Senator PAYNE (New South Wales) (14:28): Mr President, I ask a supplementary question. I note the minister's response early in his answer about results. I would have thought, Minister, that the provision of performance data would help with checking on results. Can the minister further explain how it is possible that a performance indicator for the outcome that 'people have access to housing through an efficient and responsive housing market' has not been developed— Honourable senators interjecting— The PRESIDENT: Senator Payne, there were people on my left who were drowning you out, and I need to hear your question. To those on both sides: it is fairness to the person asking the question that they be heard in silence. Senator Payne, you can start again and the clock will be reset. Senator PAYNE: Thank you, Mr President. I note the minister's reference to 'results' in the beginning of his answer. I would have thought, Minister, that the provision of performance data would be a good indicator for results. Can the minister further explain how it is possible that a performance indicator for the outcome 'that people have access to housing through an efficient and responsive housing market' has not been developed in the 18 months since the National Affordable Housing Agreement was finalised?
