The highly-contagious disease has caused the death and slaughter of millions of pigs across Asia and Europe with confirmed cases in Australia's northern neighbour Timor-Leste this week.

Farmers fear authorities would be unable to contain African Swine Fever if it arrives in Australia as it could easily spread across the mainland via the large feral pig population in the north.

But Tasmania has another line of defence in the Bass Strait and that could "open up opportunity for pork producers locally" if the state remains disease-free, Tasmanian Farmers and Graziers Association president Marcus McShane said.

"The biggest impact is probably happening at the minute with all the pigs being slaughtered in Asia. That's creating a much higher demand for protein full stop," he said.

"So our lamb prices, mutton prices, beef prices have all risen on the back of that ... at the minute we're probably getting a lot of positives out of it."

But Mr McShane was supportive of extra government measures to keep African Swine Fever out of Australia and said biosecurity "has to be front and centre".

There are also a number of challenges that would limit Tasmania's ability to become a significant supplier of pork products to the mainland.

These include the limited availability of abattoirs, tough conditions that have pushed out operators and the small scale of the state industry, which represented 0.6 per cent of Australia's gross value of pig production in 2015-16.

And Tasmanian Island Pork Alliance chair Alan Broomby said it was still possible African Swine Fever could spread to Tasmania as the disease was "travelling pretty fast" across Asia.

"We're very concerned about it coming to Australia full stop. I know we're a long way from there (Timor-Leste) but it only takes one source for it to come into the country," he said.

Mr Broomby said Tasmania had an advantage because it did not have a wild pig population, however "we'll all be affected if the disease arrived on the mainland".

"Anyone with pigs should be very vigilant about their biosecurity," he said.

Guide Fall Farms owner Rachel Jacka said she would "seriously considering getting rid of the (around 20) pigs" she keeps if African Swine Fever arrived on the mainland.

"If it comes across our borders, my concern is for the whole of the Australian pig population," she said.

"I would assume that if all the producers follow the requirements set out in biosecurity we could be okay. But it sounds like it would be extremely virulent."

A Biosecurity Tasmania spokesperson said it was important "all Tasmanians, not just producers" were aware of methods to reduce the risk of entry of African Swine Fever, such as an awareness of quarantine requirements and what can and cannot be feed to pigs".

"ASF is spread easily by illegal contaminated food imports that might be fed to pigs by mistake. There are good awareness programs in place, such as the swill feeding prohibition/prohibited pig feed program, but they require awareness and compliance particularly by those who feed pigs," they said.

Biosecurity Tasmania has been undertaking awareness programs, sharing information and working with the Australian government in relation to African Swine Fever, including the identification of "any new measures or requirements that may be needed to further enhance our current measures".

"ASF is only a disease of pigs as far as is known. Australia's Chief Veterinary Officers are undertaking a taskforce approach with the commercial pig industry to ensure optimal planning and procedures are in place," the spokesperson said.
