Paranormal enthusiasts checked into the old Queenstown hospital on Friday night to investigate evidence from the afterlife.
Tasmania's Paranormal Experiences collected hours of footage, sound and data using specialised equipment including Electromagnetic Field detectors, Spirit Box scanners and dousing rods.
Lead investigator Stan Hurd said the Hobart-based team was still reviewing the material, however, some experiences on the top floor of the hospital were "a bit strange to me".
There was the "massive bang upstairs", the 4K camera that "suddenly turned off" and what "sounded like someone having a conversation" in the middle of the night when no one else was inside the building.
"I'm not going to say it was entirely paranormal, which is why we need to review stuff," Mr Hurd said.
Mr Hurd said he was "always very critical" during paranormal investigations and searched for reasons to explain these events.
"But a few experiences we had on the night, there was some weird stuff," he said.'
The weekend visit to the West Coast by Mr Hurd and collaborator Sam Mohne follows similar paranormal investigations of the Empire Hotel at Queenstown and Gaiety Theatre at Zeehan.
Mr Hurd said he was fascinated by the "rich history" of the West Coast and had met locals who were born at the now decommissioned hospital.
"So it was really cool to experience something that people have such a connection to," he said.
The hospital is currently being transformed into a luxury hotel by entrepreneur Josef Toth, who said it was an "absolute pleasure" to host the paranormal investigators.
"I gave them a tour and then I let them loose," he said.
"They were up all night doing their investigations with some positive results and I believe they enjoyed the hospitality."
While Mr Toth believes there are spirits lurking about, "we only have good spirits here because we're putting in a positive vibe".
"This is a hospital and that is a healing centre but at the end of the day not everyone made it," he said.
Mr Hurd said hauntings can be correlated with places of "suffering and hardship" but paranormal activity was "not necessarily a negative thing all the time".
"We heard of the grey lady that was supposed to haunt the old Queenstown hospital but she's been described also as caring," he said.
