Hon GRANT ROBERTSON (Minister of Finance): Thank you, Madam Chair, and I thank the member for his question. Obviously, we're looking here at Part 1, and in particular, I presume, the question relates primarily to the "Purposes" clause, clause 3. This is the third, as the member has indicated, in a trilogy of bills on the Reserve Bank. The first of those was the one that altered the objectives of monetary policy to include maximum sustainable employment and change the decision-making process for that to a committee-based process, in line with best practice around the world. These next two bills were also part of the review process, and I guess that's my starting point to answer the member's question—that after 30-odd years of operation of the Reserve Bank, we felt that it was timely to undertake a review. A lot has changed in monetary policy since that time.
