Reflecting the influence of the Westminster system, and in accordance with section 64 of the Constitution, Ministers are selected from the elected members of Parliament. In keeping with the convention of Cabinet solidarity, all ministers are expected to defend the collective decisions of Cabinet regardless of their individual views. Ministers who cannot undertake the public defence of government actions are expected to resign. Such resignations are rare; and the rarity also of public disclosure of splits within cabinet reflects the seriousness with which internal party loyalty is regarded in Australian politics.
