TasFarmers, Media Release, 13 August 2025

Tasmania’s peak body for farmers says fears of a new biosecurity incursion have been realised after the Tasmanian Government announced the detection of the potato mop-top virus in the state’s North West.

The mop-top virus is a plant disease that affects the leaves, shoots, and tubers of potato plants and poses a significant threat to Tasmania’s potato crop. The virus can significantly reduce crop quality and lower returns for growers.

TasFarmers Chief Executive Officer Nathan Calman said there had been concerns in recent weeks that the virus may have been detected, and testing had now confirmed its presence for the first time not only in Tasmania but in Australia.

“The failure to protect our border from an incursion is deeply disappointing. We now need to make sure the industry is supported,” Mr Calman said.

“This new case represents a massive failure in the state and the country’s biosecurity protocols, allowing a virus to enter Tasmania and place the entire production system at risk.

“Tasmanian potato crops are a significant part of the state’s horticulture industry, and today’s announcement will cause considerable fear and concern for growers as they decide which crops to plant for the upcoming season,” said Mr Calman.

TasFarmers believes the incursion also highlighted the need to ensure Australia’s biosecurity border controls are fully funded to protect primary producers from international threats.

“We have long held the view that the costs associated with protecting our borders should be passed on to importers wishing to bring potential risks into the country and not borne by local producers.

“There will now be questions about how the virus can be contained or eliminated from the state.

“We’ve been active on behalf of growers and producers, telling the Government that producers must be part of the solution and pathway forward. If the industry wants to pursue eradication, it must be supported by the Government.

“That includes rapid mapping and tracing, movement and hygiene protocols where directed by authorities, timely updates to industry, and financial support for any eradication or containment measures,” said Mr Calman.
