Gerrit Goedknegt was born in Vlaardingen on 17 January 1907, the son of Teunis Goedknegt and Gerritje Bal. His childhood was marked by tragedy when his father drowned at sea in 1918, leaving Gerrit fatherless at the age of eleven. The sea would nevertheless remain a defining influence throughout his life.

As a young man, Gerrit joined the Dutch merchant navy and became a first engineer with the Rotterdamsche Lloyd. During the Second World War, Dutch merchant ships and their crews became part of the Allied war effort. Subject to the wartime sailing obligation, Gerrit spent much of the war at sea under dangerous conditions. Among the vessels associated with his later merchant-service career was the Hondsrug, a small Dutch cargo ship originally built in 1937 as the Anbeja.

After returning to the Netherlands on extraordinary leave in 1946, Gerrit left the merchant navy and entered the international dredging industry. This allowed him to use his extensive maritime and engineering experience in a new field at a time when Dutch dredging expertise was increasingly sought for major projects overseas.

On 22 June 1950, Gerrit flew with KLM from Amsterdam to Melbourne as part of the first group of Dutch workers recruited for the Australian dredging project. The surviving seating plan records “Dhr. Goedknegt” in seat B4—remembered by his family as “4B”.

Gerrit initially travelled without his family. His Scottish-born wife, Margaret Doak, and their young son Teunis followed by sea, arriving in Melbourne aboard the Johan van Oldenbarnevelt on 8 October 1950. Their recorded destination was 94 Power Street in Williamstown, close to the centre of the Dutch dredging community.

Gerrit’s story connects several strands of Dutch-Australian history: the sacrifices of Dutch merchant seamen during the Second World War, the international expansion of the Dutch dredging industry, and the organised migration of skilled workers and their families to post-war Australia. From Vlaardingen and the wartime merchant fleet to Williamstown and Australian dredging, water remained the enduring thread running through his life.
