The ACTING DEPUTY PRESIDENT ( Senator Chandler ) (15:56): I inform the Senate that, at 8.30 am today, 18 proposals were received in accordance with standing order 75. The question of which proposal would be submitted to the Senate was determined by lot. As a result, I inform the Senate that the letter from Senator Ayres, proposing a matter of public importance, was chosen—namely: The refusal of the Morrison-Joyce Government to publicly release the Doherty Modelling, as Australians become increasingly concerned that the previous modelling based on a small COVID outbreak does not adequately deal with how many hospitalisations, deaths, cases are now expected with revised modelling. Is the proposal supported? More than the number of senators required by the standing orders having risen in their places— The ACTING DE PUTY PRESIDENT: I understand that informal arrangements have been made to allocate specific times to each of the speakers for today's discussion. With the concurrence of the Senate, I shall ask the clerks to set the clocks accordingly.
