Earlier this month, the Prime Minister agreed to a parliamentary inquiry into whether section 18C of the Racial Discrimination Act imposes unreasonable restrictions on freedom of speech.
It makes it illegal to "offend, insult, humiliate or intimidate" because of a person's "race, colour, national or ethnic origin".
Rod Little, from The National Congress of Australia's First Peoples, is among almost a dozen representatives from community groups who've visited Canberra this week to make their message clear.
They want the Racial Discrimination Act left alone.
