Mr HAMILTON (Groom) (14:59): My questions to the Prime Minister and concerns his failure yesterday and today to stand by his previous commitments to voice, treaty and truth. Last time Labor was in power its then prime minister, a mentor to the current Prime Minister, described climate change as 'the greatest moral challenge of our time' and then walked away from his commitment. Is this Prime Minister doing the same thing on voice, treaty and truth? The SPEAKER: Order! There is far too much noise. There was a question in there.
