Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (15:00): I thank Senator Rennick for his first supplementary question. I wasn't present during those questions, I don't believe, but I shall make contact with the CSIRO and seek to get an answer to your question as quickly as I can, Senator Rennick. The PRESIDENT: Senator Rennick, second supplementary?
