The skulls have been at the museum for over 125 years
Four Aboriginal skulls, which have formed part of a British museum's collection for more than 100 years, are to be returned to Australia.
The 19th century human remains were donated to Exeter's Royal Albert Memorial Museum by someone who claimed to have been given them.
They are being returned to members of the Ngarrinderi people at a ceremony on Wednesday.
A museum spokesman said the skulls had never been on public display.
The Ngarrindjeri people have been working for a number of years to have their ancestors' remains returned from museums around the world.
Tom Trevorrow, chair of the Ngarrindjeri Nation Heritage Committee, said: "The Ngarrindjeri People of South Australia are truly thankful to the Royal Albert Memorial Museum for returning our Old People's remains back to us so that they can be laid to rest once again in their own birth land.
"We have been waiting a long time for this process to take place.
"It is a contribution to the healing of wrongful and hurtful colonising practices... and a step towards reconciliation."
Kevin Mitchell, from Exeter City Council said the authority was: "delighted to be able to help the Ngarrindjeri people with their quest to have their ancestors returned."
Aborigines believe the spirits of their ancestors cannot rest in peace until their bones are buried in their native ground.
