Mossop Construction Advances Mount Gambier Flour Mill Demolition for $118 Million Project
Mossop Construction advanced the mount gambier flour mill demolition on May 18, 2026, removing the 140-year-old Roller Flour Mill to make way for a hotel development. Heavy machinery razed the mill's distinctive pink dolomite stone facade after planning assessors approved the work.
The developer chose the $118 million accommodation, retail and commercial project over preservation. The site is set to host a multi-storey hotel complex in Mount Gambier's South East region.
Mossop Construction and the facade
Mossop Construction estimated $2.2 million to preserve and repair the heritage wall, then moved ahead with demolition instead. The mill dated to the 19th century and had been described as part of Mount Gambier's industrial heritage.
Local residents had launched an 11th-hour petition to save the facade, and community groups had opposed the demolition for months before the work went ahead. The petition did not stop the approval that allowed the heavy machinery to bring down the frontage.
Mount Gambier's South East site
The demolition clears the way for a multi-storey hotel complex tied to a project expected to generate jobs and boost tourism in Mount Gambier's South East region. For residents who tried to save the facade, the immediate change is permanent: the mill's frontage is gone, and the redevelopment now moves into the build phase.
The practical question now shifts to the new complex itself. The site has been committed to accommodation, retail and commercial uses, and the demolition means the project can proceed without the heritage wall that opponents wanted preserved.
