Senator McKENZIE (Victoria) (14:46): My question is to the Minister representing the Minister for Sustainability, Environment, Water, Population and Communities, Senator Conroy. Last week the New South Wales government announced a scientific trial of grazing would be conducted in river red gum and cypress forests in the Riverina area, on the land where grazing permits have been issued by the former Labor government— Honourable senators interjecting— The PRESIDENT: Order! Just wait a minute, Senator McKenzie. I cannot hear you because of noise in the chamber. Please continue. Senator McKENZIE: The trial will be based on a recommendation to the previous New South Wales government made by the Natural Resources Commission. Is the minister prepared to let this valid scientific trial proceed, or will Labor put politics and its sycophantic relationship with the Greens ahead of science and attempt to intervene in this state matter? Honourable senators interjecting— The PRESIDENT: Order! When there is silence we will proceed.
