A story about a ghost on the backbenches of the House of Representatives is spooking visitors to Old Parliament House.
Staff at the Museum of Australian Democracy (MoAD) are enjoying a huge public response to a new night-time tour of the 90-year-old building.
"We've come across some very interesting stories of death and near-death experiences in the building for our research for the tour," Brian Leadbeatter said.
Mr Leadbeatter is the museum's visitor experience coordinator.
"There are stories to be told that allow people to see our museum in a different light.
"There have been deaths recorded in both chambers — in both the House of Representatives and the Senate as well as in King's Hall.
"And we're not talking about political careers, we're talking about actual deceased people."
Appetite for more
The museum's initial ghost tour ran as part of this year's Canberra Writers Festival and sold out so quickly that organisers decided there was an appetite for more.
"Some of our security guards have amazing stories about close encounters," Mr Leadbeatter said.
"It was one of our cleaners who was working in the House of Representatives quite regularly who claimed that there was a ghost at one of the backbenches who would regularly call her name.
"We're trying to figure out who this character was."
The tours run after dark and see visitors take a torchlit guided journey around the building.
"There's quite a lot of mysteries about the place," Mr Leadbeatter said.
"There are prime ministers who died in office — Joe Lyons, John Curtin and Harold Holt.
"Even prior to the opening of Old Parliament House, Alfred Deakin was a real spiritualist and participated in seances."
One of Canberra's greatest haunts
Crypto-naturalist, formerly known as Tim the Yowie Man, has been running ghost tours across Canberra for more than a decade and considers MoAD one of the city's greatest haunts.
The National Film and Sound Archive, Blundell's Cottage, the Australian War Memorial and the National Library are all included in his list of haunted sites.
"We need more mysteries," he said.
"It would be sad if there was an explanation for absolutely everything — where's the fun in that?"
MoAD will be running After Dark: Ghost Hunters tours on Thursday nights from September 7.
