Senator FARRELL (South Australia—Deputy Leader of the Opposition in the Senate) (14:22): Mr President, I have a supplementary question. The Members of Parliament (Staff) Act, associated directions and guidelines and the Prime Minister's Statement of Ministerial Standards set out various requirements related to the appointment of ministerial staff. Who carried out checks against these requirements when appointing Deputy Prime Minister Joyce's former media adviser to positions in the offices of Minister Canavan and Nationals whip Damian Drum?
