Federal agriculture minister David Littleproud said the government investigated a cyber attack that shut down Queensland abattoirs on Monday.
So far the attack has affected at least 6 sites operated by JBS Abattoirs in Queensland, with more across the country to be identified.
The worldwide attack forced JBS Abattoirs across Australia, the US, and other countries to shut down operations.
JBS Australia chief executive Brent Eastwood confirmed the cyber attack suspended the processing of 15,000 cattle and sheep nationally.
