The vessel came into the ownership of Cam & Sons a major player in the then-new growing industry in July 1929.

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.
No one was injured.

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.

After the trawl had been dragging for some time on the ocean bottom in 65 fathoms, it was raised and the crew stood by to receive the catch.
Those with experience of mine sweeping during the war were startled when the mine tumbled out on deck.
It stood about four feet high with a diameter of two feet and weighed about five cwt.
Long immersion and rolling about on the ocean floor had made the mine harmless.
The cap and firing mechanism were gone, and there was no cable.
A quantity of explosive still remained.
This was taken out and the mine brought back to Sydney where the trawler berthed yesterday morning.
Any marks of identification are hidden by a heavy marine growth.
Captain J. Farquhar, master of the Koraaga, who gained a knowledge of mines while fishing In the North Sea, said last night that he believed the mine had been cut adrift from a minefield during sweeping, and after going to the bottom was carried south by the current.
It was possible, he said, that the Koraaga was responsible for rendering the mine harmless, since she swept the Gabo field with the Brolga and Gunundaal.
The Gabo minefield was first discovered by one of the State trawlers, and that before the danger area was properly swept the Cumberland was blown up. "
The laying of the mines by the Wolf was very cleverly done," he said. "
They were put down at night in an area that was in full view of the Gabo lighthouse during daylight."
The mine will be retained by Mr. Cam among the many curiosities that have been brought back to Sydney by his trawlers.

This mine made the total recovered number of mines in Australian waters as 27 and confirmed the statement made by the Germans after the war that the raider Wolf had put down two minefields, each of 15 mines, along the Australian coast.
The site of the second minefield indicated by the Germans was off Cape Everard.
This area was swept on two occasions without apparent result.
