Senator DI NATALE (Victoria—Leader of the Australian Greens) (14:26): Minister, when is the Prime Minister going to show a little bit of courage or some leadership—some guts—by calling for the disendorsement of Tony Abbott, whose only motivation seems to be to sacrifice the Prime Minister to the gods of his own bitterness and vengeance? Honourable senators interjecting— The PRESIDENT: Order on my right! Senator Bernardi, a point of order? Senator Bernardi: Yes. It's a point of order about addressing the former Prime Minister by his correct title, which is either 'the member for Warringah' or 'the former Prime Minister'. The PRESIDENT: Thank you, Senator Bernardi. It's timely to advise and remind all senators to address members and senators by their correct titles.
