A new investigative podcast series titled 'The Populist' has been launched to examine the political strategies and influence within Pauline Hanson’s One Nation party. The series, reported by senior correspondent Sarah Martin, aims to analyze the party's growth and its alignment with global populist movements, specifically noting a reliance on rhetoric critical of mainstream media outlets.

A central focus of the investigation is the extent of the influence held by billionaire benefactor Gina Rinehart over the party's decision-making and policy direction. The reporting suggests that the relationship between the party and Rinehart is significant enough to warrant public scrutiny, particularly regarding the party's long-term political objectives. While the investigation frames these connections as a matter of public interest, the party has not yet provided a detailed public response to the specific claims regarding the depth of Rinehart's involvement. The reporting also notes that the party's operational style mirrors tactics observed in other international populist movements, raising questions about the party's primary political allegiances and the interests it represents in the Australian landscape.
