Tasmania Salmon Expansion Divides Dover Community Over Jobs and Environment

Tempers are running hot in Dover this weekend, as locals grapple with Tassal’s freshly lodged plans for a major new salmon farming expansion in Port Esperance. The mood at the Esperance Multi Purpose Hall Friday evening was tense, with around 120 residents filing in to view company proposals and pin down State environment officials on consultation.

The controversy matters now as the Tasmanian Liberal government pushes aggressive aquaculture expansion, promising new jobs but fuelling worry over marine health. In a town long reliant on shellfish and seasonal tourism, the prospect of even more salmon pens has exposed deep divisions. The public feedback session follows this week’s submission by Tassal to the Environmental Protection Authority proposing a 38-hectare lease just south of Rabbit Island, less than three kilometres from Dover’s main jetty.

Local Concerns and Hopes

Standing outside the Dover IGA on Kent Street Saturday morning, lifelong resident Terry Gunton gestured toward the bay. "We all want jobs here," he said, "but if they crowd the water with cages, where does my grandson fish in summer? Where do the kids learn to row?" Gunton, 71, has worked on fishing boats out of Franklin and Port Huon. His worry is echoed by local oyster grower Rebecca Wu, who operates just east of Southport. "I'm worried about the nutrients and how it’s going to affect the oyster beds, if we get another algal bloom like last year, that’s my business done." Tasmanian Seafood Industry Council reps say they’ve logged 19 official complaints about aquaculture impacts in Esperance waterways since 2023.

But some see hope. Maria Lopez, who recently moved from Hobart and now manages a guesthouse at the Dover Rivulet end, argued, "It’s hard to complain about local investment. The school’s enrolments are barely 85 kids these days. Younger workers might stay if the work is here." Tassal says their stage one could mean 22 new jobs, mostly filled locally, and that it will invest heavily in odour and noise controls at their Esperance Road shore base.

By the Numbers

Tassal’s application, reviewed by The Daily Tasmania, details an expected yearly output of 3,000 tonnes of salmon once fully operational. According to 2025 figures from Tasmanian government reports, aquaculture now accounts for $1.2 billion of the state’s seafood revenue, but local tourism still brings in $567 million for the Huon and Far South annually. Environmental groups cite water quality monitoring data from the last EPA report showing dissolved oxygen drops of up to 14% near existing salmon leases in the Huon estuary. Opponents of the current expansion argue that such statistics should trigger further study before new cages are approved.

The EPA tells residents they have until 22 July to make formal submissions about the expansion. Information packs, environmental studies, and comment forms are available at the Dover Library and on the EPA’s proposal portal. For queries, locals can phone the Community Information Line run by the Department of Natural Resources and Environment Tasmania. The government says all feedback will be reviewed before final decisions are published this spring. Meanwhile, Dover prepares for more robust debate as jobs, the bay, and the community’s future hang in the balance.
