She was refloated on the tide after having becoming stranded and drifted till she was finally lost five miles (8.0 km) east of Black Head, Gerringong on 10 September 1931.

On the forecastle deck a windlass for working the winch was fitted, and an anchor of the stockless type housed in a long hawse pipe.

[1] The vessel was described by one of the crew: Government trawlers Brolga, Koraaga, and Gunundaal left for Sydney on 17 February 1915,[3] came out via the Suez Canal, and had an uneventful trip with the only bad weather being in the Australian Bight.

The Manager, David Stead was sent to Great Britain to examine steam trawling methods and acquire the necessary ships and crews.

By 1922 this network had grown to 20 outlets, 14 of which were in the Sydney area[6] By 1920 due to consistently large financial losses arising from State Trawling Industry operations, management was replaced and a major cost-cutting program was begun.

[8] On Monday 16 July 1917 the Koraaga found the Swift, an 86 ft (26 m) motor launch, which was drifting between three and four miles east of Botany Bay, as her engine had broken and it was brought into Sydney.

On 8 October 1917 the trawlers Koraagaand Gunundaal, manned by the Royal Australian Naval Brigade under Lieutenant-Commander F. J. Ranken, RNR, began to sweep a German minefield off Gabo Island.

The vessel fouled by the Gunundaal could well be the Woniora, built in April 1863, which sank on 28 October 1882,[14] which is regularly dived in 63 meters of water.

[22] The trawler Koraaga continued to work hard but returned early to Sydney late on Wednesday 2 October 1929 with a broken foremast.

As early on the Tuesday, morning, when the ship was 28 miles south of Cape Everard, the mast broke about 10 feet from the deck, under the strain of a trawl full of fish which was being hauled in.

[23] A few weeks later a German mine, apparently one of those laid in the track of shipping off Gabo Island by the raider Wolf in 1917, for which the vessel had previously been engaged in clearing was recovered by the Koraaga 14 miles east by south from Cape Everard on Thursday morning 24 October 1929.
