1920- 1922

Cultured Pearling Made Illegal.
Captain Gregory attempted to culture pearls to the south of Broome, only to be shut down by the pearling masters. His attempts triggered the 1922 Pearling Act, which prohibited anyone in Western Australia from producing cultured pearls, in order to protect the lucrative motherof-pearl industry. Thus the Japanese continued to dominate the global cultured-pearl industry. Forty years later, when Dean Brown established the first all-Australian cultured pearling company and applied for the first cultured-pearling licence, the government officer handed Dean the pearl nuclei that had been sitting in a safe since being confiscated from Capitan Gregory and his Japanese pearl technicians.
