Senator NASH (New South Wales—Deputy Leader of The Nationals in the Senate) (14:44): Mr President, I ask a supplementary question. I refer to the tabling of the FIRB's 2011-12 annual report last Friday. That report showed that levels of foreign investment in agriculture since 2007 have averaged $2.5 billion per year compared to an average of just $274 million per year in the 10 years before 2007. Why has the government presided over such a large increase in foreign investment in Australian agriculture without taking any policy action to tighten the monitoring of foreign investment that occurs in our farming sector?
