Years of debate, led by conservatives within the Liberal party, over watering down Australia's race hate laws comes to a head today.
But what is today?
It's also known as "Harmony Day" in Australia, which according to the government is a "celebration of our cultural diversity – a day of cultural respect for everyone who calls Australia home".
Today the Coalition partyroom will reportedly debate taking out the words "insult, offend and humiliate" from the Racial Discrimination Act's section 18C and replacing them with the word "harass".
The proposal has vocal support among the party's far right, but many Liberal moderates who represent marginal seats with large ethnic communities are very worried.
Even if the changes pass the House of Representatives (there's reportedly been talk of Liberal MPs crossing the floor to vote against them), key Senate crossbencher Nick Xenophon has suggested he won't support it.
Without Xenophon and his team of senators, the 18C changes are doomed to fail.
