Left-wing protesters are set to rally outside the National Press Club in Barton on Wednesday as One Nation leader Pauline Hanson delivers her inaugural leader's address.
Canberra Socialists executive council member Carter Chryse, who is organising the protest, said it was "disappointing" that Senator Hanson - who this month overtook Anthony Albanese as preferred prime minister in a Resolve poll - had been booked to speak.
"What we're seeing in Australia is a bit of the pattern [like] what's happened internationally ... Where racism, bigotry, scapegoating can take the place of just the ordinary right," Mr Chryse told The Canberra Times.
