Biosecurity officials are on full alert at Australia's borders as the pig-killing African swine fever sweeps through Asia.
South Korea, Australia's third-largest trading partner, confirmed it had an outbreak of the disease earlier this month, while China was forced to cull 50 per cent of its pork production, federal Agriculture Minister Bridget McKenzie says.
"We are doing everything we can to ensure African swine fever does not reach our shore," she told Sky News on Sunday.
