Senator McKENZIE (Victoria—Minister for Agriculture and Leader of The Nationals in the Senate) (14:27): Thank you, Senator Roberts, for your question and your ongoing interest in ensuring that the Murray-Darling Basin Plan rollout meets the needs of irrigators, the environment and the communities contained within the basin. As Minister Littleproud has made very clear, our government continues to work with state governments to roll out the plan in a way that least impacts on the ongoing financial viability of our agriculture sector and the communities that service that sector. And they're going through a very tough time. In your home state, sections of the Murray-Darling Basin proper have been in drought for upwards of six years. Right throughout the basin in New South Wales, again, drought is biting hard. It is difficult to have enough flows for high-security and low-security water entitlement holders when there is not enough water in the basin to go around. To that end we have been able to negotiate, with Minister Littleproud securing agreement from state governments, a socioeconomic detriment test before any further water is to be removed from basin communities. That actually ensures there can be no further negative social outcomes or economic outcomes for these basin communities before more water is taken out. That is incredibly important because these communities are doing it tough at the moment, and we need to ensure that their ongoing viability is secured not just for those towns and businesses but, indeed, for the broader export task and sustainability of our nation's economic position, and the role that agriculture and the Murray-Darling Basin producers play in that. The PRESIDENT: Order! Senator Roberts, a supplementary question?
