Senator Sterle, I completely reject the premise of your question. Two independent reviews, by PricewaterhouseCoopers and Jaguar Consulting, concluded that the road safety remuneration system, including the tribunal, was not required, given that there is limited evidence of a link between safety and remuneration. In fact, the PricewaterhouseCoopers review found that the orders made by the tribunal would cost the economy in excess of $2 billion over 15 years.
