Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:01): Mr President, I ask a supplementary question. I refer to communications minister, Mr Turnbull, who says that while Australia must deal with the threat of terrorism, we: … have to do so within the rules … which above all, of course, sits the constitution with which we all have to comply. Does the minister share the Prime Minister's confidence that the legislation will 'minimise constitutional challenge'?
