Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:47): Mr President, I ask a supplementary question. In light of his comments, and in light of the Minister for Agriculture's comments—'A $1 billion dollar threshold for foreign investment screening is an absurdity'—I ask the minister, can he explain the policy rationale for the $1 billion threshold that remains applicable to the purchase of agricultural land by investors from the United States, Chile and New Zealand? And will he rule out renegotiating any of those agreements?
