Acting Health Minister Katy Gallagher said the eligibility criteria for another booster allows people with cancer and other complex health conditions, or those living with a disability extra protection from the deadly virus.
"The idea behind expanding the criteria has been to ensure that people who are at the greatest risk of severe infection, the worst end of Covid, are protected," she said.
In March, people aged over 65, residents of aged care or disability care facilities, immunocompromised people and Aboriginal and Torres Strait Islander people aged 50 years or above were approved for a booster jab.
ATAGI also encourages people to be vaccinated against Influenza, which can be co-administered with the additional booster dose of Covid vaccine.
Asked whether a fourth dose would soon be recommended for the general population, Ms Gallagher said that "ATAGI's view at the moment is that's not required."
