In 1770 Mr Kelly’s warrior ancestor Cooman was shot in the leg and wounded by Captain Cook’s marines at Botany Bay.

During a meeting with the British Museum last year he was denied the return of a shield and a number of spears taken after the Gweagal people’s encounter with Cook’s men on that fateful day.

Mr Kelly is hoping to drum up political support in the UK for the repatriation of the artefacts during his upcoming two week campaign.

“I’m going to stand out the front of the Cambridge Museum [of Archaeology and Anthropology] handing out flyers, and talking to anyone I can,” Mr Kelly said ahead of his flight to London on Friday.

“I will be trying to get supporters in the UK, so I will do the same thing at the British Museum, British Parliament and the Queen’s Palace.”

During his initial visit late last year, Mr Kelly made a shock discovery while deep beneath Berlin’s Ethnological Museum .

He discovered a second Gweagal shield and an engraved boomerang in the museum’s basement after scouring the pages of the museum’s 18th Century Australian catalogue.

Last year motions were passed in both the Australian Senate and NSW Parliament in support of Mr Kelly and the Gweagal clan’s struggle.

“It is a positive step for Mr Kelly’s campaign that the Australian Senate has expressed its support for repatriation of these important artefacts, and has requested the Australian Government to extend diplomatic assistance to Mr Kelly,” Australian Greens Senator for WA Rachel Siewert said at the time.

“It is core to Aboriginal belief that artefacts must be kept on country they came from.

“This has been a sustained campaign by Mr Kelly; I hope the British Museum does the right thing”.

Mr Kelly  said he has future trips planned to increase support for the repatriation of the artefacts.

“I will also be organising some talks for the next trip, when I will take some Elders and dancers over,” he said.

“I’m going to do all I can to bring the artefacts back home after they were taken from Botany Bay in 1770 by Cook“
