Senator BIRMINGHAM (South Australia—Minister for Finance, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:03): The government has been working, as I said, carefully with New South Wales in relation to providing them support, and encouraging them at times to accept support, in relation to the application of the current lockdown and ensuring its success. In terms of the pathway out of crisis, we have also, for the nation, developed the work that's being released by the Doherty Institute, the type of modelling and work that is world-leading in terms of identifying how it is we can ensure that, as the vaccine rollout continues to progress across the country, we have informed evidence based approaches to be able to reduce the scale, scope or necessity of lockdowns in the future. That is a crucially important piece of work to inform us against the delta strain and the enormous additional challenges that that delta strain poses in New South Wales, as it does in many other parts of the world. The PRESIDENT: Senator O'Neill, a final supplementary question?
