Senator FISHER (South Australia) (15:28): Minister Wong has indicated that the department is using every endeavour to answer those questions by estimates and I look forward to that. I ask the Senate to note that answer. Question agreed to. Senator FISHER: Pursuant to standing order 74(5)—Senator Conroy knows what is coming—I ask Senator Conroy as the Minister representing the Minister for Sustainability, Environment, Water, Population and Communities for an explanation as to why not one of the 78 questions asked during additional estimates hearings of the Senate Environment and Communications Legislation Committee in February this year has been answered?
