The 29-year-old was helped by residents in the area – including a local vet who had just purchased a set of bandages, which she used to create a tourniquet to stem the bleeding.
Surgeons worked through the night to save Ms O’Neill’s leg from amputation, according to Sydney’s Daily Telegraph.
She is expected to make a full recovery.
In a statement, released through the hospital where she is being treated, Ms O’Neill thanked her “heroic and very kind neighbours for the critical assistance they provided her”.
She added that her likely recovery was a “testament to their extraordinary skills”.

Woman injured in Sydney shark attack
Police in New South Wales said Ms O’Neill suffered a “serious injury” to her right leg during the attack, which is believed to have been carried out by a bull shark.
The incident happened about 20 metres from a jetty in Elizabeth Bay, an upmarket inner-city suburb near the iconic Sydney Opera House and the city’s central business district.

Shark sightings along Sydney’s ocean-facing beaches are common, and the harbour is known to be an important habitat for bull sharks and their young.
However, shark scientist Amy Smoothey said attacks in the area were “really rare”.
“The last incident that occurred in Sydney Harbour was in 2009,” she told the Australian Broadcasting Corp.

Known for their aggressive, territorial nature, bull sharks are large and usually found in warm, shallow waters, but can survive in fresh waters and are known to swim up rivers.
Bull sharks, great whites, and tiger sharks are responsible for most recorded unprovoked attacks on humans.

In 2009, an Australian navy clearance diver was mauled by a bull shark during a training exercise in the harbour. The shark tore off his arm and part of his leg.
Two people are dead and nearly 560 people were arrested after disorder broke out in France following Paris Saint-Germain’s victory in the Champions League final, the French interior ministry has said.
The ministry added 192 people were injured and there were 692 fires, including 264 involving vehicles.
A 17-year-old boy was stabbed to death in the city of Dax during a PSG street party after Saturday night’s final in Munich, the national police service said.
The second person killed was a man who was hit by a car while riding a scooter during PSG celebrations, the interior minister’s office said.
Paris police chief Laurent Nuñez has said the man was in his 20s and although the incident is still being investigated, it appears his death was linked to the disorder.
Meanwhile, French authorities have reported that a police officer is in a coma following the clashes.

The officer had been hit by a firecracker that emerged from a crowd of supporters in Coutances in the Manche department of northwestern France, according to reports in the country.
Initial investigations reportedly suggest the incident was accidental and the police officer was not deliberately targeted.
The perpetrator has not been identified.

The interior ministry earlier said 22 security forces workers were injured during the chaos – including 18 who were injured in Paris, along with seven firefighters.
In a news conference today, Mr Nuñez said only nine of the force’s officers had been injured in the French capital.
He added that fireworks were directed at police and firefighters were attacked while responding to car fires.
There were 559 arrests across the country during the disorder, including 491 in Paris. Of those detained across the country, 320 were taken into police custody – with 254 in the French capital.
Mr Nuñez said although most people wanted to celebrate PSG’s win, some only wanted to get involved in fights with police.
He also said the force is only at “half-time” in its response because the PSG team will be celebrating their Champions League victory on the Champs Élysées later today.

Mr Nuñez said that the police presence and military presence in Paris will be increased on the ground for the parade.
It comes after flares and fireworks were set off in the French capital after PSG beat Inter Milan 5-0 in Munich – the biggest ever victory in a Champions League final.
Around 5,400 police were deployed across Parisafter the game, with officers using tear gas and pepper spray on the Champs Élysées.

At the top of the Champs Élysées, a water cannon was used to protect the Place de l’Etoile, near the landmark Arc de Triomphe.
Police said a large crowd not watching the match tried to push through a barrier to make contact with officers.
Some 131 arrests were made, including 30 who broke into a shoe shop on the Champs Élysées.
Police have said a total of four shops, including a car dealership and a barbers, were targeted during the disorder in Paris.
Two cars were set alight close to Parc des Princes, police said.
PSG forward Ousmane Dembélé appealed for calm in a post-match interview with Canal+, saying: “Let’s celebrate this but not tear everything up in Paris.”

After the final played at the Allianz Arena in Munich, Germany, thousands of supporters also tried to rush the field.
Police lined up in front of the PSG end of the stadium at the final whistle, but struggled to contain the fans for several minutes when they came down from the stands following the trophy presentation.

Désiré Doué, the 19-year-old who scored two goals and assisted one in the final, said after the game: “I don’t have words. But what I can say is, ‘Thank you Paris,’ we did it.”
Despite being a supporter of PSG’s rivals Olympique de Marseille, French President Emmanuel Macron also said on social media: “A glorious day for PSG!
“Bravo, we are all proud. Paris, the capital of Europe this evening.”
Mr Macron’s office said the president would receive the players at the Elysee Palace on Sunday.

At least 26 people have been killed near an aid distribution centre in the Rafah area of southern Gaza, according to the Hamas-run Palestinian health ministry.
Earlier, a nearby hospital run by the Red Cross reported that at least 21 people had been killed. The hospital, which has been receiving bodies and the wounded, also said another 175 people had been injured.
Witnesses said the deaths came after Israeli forces opened fire at a roundabout near the Gaza Humanitarian Foundation hub, a new aid organisation backed by Israel and the US.
However, Palestinian and Hamas-linked media have attributed the deaths it has reported on to an Israeli airstrike.
It is not yet clear if eyewitnesses and Hamas-affiliated media are giving different accounts of the same incident.
Sky News has contacted the Israel Defence Forces (IDF) for comment.
Witnesses tell of shooting
The area where the reported shooting took place is controlled by Israeli forces.
Ibrahim Abu Saoud, an eyewitness, said Israeli forces opened fire at people moving toward the aid distribution centre.
“There were many martyrs, including women,” the 40-year-old man said. “We were about 300 metres away from the military.”
Abu Saoud said he saw many people with gunshot wounds, including a young man who he said had died at the scene. “We weren’t able to help him,” he said.
Mohammed Abu Teaima, 33, said he saw Israeli forces open fire and kill his cousin and another woman as they were heading to the hub.
He said his cousin was shot in his chest and died at the scene. Many others were wounded, including his brother-in-law, he said.
“They opened heavy fire directly toward us,” he said as he was waiting outside the Red Cross field hospital for word on his wounded relative.

Controversial new aid system
The Gaza Humanitarian Foundation (GHF) operates as part of a controversial aid system which Israel and the US says is aimed at preventing Hamas from siphoning off assistance.
Israel has not provided any evidence of systematic diversion, and the UN denies it has occurred.
The foundation’s distribution of aid has been marred by chaos, and multiple witnesses have said Israeli troops fired on crowds near the delivery sites.
UN agencies and major aid groups have refused to work with the new system, saying it violates humanitarian principles because it allows Israel to control who receives aid and forces people to relocate to distribution sites, risking yet more mass displacement in the territory.
Before Sunday, at least six people had been killed and more than 50 wounded, according to local health officials.

GHF says aid distributed ‘without incident’
The foundation says the private security contractors guarding its sites did not fire on the crowds, while the Israeli military has acknowledged firing warning shots on previous occasions.
The foundation did not immediately respond to a request for comment following the hospital’s claims.
In an earlier statement, it said it distributed 16 truckloads of aid early on Sunday “without incident”. It dismissed what it referred to as “false reporting about deaths, mass injuries and chaos”.
Meanwhile, the UN’s aid system has struggled to bring in aid after Israel slightly eased its total blockade of the territory last month.
Those groups say Israeli restrictions, the breakdown of law and order, and widespread looting make it extremely difficult to deliver aid to Gaza’s roughly two million Palestinians.
Experts have warned that the Palestinian territory is at risk of famine if more aid is not brought in.

From 29 May: Meet Gaza’s paramedics
The war in Gaza began when Hamas-led militants stormed into southern Israel on 7 October 2023, killing some 1,200 people, mostly civilians, and abducting 251.
They are still holding 58 hostages, around a third of them believed to be alive, after most of the rest were released in ceasefire agreements or other deals.
Israel’s military campaign has killed more than 54,000 people, mostly women and children, according to Gaza’s Health Ministry, which does not say how many of the dead were civilians or combatants.
The offensive has destroyed vast areas of the territory, displaced around 90% of Gaza’s population and left people almost completely reliant on international aid.
