Senator BIRMINGHAM (South Australia—Assistant Minister for Education and Training) (14:32): Whilst, as I understand it, Senator Wang is correct about that letter, I am advised that an amended request by the then environment minister, Mr Tony Burke, was submitted to the IESC on 17 April 2013—after the original request had been withdrawn. The amended request included reference to the water trigger—because the water trigger legislation had been introduced into the parliament by that stage. The amended request was submitted to ensure that the IESC advice to be provided did include consideration of that water trigger then before the parliament.
