The Prime Minister told media in six different press conferences from 7 May that Australia had raised the incident 'at every level' with the Chinese government. He said, 'We've made the appropriate diplomatic representations,' and, 'We won't be shy about taking the opportunities to raise these issues, to make the strongest representations possible.' Can the minister please inform the Senate which ministers have sought or conducted calls with their Chinese ministerial counterparts since the incident on 4 May?
