The state government faces scrutiny over florfenicol permits as mass fish deaths and lobster bans raise questions about industry priorities.
Tasmania's farmed salmon industry seeks emergency use of antibiotics in public waterways amid mass fish deaths and rock lobster harvesting bans, raising questions about the state's clean and green brand and whether one $1 billion sector is being prioritized over other industries and the public.

Tasmania markets itself as clean and green with a philosophy of better, not more. The salmon industry seeks emergency use of florfenicol antibiotics in public waterways after mass mortalities in the 2024-25 summer, while RTI disclosures revealed 1,907 tonnes of farmed salmon died in Macquarie Harbour between October 2024 and December 2025.
For years, Tasmania has marketed itself as "clean and green" โ a state focused on purity and sustainability.
It's a state that embraces the philosophy of "better, not more".
These are not my thoughts; they're all black-and-white statements taken straight from the Tasmanian government's own website.
But are they true?
If they are, how could a government allow the state's reputation to be put at risk by one major producer at the expense of other industries and businesses, and indeed the public?
For another summer, Salmon Tasmania, the peak body representing the major farmed salmon producers in the state, is seeking to use large quantities of antibiotics to protect against bacterial outbreaks in its salmon.
These salmon aren't housed in carefully contained on-land enclosures.
They're held in dozens of large pens within public waterways that are also used by commercial and recreational fishers.
These waterways are used by humans, too โ people swim and sail in these waters.
The state's health department is at pains to point out that there are "no reports of adverse human health effects" from eating seafood that has florfenicol residue.
And there is "no evidence of harm to human health" from exposure to the antibiotic while undertaking recreational swimming.
The salmon industry itself would also be quick to point out that the reason it wants to use antibiotics is to avoid the mass fish deaths of the 2024-25 summer when thousands of tonnes of dead fish and fatty globules washed up.
Just this week we've learnt, thanks to right to information (RTI) disclosures, that 1,907 tonnes of farmed salmon died in Macquarie Harbour between October 2024 and December 2025.
The information has come to light nearly a year after it happened, only because a RTI request lodged nearly 12 months ago was released this week.
We do not know what killed the salmon; the information does not disclose that.
Would everyday Australians understand that as "clean and sustainable"?
It's certainly not being transparent in a timely way.
Coincidentally, that information has come out as the environment department places a ban on the commercial harvesting of rock lobster and the setting of rock lobster pots within parts of the Southern Channel.
This advisory is "part of the arrangements to mitigate trade risks associated with aquaculture therapeutant use" in waterways around southern Tasmania.
Salmon Tasmania is seeking an emergency permit to treat farmed fish with florfenicol to prevent a disease outbreak that caused mass mortalities last year.
And it is pre-emptively offering to compensate other sectors that might be harmed as a consequence.
If the antibiotics are detected in other species like rock lobster and urchins, which are exported to other countries, those nations might ban the product if trace elements of the drug are found.
As one lobster fisherman, Bryce Way, told 936 ABC Hobart this week: "If you're accepting money, you're selling your soul, that's all you're doing."
In short, one commercial sector is being punished to protect another.
The perception is that the state government has made a decision that the $1 billion farmed salmon sector is more valuable than other jobs and businesses in the aquaculture sector.
Is that fair? Premier Jeremy Rockliff was asked just that on Friday.
"It's important that all sea industries coexist, and coexist amongst the best-balanced approach, which we're trying to achieve here," he said.
Early this month, Tasmanian Rock Lobster Council president Danny Fox told the ABC his people are happy for the salmon industry to be there.
Cray fisherman Kodey Rolston said many in his industry were asking: "Why is one business worth it more than others?"
"Just because it's larger? Maybe they pay more tax, maybe they pay more donations?" he said.
"I am there for salmon farming; I do like it, it's great for industry, and it keeps jobs.
AI outlook โ possibilities, not facts
The Tasmanian environment department will decide on the emergency permit for florfenicol use in salmon farming.

Other countries may ban Tasmanian rock lobster and urchin exports if antibiotic residues are detected.

Weipa in Far North Queensland has recorded 39 consecutive days above 36ยฐC during a prolonged heatwave, with hottest November day at 39.9ยฐC and 17 consecutive days above 37ยฐC. Indigenous communities face critically low water levels and rolling outages, while most social housing lacks air conditioning. Relief may not arrive until after Christmas.
The University of New South Wales eastern waterbird survey, now in its 44th year, has documented a 60 to 70 per cent decline in bird populations over decades, largely due to water diversion in the Murray-Darling. With H5 bird flu now detected in Australia's wild bird population, researchers warn its spread to inland water birds is inevitable as inland waters dry out and populations concentrate.
Provectus Algae has developed a bioidentical cattle feed supplement to reduce methane emissions from Australia's 30 million cattle, backed by a $3.8 million Queensland government grant. The product, derived from CSIRO research on Asparagopsis seaweed but reformulated using other algae after safety concerns, targets around 65 per cent emissions reduction and costs about 8 cents per animal per day.
Black Thursday, February 6, 1851, burned five million hectares across Victoria's Port Phillip colony, killing 12 people and over one million livestock. The fire shaped Victoria's birth, prompted its first bushfire legislation, devastated Indigenous populations, and continues to inform climate debate and historical firefighting research today.
Protesters gathered in Adelaide's parklands as workers felled the first trees for the $96 million MotoGP track project, which will remove nearly 400 trees including 42 significant trees between Wakefield Road and Rundle Road.
Red witchweed, a parasitic weed found on six sugarcane farms near Mackay in 2013, is being eradicated using false host plants like soya beans that trigger seed germination without providing a host, causing seedlings to die. The affected area has shrunk from 110 hectares to 4.3 hectares, and eradication could be achieved within three years under an approved proof-of-freedom plan.
