"Geosounder" returned to Geraldton on 20 March, but delays in installing and testing the ROV prevented departure until 29 March, with the ship sailing through the path of Cyclone Pancho. "Sydney" was the first to be inspected; electrical problems with the ROV set the start of filming back to 3 April. Six ROV dives were made over a five-day period, during which the main hull and debris field were inspected, filmed, and documented. The damage found by the search team corresponded with the descriptions given by "Kormoran" survivors after the battle. After the conclusion of ROV operations near "Sydney", "Geosounder" travelled to the wreck of "Kormoran". The search was declared complete just before midnight on 7 April.
