Senator HANSON (Queensland—Leader of Pauline Hanson's One Nation) (14:28): My question is to Senator Reynolds, the Minister for the National Disability Insurance Scheme. Minister, in 2011, the Productivity Commission estimated a national disability insurance scheme would cover 411,000 participants at a gross cost of $13.6 billion when fully implemented. A half-a-percentage-point rise in the Medicare levy was introduced in the 2013 budget to help fund it. It is now forecast that the cost of the scheme will rise to a staggering $30 billion plus by 2024-25, with a projected 530,000 participants, costing more than the Medicare costs for the whole nation, and could blow out to $130 billion by the 2030s. Minister, what is the government going to do to rein in the cost of the NDIS so that it is sustainable and affordable to taxpayers?
