By the House (of Representatives), or in extraordinary circumstances by the head of state (currently the regent of the Commonwealth) but typically that requires the former to formally seek such a remedy from the latter.
I believe by convention the deputy PM in Australia is necessarily a member of this group (also called the Lower House), though our PM could in theory be a member of the upper house (aka the Senate). I don't believe that's ever been the case, though.
Fascinatingly our constitution mentions the role of Prime Minister precisely zero times -- it was assumed to be understood.
- jaza 4y agoGoing purely by our Constitution, technically all Ministers of State - that's all 42 people currently listed at https://www.aph.gov.au/about_parliament/parliamentary_departments/parliamentary_library/parliamentary_handbook/current_ministry_list https://www.aph.gov.au/about_parliament/parliamentary_depart... - equally share Executive power (and technically they themselves have no power, they can only advise the Queen, and her representative, the Governor-General, who are the ones with the actual power). However, as with everything in the Westminster system, the written law is only part of the picture, and by convention, we have one Minister to rule them all, and he/she exercises actual Executive power.
