In all instances the recommendation for a booster is for people whose most recent COVID-19 vaccine or infection was six months or more ago, irrespective of how many prior doses that person has received.

For this booster dose, all available COVID-19 vaccines are anticipated to provide a benefit. However, Omicron-specific mRNA booster vaccines are preferred over other vaccines.

The recommendation for additional boosters came into effect on February 20.

Quotes attributable to Member for Bendigo, Lisa Chesters: 

“As of now, all adults who haven't had a booster or COVID infection in the past six months can go out and get a booster shot, to give them additional protection. 

“Whether it’s your fifth vaccine or your third or fourth, the protection will be beneficial as the weather cools down and we head into winter. 

“The Government has secured millions of doses of Omicron-specific boosters and encourages all eligible residents to book in for their jab.”
