The Tumby Bay Museum is aiming to create more space for exhibits after the land and building is transferred to the National Trust of South Australia.
The state government announced last week the museum would be one of 19 heritage properties transferred to National Trust ownership.
Tumby Bay National Trust branch chairperson David Brand said the news meant the branch could finally move ahead with plans to expand the facilities.
“We’ve got plans that are already prepared and there’s a grant we know we can get our hands on...but we couldn’t go for that grant because we didn’t own the land or the building,” he said.
The museum building, a former building used for the old Tumby Bay School, has been on the site since the government granted use of the land to the National Trust branch in 1974.
The collection features items with links to the district and to families who have lived in the district since the late 1800s.
