Senator NASH (New South Wales—Deputy Leader of The Nationals in the Senate and Assistant Minister for Health) (14:56): Those opposite are aware of a range of changes in the budget relating to health. Those opposite are well aware why. The changes that have occurred in the budget are to ensure a sustainable health system into the future. The MBS 10 years ago cost $8 billion. It now costs $19 billion and we are on a trajectory to $34 billion. The government has taken the correct steps to ensure a sustainable health system. Senator Wong: Mr President, I rise on a point of order: on relevance. This minister, when asked a direct question, has a habit of saying, 'Those opposite are aware of a range of changes.' That is not the point of question time. She has been asked a very specific question about the higher bulk-billing incentive for doctors in regional areas and whether the budget has removed that. She should answer the question and, under standing orders, she is required to be directly relevant. The PRESIDENT: Minister, have you concluded your answer? I invite you to continue your answer. You have not concluded? You have concluded? Opposition senators interjecting— The PRESIDENT: Order! It is no wonder I cannot determine, because I cannot hear. Quiet on my left! Senator Nash, I will invite you to continue your answer and I will also remind you of the question.
