We're going to close off our live rolling coverage of the Bondi Beach shooting.

Here's what made headlines today.

The final victim of the Bondi Beach terror attack has been identified as 68-year-old Randwick local Tania Tretiak.

The seven men dramatically arrested by heavily armed police in Liverpool last night have been released without charge.

Prime Minister Anthony Albanese has announced the largest gun buyback in Australia since the 1996 Port Arthur massacre, while NSW Premier Chris Minns has detailed his own state's firearm control and protest restriction laws.

Members of the public returned to Bondi Beach this morning after the crime scene lifted yesterday for a massive paddle out in memory of the 15 victims.

The 15th and final victim of the Bondi Beach terror attack has been identified as 68-year-old Randwick local Tania Tretiak.

The Sydney Morning Herald has reported she was attending the Chanukah by the Sea event with her family on Sunday night before the shooting began.

NSW Police Commissioner Mal Lanyon said earlier this afternoon that the seven men – all of whom were known to Victorian authorities – would be released today if there wasn't enough evidence to charge them.

The men had travelled from Victoria and Bondi "may have been one of a number of locations that the males were intending to attend, but the reason for attending is unknown," Lanyon had said.

He added that the exact threat posed by the group before their arrest wasn't known, but that police weren't prepared to take the risk of a violent offence being carried out.

One of the men spoke to 9News after his release, saying he hadn't done anything wrong and that the arrests were a misunderstanding.

He said he was in Sydney for a holiday.

All seven men who were arrested in south-west Sydney by heavily armed police in dramatic scenes last night have been released from custody without charge.

Police in NSW have just issued a warning, urging people to avoid protests over the coming days given the heightened tensions in the community following Sunday's attack.

"Now is a time for healing, unity and supporting one another," the statement read.

"While the NSW Police Force recognises people may want to protest due to recent events both here and overseas, we are asking the community to choose other ways to come together peacefully."

Police also promised to crack down on retribution or other violent behaviour, which has been promoted in some posts circulating on social media.

"We strongly encourage those planning or attending these events to reconsider," police said.

"There will be a significant policing response to any large-scale public gatherings, and this is not a time for large gatherings that may heighten tension or create further risk to the safety of the community.

"Anyone considering violence, retribution or vigilante behaviour should know that police will respond swiftly and decisively.

"The NSW Police Force will continue to take strong action against anyone who engages in criminal activity that is motivated by hate.

"We are committed to responding to all hate crimes. And we encourage anyone who is the victim of a hate crime or witnesses a hate crime to report the matter to police."

A protest will be held in Sydney next week against the new laws allowing police to ban protests in the wake of terror attacks, which were detailed by Premier Chris Minns earlier this afternoon.

Organisers Stop the War on Palestine and Jews Against the Occupation '48 say they will hold a "protest vigil" on Monday evening outside Sydney Town Hall in which they will mourn the victims of the Bondi Beach shooting and speak out against the new laws.

"After two years of attempts to ban or restrict protest in NSW, Premier Chris Minns is proposing tointroduce laws that will further restrict this democratic right," they said in a statement.

The protesters say they will also speak out to reject any link between pro-Palestine rallies and Sunday's terror attack.

"Palestinians and their supporters – including many Jews – have been on the streets for more than two years, peacefully but steadfastly opposing Israel's mass slaughter in Gaza, its violence in the West Bank, and its criminal attacks on Lebanon," they argued.

"Our call has been for an end to the genocide and Israel's impunity, not for attacks on Jews.

"Opposing genocide and the violation of international law is not antisemitic."

The Greens have announced their support for the government's weapons buyback, effectively ensuring any federal legislation related to the matter will pass parliament.

"We welcome the announcement of a gun buyback," party leader Larissa Waters said.

"There are now more guns in the community than before the Port Arthur massacre. It's time we built on the last gun buyback and strengthened our gun laws to keep communities safer – at the same time as tackling antisemitism, racism and radicalisation.

"The Greens will help to get guns off our streets, and so should every member of parliament. It should be above politics to stop the hoarding of these weapons that killed so many innocent men, women and children.

"A gun buyback with practical arrangements for surrender, secure collection, destruction and fair compensation would be a step in the right direction."

The Greens also called for laws similar to what was announced by the NSW government earlier this afternoon – limiting the number of guns a single person can own – to be introduced across the country.

"We welcome this move for a national gun buyback and it is important to tie it to structural changes in our gun laws that are grounded in community safety," Senator David Shoebridge said.

"No one in suburban Sydney, or anywhere in this country, should have a private arsenal of high-powered weapons at their home.

"There must be a clear cap on gun numbers, with multiple weapons only permissible where police are satisfied that there is a distinct requirement based on strict criteria.

"Recreational hunting, which is the reason used to obtain some of the largest caches of deadly weapons, needs to be removed as a basis for obtaining a gun licence."

The support from the Greens in the Senate, on top of Labor's significant lower-house majority, will give the government the numbers it needs to pass any legislation through parliament.

NSW establishes fundraiser with $1 million donationThe NSW government has established an official fundraising drive to support survivors and victims' families, kicking it off with a $1 million donation.

"Despite the unimaginable grief this attack has caused, we've seen some beautiful acts of humanity across our city," Chris Minns said in a statement announcing the initiative.

"We've seen long lines form around blood banks across the country, and community organisations handing out food at Bondi Beach.

"These quiet acts of humanity mean a lot, and donating is just another thing people can do if they wish."

The fundraiser is being run by the Rotary Australia World Community Service, and donations are tax-deductible.

The money collected will go towards a range of support, which the government said "may include immediate financial relief such as bereavement costs, medium-term recovery assistance, and longer-term needs including medical care, counselling and rehabilitation".

"The fund will also support longer-term healing initiatives for the Bondi community," it added.

Minns acknowledged the new anti-assembly provisions would arouse opposition.

He said it was not the government's intent to stifle protest.

"I'm firmly of the view that when we get to the point where you see passions enliven to the point that it can unleash violence in our community, we have to take action," he said.

"So it's extraordinary, it's under a terrorism designation."

He said he knew the laws would attract opposition and declarations of going "a step too far".

"I don't think it is," he said.

"I think right now, because of the combustible situation out there, if we did have mass protests with violent imagery and chants that we have seen, I think it would rip apart our community."

Minns said he felt a "deep responsibility" over the Bondi terror attack."

The profound responsibility of any government is to protect its citizens and that's not what happened on Sunday," he said.
