One Nation proposes mandatory regional service requirements for Australian-trained GPs before they can access Medicare bulk billing incentives in metropolitan areas, with Barnaby Joyce advocating for up to 10 years of regional service. The government's Social Services Minister Tanya Plibersek defends Labor's approach of investing $816 million in GP training with half of training places in regional areas, plus increased bulk billing incentives and 33 new endometriosis clinics. The debate centres on competing solutions to address doctor shortages in regional and remote Australian communities, with disagreement over whether incentives or mandatory service requirements are more effective.
