A fundraiser for Pauline Hanson’s One Nation in Melbourne tonight has been cancelled after anti-racism protesters threatened to demonstrate outside the venue.

One Nation leader Pauline Hanson has arrived in Perth to protests in the city’s east ahead of a sold-out sundowner on Wednesday evening.

Pauline Hanson is due to speak at a sold-out event at the Crooked Spire in Midland this evening, with an open agenda to touch on the budget, negative gearing, and migration.
