Senator RUSTON (South Australia—Minister for Families and Social Services and Manager of Government Business in the Senate) (15:38): I seek leave to make a short statement. The PRESIDENT: Leave is granted for one minute. Senator RUSTON: The government welcomes the recent report from the Senate Standing Committee on Rural and Regional Affairs and Transport concerning water quality outcomes in the Great Barrier Reef and will respond in due course. This is a subject the government takes very seriously, with water quality outcomes being a major focus in the government's reef 2050 plan and the unprecedented $1.9 billion investment in the reef over the next decade. Committee hearings can at times involve robust exchanges by senators on all sides. It is incumbent on all senators to undertake their duties in a respectful manner, in line with the standards laid down by the Senate.
