Senator COLBECK (Tasmania—Minister for Sport and Minister for Senior Australians and Aged Care Services) (15:02): As I indicated a moment ago, the Prime Minister was reinforcing the agreement that he has made with state and territory leaders to start opening the economy at certain points of vaccination rate. To reinforce that, the national cabinet has asked the Doherty institute to do some further work on the modelling. But our aim is to work with the states and territories in a cooperative manner to reinforce the need to get vaccinated and to provide the opportunity for Australians to take up vaccination and reduce community transmission of the virus so that we can reopen both our communities and our economy, which we know is what all Australians want. That's what we will continue to do. The PRESIDENT: Senator Watt, a final supplementary question?
