QUEENSLAND'S most-haunted site is the Brisbane Arts Theatre on Petrie Tce.

The Queensland Paranormal Society provided The Sunday Mail with its 10 most-haunted sites and the theatre – where the ghost of founder Jean Trundle is said to haunt the floorboards and backstage – was top of the list.

Paranormal Society team leader Shane Townsend said the theatre was a hot spot for activity.

"Every time that we've been here doing an investigation we've found that the footage and the different groups of people have caught different things, but when we go through and collate the information a lot of the findings are very similar," Mr Townsend said.

Brisbane Arts Theatre president Alex Lanham said he was not superstitious until he began work at the theatre but had become used to sharing an office with a ghost.

"My first experience of the theatre was in 1990, on the second-last full-dress rehearsal I came walking on stage and there was a figure up walking on the balcony and making a bit of a racket," he said. "I stopped and had a bit of a whinge to the stage manager about the sound people and the lighting people but they were all down behind the stage.

"They asked me where this person was. I pointed out the chair and they told me it was Jean's chair. And that was the first time I heard about Jean."

Jean Trundle founded the theatre with her husband, Vic Hardgraves, in 1936. Flamboyant and eccentric, Trundle died on July 23, 1965, at Ashgrove and was cremated.

"People love theatre and they love performing and they love the adulation," Lanham said.

"You have got to have an ego to get on stage and to be involved with theatre.

"My personal belief is that some people can't leave that adulation – they need to keep receiving it.

"My theory is that the reason Jean hangs around is her husband's ashes are buried in one of the garden boxes upstairs."
