A surge in popular support and voters' disenchantment with the political status quo has turned Pauline Hanson's One Nation into a powerful force in Australian politics.
The rise and rise of the once fringe political party, backed by Australia's richest person, threatens the Coalition's hold on regional seats and has put One Nation's policies high on the political agenda.
As voters turn to the party in growing numbers, Four Corners talks to former party officials and members who describe poor financial management and a lack of internal democracy, with a small group of people, including Pauline Hanson and National Director James Ashby, running the show.
And while Gina Rinehart's financial support for the party is well known, does her influence extend beyond fundraising and gifts?
One Nation has banned the ABC from a series of press conferences and refused to talk to Four Corners, but reporter Steve Cannane found a way to put questions to Senator Hanson as he investigates whether One Nation is ready for power.
Four Corners is the ABC's flagship investigative journalism program, delivering in-depth investigations into the issues, people and events shaping Australia and the world.
