In 1991 Mike McCarthy of the West Australian Maritime Museum and Kim Kirsner of the University of Western Australia coordinated a workshop to determine the most likely area for Kormoran.

The keynote speakers were oceanographers or search and rescue experts. Their analyses converged on the area supported by the Kormoran survivors, near 26° South 111° East

Oceanographic approaches cannot be used to define a precise site (e.g., Pearce, 1991); uncertainty in the direction and velocity of current and wind is too great.

Despite the fact that the oceanographic evidence provided no support for a wreck near the Abrolhos Islands, more than 200 nautical miles from the true site of the wrecks, the Parliamentary Inquiry (2001) failed to reject map dowsing, oral history or navigation-based claims for a search near the Abrolhos, and the RAN subsequently implemented extensive and expensive searches off the Abrolhos Islands

Steedman and McCormack explicitly rejected the use of reconstruction of the life-boat journey, the argument adopted by Whittaker when he turned away from map-dowsing
