Senator GALLAGHER (Australian Capital Territory—Minister for the Public Service, Minister for Finance, Minister for Women, Manager of Government Business in the Senate and Vice-President of the Executive Council) (14:31): This would have been work led by the TGA, but I will see if I can find further information about whether or not they were assisted by other laboratories. I imagine they were, as part of that work, but I will check and see if there's anything further I can provide to Senator Roberts. The PRESIDENT: Senator Roberts, a first supplementary?
