Dubbo's "predominately-vacant" Oliver House has had one owner since the mid-1960s but that may be about to change.
The Australian Workers' Union (AWU), which built the city's only high-rise office tower, has put it on the market.
Expressions of Interest to buy 32 to 40 Church Street, including five-storey Oliver House, the adjoining heritage citadel and a car park, must be lodged with Bob Berry Real Estate at Dubbo or Savills Australia by 1pm on October 25.
Licensee of Bob Berry Real Estate, Graeme Board OAM, is confident of local interest in the property.
"There will be interest from away but there will certainly be local interest," he said.
"There are a few developers in Dubbo who have been very good for the town and hopefully they can see the way forward with this."
Mr Board said in the past the now-vacant citadel had been a magnet for people interested in turning it into a hospitality venue.
"The AWU was never open to selling it separately," he said. "They're still not."
The union is selling off "a number of assets in regional centres", Mr Board says.
The Dubbo property is being marketed "as is", albeit in a prime central business district position and with B3 commercial core zoning.
Mooted uses of the building include residential accommodation.
"It could be offices, retail or you could change it to residential if council will approve it," Mr Board said.
"It will be interesting to see where the market sees it."
The first anchor tenant of Oliver House was the NSW Department of Health which took up four floors.
The first floor was occupied by the AWU and others, with a restaurant and hair salon on the ground floor.
The building is currently "predominantly vacant" with a number of telecommunication leases on the roof.
