Senator BIRMINGHAM (South Australia—Minister for Trade, Tourism and Investment and Deputy Leader of the Government in the Senate) (14:21): I thank Senator Steele-John for the historical undertaking, lecture or otherwise in relation to the purpose of strike actions and why it is that people may engage in civil disobedience. Our position is quite clear: the actions of students in doing so do mean that the potential is that additional costs are incurred in having to reschedule lectures, particularly in the case of medical students, where there are expectations that the courses they're undertaking are, of course, fully received and that students need to act there. The disruption is also to fellow students in that regard as well. Ultimately, this is a choice for individual students, but we've made very clear there's nothing wrong with having a say but do it in your own time. The PRESIDENT: Senator Steele-John, a final supplementary question.
