The 2025 federal election resulted in some unexpected outcomes, including the loss by the Greens Leader, Adam Bandt, of his seat in the House of Representatives. The new Greens leader is Senator Larissa Waters.
Does it matter that a party leader sits in the Senate, and why do the leaders of major parties almost always come from the lower House?
The answer is that by convention, rather than an express constitutional requirement, the prime minister sits in the lower house of parliament. Parties with aspirations to form government therefore choose leaders from among their members in the lower house.
