One Nation leader Pauline Hanson backs Western Australia GST split after earlier opposition

Senator Pauline Hanson, who once labeled the 2018 GST deal as giving Western Australia an outsized benefit, has publicly endorsed the same carve-up, saying it supports business and mining in the state. The shift aligns with her increasingly close association with billionaire Gina Rinehart, a Western Australian native who has provided significant financial support to One Nation, including gifting Hanson a plane. Prime Minister Anthony Albanese has reiterated that the GST agreement will remain in place until 2029, and a final Productivity Commission report is expected before the end of the year.

Queensland Treasurer David Janetzki welcomed the report, claiming it proves the state has been denied its fair share. Meanwhile, Western Australian Premier Roger Cook dismissed the Commission’s interim findings as unreliable and urged other states to leave WA’s GST arrangement untouched.
