(ABC South East SA: Eugene Boisvert)The search included reviewing historical records and accounts before using a marine magnetometer to detect concentrations of iron on or beneath the seabed."We picked up this interesting anomaly, and then we dived on that target in 2023 and didn't see anything," he said."When we came back this year, we had metal detectors and we did a systematic search of that area."We saw a lot of sand again, but we were lucky enough that the windlass and a couple of other components of the wreck were exposed at the time."Wreck's role in local historyDEW's principal maritime heritage officer Mark Polzer said the shipwreck helped tell the story of Chinese migration through the South East during the Victorian gold rush."We saw a lot of Chinese immigrants coming into Robe, landing there and then walking all the way to the Goldfields to bypass a tax on immigrants coming into Victoria," he said.Mark Polzer probes the seabed during a metal detector survey for the shipwreck site of Koning Willem de Tweede.
