Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (14:07): Our national plan for reopening—which the Prime Minister drove, ensured we had the expertise of the Doherty institute to underpin and took through national cabinet—has relied upon Australians rolling up their sleeves to get vaccinated. And we thank them for doing that. In fact, they've become champions at it, delivering globally high vaccine rates across Australia. It is this that makes possible the safe reopening across our country. It's the incredible outcome made possible by all of the health workers and those who have risked their lives to help people suffering from COVID-19 but also to help to protect us all through the rollout of the vaccination program. That journey is not over. We are now one of first countries in the world to roll out a comprehensive nationwide booster program, to make sure that people can be as safe and as protected as possible. We've got access to more than 151 million additional doses, and the boosters will be freely available to anyone who is fully vaccinated. This is something we can all look forward to in 2022.
