One Nation, a fringe political party in Australia, has wielded significant influence over public policy for over 30 years without ever holding government or opposition status. Experts like public policy analyst Josh Sunman explain that the party's ability to shift the national conversation compels major parties to adopt sanitized versions of its policies to retain voters. Immigration is a prime example, as demonstrated by former Prime Minister John Howard's shift in rhetoric during the 1990s, aligning more closely with One Nation's views. The influence of One Nation is echoed globally, with political scientists noting similar dynamics in countries like the UK, where figures such as Nigel Farage have pressured major parties to adopt stricter immigration policies. This discussion is further explored in episode 4 of the podcast, The Making of One Nation, available on major platforms like Spotify and Apple.
