Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:00): I seek leave to make a short statement. The PRESIDENT: There being no objection, leave is granted. Senator WONG: We appreciate that there must be circumstances which have given rise to a very short period of notice, but I would like to again reiterate that it is important for question time that such notice is given as soon as practicable of ministerial absences.
