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.
It was in the evening that the bombing started to intensify.
Salah Jundia, his father and brothers huddled together in their home in Shujaiyya, just east of Gaza City, trying to work out what to do.
It was too risky for them to leave at night. There were a lot of them too. Extended family living across four storeys. They decided they would wait until after dawn prayers.
The explosion tore through the building just before 5am, collapsing one storey on to the next.

Jundia says he survived because pieces of bedroom furniture fell on top of him.
Then he looked for his father and brothers.
“I found one of them calling for help. I removed the rubble covering him with my hands. Then I saw another brother covered in rubble but he was dead,” he told Sky News.
Jundia added: “My father was also dead. My other brother was also dead. We got them out and that is when I saw that the whole building had collapsed.”
Over the next few hours, they scrambled to rescue who they could.
An aunt and uncle and one of their children, Shaimaa. Uncle Imad and his son Mohammad. The bodies of Montasir and Mustaf.

Jundia says he could hear cries for help, but they were coming from deep in the rubble and were impossible to reach.
The rescue teams on site – civil defence they are called – did not have the kit to clear through three floors of 500 square metres, 30cm slabs of concrete.

In the afternoon, Jundia says Israel’s Defence Forces (IDF) told rescue teams to leave as they would be resuming their bombardment.
Jundia buried the bodies he had managed to pull out but he knew 15 of his family members, 12 of them children, were still somewhere inside the rubble, still crying for help.
He made a desperate video appeal, begging the Red Cross and Arab countries to pressure Israel to grant access to the site. It was picked up on a few social media accounts.
Israel won’t allow heavy equipment into Gaza. No diggers or bulldozers, nor the fuel or generators to run them.
They say it will fall into Hamas’s hands.
It was a major sticking point during the ceasefire and it is a major issue now as the bombardment continues, given the fact that hundreds if not thousands of civilians might survive if there were the equipment to extract them.

Civil defence trying to get to the Jundia family home over the next few days were halted because the IDF were in the vicinity. A family friend tried himself and was killed.
The footage that our camera teams have shot in Shujaiyya over the past two weeks shows how civil defence teams struggle to save those who are trapped and injured with the most rudimentary of equipment – plastering trowels, sledgehammers, ropes and small drills.
“The tight siege stops civil defence equipment from getting in,” says one.
They added: “So we are taking much longer to respond to these events. Time is a factor in getting these people out. So we call immediately for the necessary equipment to be allowed in for the civil defence to use.”
The IDF say they are investigating the circumstances around the Jundia family as a result of our enquiries.
In relation to the access of heavy equipment into Gaza, they say they work closely with international aid organisations to enable the delivery of humanitarian activities in accordance with international law.
The last contact Jundia had from beneath the rubble was a phone call from his uncle Ziad, three days after the strike.
“The line was open for 25 seconds then it went dead. We don’t know what happened. We tried to call, but there was no answer,” he says.
He and his family were displaced several times before they returned home to Shujaiyya – to Rafah in the south, then Khan Younis and Deir al-Balah.
Along the way, Jundia lost one brother and a nephew to Israeli bombs.
“We were happy and all the family came back. We went back to our house. It was damaged, but we improvised and we lived in it. We have nothing to do with the resistance. We are not interested in wars. But we have been gravely harmed,” he says.
China’s economy performed better than expected in the first quarter of the year – but it reflects a moment in time before the explosive trade war with the US, which has seen the world’s two biggest economies effectively decouple.
Economists had predicted that gross domestic product would grow by about 5.1% in January to March, compared with a year earlier. In the end, it grew 5.4%.
But these impressive figures obscure the very serious challenges China’s economy is facing in the wake of Donald Tump’s trade war – and it is almost certain growth will not remain this strong as the year goes on.
