Senator PATRICK (South Australia) (14:23): Sorry, Minister, you didn't really go to the intersection of CU-River Mining's operations in the Woomera Prohibited Area. But I'm also interested that CU-River Mining have procured an area near Port Augusta for transhipment. That may involve the introduction of Chinese vessels into the Spencer Gulf. Noting that the Cultana Training Area is nearby, are there any risks and what is Defence doing in respect of that risk?
