The Greens leader has put the prime minister on notice that his party would seek "in advance" to lock in a "stable and progressive" deal with Labor to form a potential minority government. Adam Bandt said a formal agreement with Labor would have "a lot of merit" in setting out the next parliament's priorities, including on the rental market, housing and free GPs. The prime minister says he plans to return to parliament in February to finalise bills such as electoral reforms.
