Senator GALLAGHER (Australian Capital Territory—Minister for the Public Service, Minister for Finance, Minister for Women, Manager of Government Business in the Senate and Vice-President of the Executive Council) (14:25): I think the answer to that is that we're not looking at that. We're not looking at banning them. PwC is an individual company or contractor. We are interested, in a general sense, in looking at how we can enhance the integrity of the engagement the Commonwealth has with suppliers, and we are developing a Commonwealth supply code of conduct. That will outline the behavioural standards that are expected from suppliers during procurement processes and while under contract. This is something that we're looking at prospectively. Some of the work that was done around the original PwC and Tax Practitioners Board issue, and the advice taken through that, was not about being able to end any contract with PwC. That wasn't available to the Commonwealth. The PRESIDENT: Senator Pocock, a second supplementary?
