Papua New Guinea, although Flinders was also capable of limited oceanographic work. The ship's company consisted of 38 personnel, and Flinders carried light-calibre weapons for self-defence.
Flinders was laid down by HMA Naval Dockyard at Williamstown, Victoria on 11 June 1971. She was launched on 29 July 1972 and commissioned into the RAN on 27 April 1973. On commissioning, the ship was based in Cairns.
Following the destruction of Darwin by Cyclone Tracy during the night of 24-25 December 1974, Flinders was deployed as part of the relief effort; Operation Navy Help Darwin. She sailed from Cairns on 26 December, and as the first ship to arrive, Flinders was tasked with surveying the harbour to work out the position of wrecks and the safest areas for the other RAN ships to anchor.
Flinders was decommissioned in 1998. In October 1999, the ship was sold at auction for A$518,460 to a New Zealand consortium. She was remodelled into a private yacht, and now operates at MY Plan B, registered in the Cayman Islands.
