Moyne Health Services has temporarily closed its Koroit campus in Mill Street following an engineer's report.

This report said part of the building's roof structure was at risk of failure and had reached the end of its service life.

Moyne Health Services board chair Karen Foster said the board would meet later this month to assess options for the building.

Ms Foster said the board had acted quickly on the advice, with access to the grounds surrounding the building limited to ensure a safe exclusion zone in the event of a roof collapse.

All services offered at the site have been re-located for now to the Port Fairy campus.

"We are actively exploring alternative sites in Koroit and hope to be able to make announcements very soon," Ms Foster said.

"Our Board would like to assure the people of Koroit that we are not only committed to maintaining current services in the town, but we are also exploring how we can expand our offerings to meet expected future demand."

Services offered by Moyne Health Services at the Koroit campus include social support groups, physiotherapy, podiatry, district nursing, speech therapy, occupational therapy, home care packages and short term restorative care programs.

Ms Foster said the importance of health services to the community could not be underestimated, but the safety of all was the main criteria in all decisions made.

"We're very aware that this site has special significance to the people of Koroit," Ms Foster said.

"However, the health and safety of our staff and the people who access services at Koroit is our highest priority just now."

The Koroit hospital opened in 1955, before it was converted into a nursing home in the mid-1990s.

In 2011, the nursing home was closed. But less than a year later, Moyne Health Services took over management of the building.
