Winemakers with land in eye line of the site of a proposed development have warned they will relocate if it is built.
Peter and Loraine Kossmann run a 100-acre property which includes a vineyard and cattle at Rowella, about 1.2km across the Tamar River from the Long Reach site where Firmus plans to build its 288-megawatt artificial intelligence (AI) data centre.
From their house, the Kossmanns have a clear line of vision to the site.
Since moving to the area for its natural beauty, they have adjusted to having a salmon farm and woodchip pile as distant neighbours. However, they feel that the data centre is different.
"We come here after we've worked all our life to have some peace and quiet, a nice river view, and it all gets changed," Mrs Kossmann said.
Among the Kossmanns' concerns is a lack of prior consultation, the risk of particulates from 276 back-up diesel generators landing on their vineyard, and rumours that property values have fallen in the area.
As much as they love their home, Mr Kossmann said it would be "time to move" if the data centre went ahead across the river.
"(It would be) time to position yourself elsewhere. I've spent a lot of time on this island, and that's not what I want to look at," he said.
Nearby, their neighbour Anne-Marie Bastian and others including Nicholla Thompson and Heather Konijn are appealing the George Town Council's approval of the AI factory through the Tasmanian Civil and Administrative Tribunal (TASCAT).
The group, the Environmental Awareness Association Inc (EAA), is appealing the approval on 12 grounds, including that the project was misclassified by the George Town Council as the planning authority as a utility, and that the council erred by approving the application based on notification material that did not disclose the risk posed by electromagnetic radiation.
Meanwhile, Firmus has appealed conditions restricting the use of the diesel generators at the site.
George Town Council general manager Shane Power said that TASCAT was the appropriate place for concerns related to planning matters to be heard.
The ultimate aim of the group's appeal is to have the project assessed properly so it takes into account their environmental concerns.
The EAA raised concerns about bushfire risk where the diesel and lithium batteries will be located.
Ms Thompson said she and her daughter were about to start a tourism venture, but those plans were put on hold.
"This is my community, and I'm passionate about that," Ms Thompson said.
In its submission to the council, Firmus said its proposal did not involve bulk fuel storage within a single facility, but would instead be distributed within individual enclosed and double-bunded generator tanks.
Mrs Bastian said the group could only appeal what fell under the 1993 Planning Act.
"(That) isn't a data centre. It doesn't fit in there to begin with, how are you meant to appeal it to fit it into there?" she said.
