Senator BIRMINGHAM (South Australia—Minister for Education and Training and Manager of Government Business in the Senate) (14:07): Because of the coalition government's tax cuts, Australians are going to keep more of their money, and they will get to keep even more of their money as long as there continues to be a coalition government in the future. But if those opposite are elected, Australians will be paying higher taxes. Opposition senators interjecting— The PRESIDENT: Senator Birmingham, please resume your seat. Order on my left! If I call order, take a breath and count to three before the interjections continue. Senator O'Sullivan? Senator O'Sullivan: Now that I'm on the frontbench, I'm even more keenly interested to hear what the senator has to say, and I can hardly hear it for the noises from the other side. Opposition senators interjecting— The PRESIDENT: Order on my left! Senator O'Sullivan is a lot closer to this end of the chamber now and should be able to hear, so I will ask for silence. Senator Collins on a point of order. Senator Jacinta Collins: On a point of order, I ask: what portfolio has been allocated to Senator O'Sullivan? The PRESIDENT: The minister made a statement earlier with respect to responsibilities. Senator Birmingham. Senator BIRMINGHAM: In relation to the tax cuts delivered for Australians, I want to pay tribute to the work of Mr Turnbull and the work of Mr Morrison but, importantly, to the work of Senator Cormann as well, in the delivery of those tax cuts for hardworking Australians, and indeed Senator Fifield in relation to media reform and Senator Cash in relation to the establishment of the Registered Organisations Commission and bringing back the ABCC. They have all delivered significant reforms that are important for ensuring that Australians keep more of their hard-earned dollars and for ensuring that Australians in the future will have a stronger economy with more jobs growth building on what is already record jobs— (Time expired) The PRESIDENT: Senator Hume, a final supplementary question?
