Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (14:12): If there is something that the emergence of the omicron variant should reinforce to all Australians and all those around the world, it is the importance of vaccination. It is the importance of encouraging all Australians to be vaccinated. Whilst from the outset our government has always said that vaccination should be voluntary and that we would not enforce mandates, except for working with the states and territories in relation to those areas of highly vulnerable individuals such as in aged care, disability care, and health practice, we absolutely encourage every Australian to get vaccinated. I urge every member across this parliament to engage in such encouragement as well. More than 19 million individual Australians have had at least one dose of the vaccine to date. That is an incredible turnout by Australians, who now count among some of the most highly vaccinated populations in the world. The PRESIDENT: Senator Keneally on a point of order? Senator Keneally: Yes, on direct relevance. I draw the minister back to the question. His answer here is not relevant to the question. It was very specific. Why did four members of the government appear on this webinar? The PRESIDENT: You've brought the minister back to part of the question. There was an additional statement at the beginning of the question about the omicron variant. I'm listening carefully to the minister. You've had the chance to bring him back to the question. Minister, you have the call. Senator BIRMINGHAM: As I said before, I encourage and the government encourages every member of the government, of the crossbench—of the parliament—to encourage vaccination and to encourage its take-up. I urge all members to do so, and it is the urging and the health advice from across the country that has helped to achieve 92.4 per cent of Australians over the age of 16 having had at least that first dose. That's 92.4 per cent of Australians who have heeded that message and who are out there, having been vaccinated, getting vaccinated, and building those numbers day in, day out. We will continue to work to lift those numbers and to grow those numbers as high as possible. (Time expired) The PRESIDENT: Senator Keneally, a supplementary question?
