Wireless Hill will follow a group of young scientists from different countries who are offered the adventure of a lifetime to study their chosen projects on the remote island.

The scientists have been hired by a mysterious biotech company.

The company insists on microchipping them before they go, ostensibly for safety reasons.

And then they find a body.

The series follows the characters as they begin to sense something strange going on, and try to unravel the mystery of what they are really doing on Macquarie Island.

"I thought it would be a really interesting combination of young people from around the world going onto this island and being stuck there for a couple of years," Madden said.

"They all meet in Hobart - they're from the UK, Sweden, France, a selection of countries. Then they go to the island which is completely remote. There's no communication except for this one place, which is called Wireless Hill.

"It's the only source of communication with the outside world and they have to go in there - kind of like the diary room in Big Brother - and report their findings once a day. So it's a way to get to know the characters.

"So, they can't get off, and there's no one who can help them."

She said the idea for Wireless Hill began gestating while she was filming The Kettering Incident, and noticed the research ships from countries as far afield as France and Sweden setting sail for Macquarie Island and Antartica.

"I'd long had my eye on Macquarie Island, just because it's a fascinating island - it's very unique for scientists, and I did some research on it and as usual, a few ideas melded together," she said.

"It's the only place in the world where the Earth's crust comes up through the ground. It's an amazing place."

It's still a fair way off. Madden and the writing team - she is once again pairing up with John Molloy, her partner on The Gloaming - have received funding from Screen Tasmania to begin writing the script.

"We've also got interest from a Swedish production company - it would be a natural co-production, because it lends itself to a more international cast," she said.

Vicki Madden was the creator and showrunner of two successful TV series set in Tasmania: The Kettering Incident on Foxtel and The Gloaming on Stan.

She has also been working on season two of The Gloaming, which will follow police officers Molly McGee and Alex O'Connell solving a new mystery, after the witchcraft-infused murders of season one.

Wireless Hill will be in her now-trademark Tasmanian gothic style, with supernatural and occult elements and a strong sense of the foreboding landscape.
