Priorities have been set for the rollout of vaccines to help prevent more fatalities from the Japanese encephalitis outbreak.
There are 15 confirmed human cases of JEV in Australia - four in New South Wales, one in Queensland, four in South Australia and six in Victoria.
There are two confirmed deaths from it.
There's no surprise piggery workers are top priority for jabs along with those working on the front line trying to contain the outbreak.
There are expected to more announcements on the vaccine rollout this week.
Pigs are known to "amplify" the mosquito-borne disease, and have already infected more than 20 piggeries in Queensland, NSW, Victoria and South Australia.
The federal government on Friday agreed to spend $69 million on vaccines and mosquito management systems.
These first jabs will be supplied from the national stockpile of about 15,000 doses.
The government will spend almost $30 million buying more vaccines from across the world - enough for an extra 130,000 doses.
Health Minister Greg Hunt said those new vaccines would likely be secured over the next month.
Communicable Diseases Network Australia was given the job of figuring out the priority for the jabs.
The CDNA is joint initiative of the National Health and Medical Research Council and Australian Health Ministers' Advisory Council.
The following groups "have been prioritised" for vaccination:
People outside this list have been urged to contact their local public health authority to find out if they should have a JEV vaccine.
Australia has two vaccines approved for use - Imojev and JEspect.
These vaccines offer immunity of up to five years.
Public health authorities around Australia are warning residents in high-risk areas like along river corridors or in flooded areas the best way to prevent JEV is to cover up, use repellent and avoid being bitten by mosquitoes.
