It was first detected on a farm in north-west Tasmania in July, also marking the first time it’s been found in Australia.
“Australia boasts a top-tier national biosecurity system, essential for protecting our economy, environment, and lifestyle,” they stated.
How did it get here?
She noted, “The exact method of its introduction to Australia remains unclear; it might have arrived through various routes.”

A Biosecurity Tasmania spokesperson said PMTV has been detected across multiple sites, including growing sites, a research site and storage facilities.
She expressed concern that if the virus has been present in Tasmania for the last two years, it may have already spread to other parts of the country.
“If it has not spread to the mainland, then obviously the industry and government want to work towards containing it.”
Learning from New Zealand
Trufitt said washing down of machinery when moving between farms, crop rotation and improving soil health were crucial in preventing the disease.
The vector: powdery scab
“If that’s the case, then [PMTV] may be further than Tasmania. We don’t know that, it’s a bit of an unknown right now.”
