Senator JOYCE (Queensland—Leader of The Nationals in the Senate) (14:33): Mr President, I ask a supplementary question. I refer the minister to the fact that the government justified its approach to stimulus in 2009 by relying on a draft, unpublished overseas paper by Christian Broda and Jonathan Parker. Can the minister explain why the government relied on a draft, unpublished, overseas paper to spend $8 billion in 2009, but will not accept the findings of a Treasury finance paper today?
