Senator FIFIELD (Victoria—Manager of Opposition Business in the Senate) (15:00): Mr President, I ask a further supplementary question. I ask the minister—and to take it on notice if he needs to—whether the government will reconsider its rejection of Mr Abbott's proposal to establish a joint parliamentary committee, chaired by both sides of politics, to oversee the implementation of the NDIS—a proposal that would see the NDIS owned by the parliament as a whole.
