Senator AYRES (New South Wales—Minister for Industry and Innovation and Minister for Science) (15:03): In question time earlier in the week, on 1 September, I undertook to provide further information in response to questions about the Darwin liquefied natural gas tank methane leak asked of me by Senator Waters in my capacity as the Minister representing the Minister for Resources. I've written to Senator Waters to provide additional information, and I table my letter to the Senate for the information of all senators.
