Senator ABETZ (Tasmania—Leader of the Opposition in the Senate) (14:56): Mr President, I ask a supplementary question. I remind the minister that the most children in detention were under the Keating government and now the Gillard government. I ask the minister: are there any fundamental non-negotiable preconditions for minors and women in relation to the Malaysian deal? Opposition senators interjecting— The PRESIDENT: Senator Abetz, will you just go back? I missed the last part of your question because people on your side were trying to talk over you. Senator ABETZ: Thank you, Mr President. If I may, I will repeat the question and remind the minister that it has been the Keating and Gillard governments that have had the most children in detention. But what non-negotiable preconditions have been sought from the Malaysians to ensure that minors are protected? It is all well to talk about 'the deal', but surely there must be some fundamental preconditions that are non-negotiable. Are there any such preconditions that have been put to the Malaysians?
