Major gun and hate speech reforms are expected to be waved through parliament in near-record time after MPs held late meetings to thrash out a deal on the contentious changes.
Labor will introduce legislative changes to clamp down on groups that voice hate against people of other faiths, bring in stronger background checks for firearm owners and set up a national gun buyback.
Debate on the overhaul, which follows December's Bondi Beach mass shooting, will begin in parliament on Tuesday morning. Prime Minister Anthony Albanese wants the reforms to pass on the same day.
Labor originally planned to introduce the gun and hate speech reforms in a single package, but was forced to split the bill due to fierce opposition to proposed racial vilification laws from the coalition and the Greens.
After the prime minister and Opposition Leader Sussan Ley discussed the reforms on Monday morning, Liberal MPs met in the evening to formalise their position ahead of a joint partyroom meeting with their coalition partner the Nationals on Tuesday.
Liberal sources told AAP on Monday night their party had put forward a series of technical amendments which had been accepted by Labor.
The changes include tightening the definition of a preacher or religious leader, introducing mandatory two-year reviews of the legislation and requiring consultation with the opposition leader when listing an extremist organisation.
Nationals MPs still have concerns about the impact the reforms could have on free speech.
The Greens have said they will not back the hate speech legislation due to the effect it could have on political commentary including protests, leaving the coalition as the only viable partner to pass the bill through the Senate.
While provisions making it illegal to vilify someone based on their race have been dropped, the watered-down legislation would still allow the government to effectively outlaw groups that promote hatred, likely including neo-Nazi organisation the National Socialist Network and radical Islamist collective Hizb ut-Tahrir.
The proposed laws would also allow the government to refuse or revoke the visas of people who hold extremist views.
Opposition home affairs spokesman Jonathon Duniam on Monday night praised elements of the bill allowing the government to shut down hardline extremist groups.
"I think there is space for increasing capacity to crack down and clamp down on some of these groups," Senator Duniam told Sky News.
"That is a small part of what the government should be doing."
Nationals leader David Littleproud said he supported the provisions allowing extremist preachers' visas to be cancelled, but negotiations with the government were ongoing.
"There are elements that we want to support, but there are other elements that obviously we have serious issues about," he told the ABC's 7.30 program.
Mr Albanese said if the legislation did not pass parliament this week, there would not be another chance to deal with it.
"We're not a government that puts things up over and over again to see them defeated," he told ABC Radio on Monday.
