Senator LUDLAM (Western Australia—Co-Deputy Leader of the Australian Greens) (15:04): Pursuant to standing order 74(5), I ask the Minister representing the Minister for Resources, Energy and Regional Australia, Mr Frydenberg, for an explanation as to why answers have not yet been provided to questions on notice No. 2642 and No. 2907. For 2907, notice was given on 19 January of this year, so I acknowledge that it is only a matter of a week or so overdue. It relates to the transportation of radioactive materials through Australian ports from overseas. Notice of question 2642 was given on 24 November 2015. That is now months overdue. The question was around shipments of radioactive waste from France that have since returned to Lucas Heights in Sydney. I am seeking some explanation as to why answers to these questions are so vastly overdue.
