The artwork honours four celebrated women of the Gadigal people, Boorong, Patygerang, Daringa, and Barangaroo, who were all very skilled fisherwomen with their own unique individual stories and contributions.
“The harbour has always been integral to the everyday lives of the Gadigal people of the Eora Nation and it’s important we continue to share their stories. It is important will listen,” Sampson said.
