Senator EDWARDS (South Australia) (14:59): Mr President, I ask a supplementary question of the minister. I refer the minister to the announcement that Deepak Fertilisers and Petrochemicals Corporation will not proceed with a proposed plant near Whyalla due, in part, to the cancellation of the Olympic Dam project. The plant would have created 400 jobs during the $350 million construction phase and 80 jobs during the running of the plant. How many more lost jobs and lost economic activity will there be as the negative impacts of these mining and carbon taxes now build momentum through the economy?
