Tickets for the conservative forum, which includes a ballroom dinner with Trump, range from $US5000 ($7700) to $US25,000. Hanson has spent the week at Mar-a-Lago, crossing paths with figures such as former New York mayor Rudy Giuliani and bosses from tech firm Nvidia.

Hanson’s party has had ups and downs since she burst onto the scene in the 1990s attacking Asian immigration. Her party is currently polling at record highs (12 per cent in this masthead’s Resolve Political Monitor and 15 per cent in The Australian’s Newspoll) as she seeks to capitalise on concerns about migration at the same time as Opposition Leader Sussan Ley tries to tack towards the political centre. Hanson’s polling last time recorded higher levels of support than she recorded from voters at the election in May, indicating polling numbers might inflate her party’s popularity.

Joyce, the maverick former deputy prime minister, is openly flirting with joining One Nation, as first reported by this masthead, splitting Nationals colleagues between those happy to see him go and others worried about the damage he and Hanson could cause the Coalition.

Nationals leader David Littleproud has responded to the threat with new attacks on Hanson, casting One Nation as a “party of protest” that only knows how to express grievance.

“It’s easy to say no, but ultimately someone has to govern this country. If you don’t have alternative solutions other than no, then the country will see through that,” he said last week.

Hanson’s CPAC speech is filled with provocative talking points on diversity and inclusion, the climate change “hoax” and migration.

“Australia is taking in the same hateful, radical migrants from countries that are having an enormous impact on the UK and so many European nations right now and we’re seeing the impact with almost daily machete attacks, violent home invasions and weekly pro-Palestine protests across our major cities,” Hanson will say.

“It didn’t happen by accident, and if you speak out about it, you’re branded Islamophobic, racist, or even a nazi.”
