Senator MILNE (Tasmania—Leader of the Australian Greens) (14:10): My question is to the minister representing the Minister for Sustainability, Environment, Water, Population and Communities, Minister Ludwig. Is the minister aware of the wonderful news which has just come through that UNESCO's World Heritage Committee has listed an extension to Tasmania's Wilderness World Heritage Area of some 170,000 hectares following 30 years of campaigning from conservationists in Tasmania and around the world to protect the state's tall forests? If so, can the minister tell me what undertaking the government made to the UNESCO World Heritage Committee regarding further assessment of the area for its cultural values?
