After poaching one of his state MPs in her bid for Queensland domination, Pauline Hanson has some advice for Malcolm Turnbull on how to fix his government – bring Tony Abbott back to the cabinet.

Senator Hanson has emerged as one of Mr Abbott's biggest supporters since returning to parliament, the pair having buried the hatchet following his role in bringing about the downfall of One Nation in the late 1990s, when it posed a growing electoral threat to the Liberals.

But, speaking to Nine News on Tuesday, Senator Hanson took it a step further, campaigning for Mr Abbott's return to the front bench, once again as health minister.

"Bring Tony Abbott back into the portfolio," she said.
