Rodney “Murrum” Kelly of Bermagui is currently in Britain to meet with the museum as well as the University of Cambridge Museum of Archaeology and Anthropology that also holds a number of artefacts in its possession.

“I felt gutted like really disappointed,” Mr Kelly said after the museum stalled on discussions to repatriate a Gweagal clan shield and numerous fishing spears taken by Captain Cook's crew from the shores of what is now called Botany Bay in 1770.

Through his mother’s family, Mr Kelly is a direct descendant of a Gweagal warrior known as Cooman, who was shot in the leg by a crew member as they approached the shore.

Mr Kelly was joined by high profile QC Stephen Grosz at a meeting with the museum’s director, deputy director and curator of the Oceania collection.

“When Stephen introduced himself they were unsettled and they wasn't so nice when talking to him,” Mr Kelly said.

After a crowdfunding campaign allowed Mr Kelly to make his first ever flight on a plane to attend the historic meeting, he had held hopes the museum would come to an agreement on repatriation measures.

“They don't respect indigenous peoples culture it makes me angry, the place where the shield is is among many items from everywhere,” he said.

“Nobody sees the shield, and I feel like it will be a long battle, so it's disappointing and makes me more determined to see the artefacts come home forever.”

In a statement released by the museum, a spokesperson stated the “museum doesn't return objects, in general."

After a private viewing of the shield, Mr Kelly said metal rods used in the display are damaging the wooden shield.

“They are not treating it the way they should be, and they were told that,” he said.

Mr Kelly was due to meet with directors at Cambridge on Thursday to discuss the return of fishing spears, known as gararra.
