Australia gets 142,000 doses of Pfizer COVID-19 vaccine

Hunt expects the first phase of the rollout to take six weeks.

States have been told how many doses to expect but the Health Minister did not publicly release that breakdown.

"We'll provide that later on in the week; the states have been notified," he said.

Phase 1a includes aged care workers, vulnerable residents of aged care facilities, hotel quarantine workers, border staff and essential health care workers.

The federal government will control the vaccination plan for aged care residents and staff. Hunt, however, said it was up to states to decide which groups from that phase would take priority.

"It's a matter for the states, but they have indicated - and we generally support it - that the greatest immediate risk is the border quarantine process," he said. "They will make sure that the balance is focused on the greatest risk, and I think that's appropriate."

Prime Minister Scott Morrison said it was a historic day for Australia.

"One of the largest logistics exercises ever undertaken in this country has been planned for, Mr Speaker, and is now under way," he said during question time.
