The Greens have hosted a roundtable with representatives of a number of multicultural communities who are concerned about the Government watering down protections against racist hate speech.

Greens Leader Senator Richard Di Natale and Greens Justice Spokesperson Senator Nick McKim listened to concerns about the rise of racism across Australia.

"Representatives from across multicultural Australia and Aboriginal and Torres Strait Islanders were very clear - we must not make it easier to be racist," Senator McKim said.

The Greens will stand against the government's discriminatory anti-immigration agenda, and specifically against Minister Dutton's power grab through the Visa Revalidation Bill.

"This government has made it clear that they want to see an end to multicultural Australia," Greens Immigration spokesperson Nick McKim said.

"Peter Dutton, our anti-immigration minister, is seeking a further expansion of his powers so he can create two classes of Australian citizens, and undermine the security of all migrants living in Australia."
