Senator BOB BROWN (Tasmania—Leader of the Australian Greens) (15:05): Mr Deputy President, congratulations on your first ascension to the chair after your vote this morning. I draw your attention to the fact that question on notice No. 4 to the minister for climate change and No. 340 to the Minister for Foreign Affairs have not been answered. Although I have not sought an answer to question No. 660 from the Special Minister of State that is also beyond 30 days without an answer. If answers are not forthcoming I will seek to take further action in the sitting of parliament after the winter break. The PRESIDENT: Does any minister wish to provide an explanation to Senator Brown? If not, we will move to the motions to take note of answers.
