Andrew Oakley to Present Discovery of Dutch Submarine HNLMS K XI at ADEX OZTek Australia 2025

Attendees are in for a treat at ADEX OZTek 2025, as Professional Tek Diver Andrew Oakley shares insights into the t recent discovery of the Dutch submarine HNLMS K XI off Perth Waters, at the OZTek Advanced Conference Theatre.

In January 2025, a team of WreckSploration divers—Andrew Oakley, David Jackson, and Patrick Morrison—conducting an investigation of potential wreck sites using Magnetic Survey data from Maritime Discovery Group, unexpectedly discovered the wreck of the HNLMS K XI. Clearly identifiable as a submarine, the team swiftly began surveying the site, capturing over 6,000 images to create an impressive 3D model of the wreck.

Originally launched in 1924, the HNLMS K XI played a role in World War II and was involved in the rescue of HMAS Yarra survivors in 1942. Though its service history was relatively quiet, the submarine remains an important part of Dutch-Australian naval heritage.

Andrew’s presentation at the OZTek Conference will focus on the technology behind deep-water photogrammetry and its role in shipwreck discovery.
