Tiles were thrown at officers who deployed a Taser during the standoff yesterday afternoon.

Meanwhile, inside the home, 47-year-old Richard Garland was bleeding to death after he was allegedly stabbed in the head.

Tactical police swarmed Garland's Goonoo Goonoo Road property around 4.30pm yesterday.

Police said after locking himself inside a bedroom Nielsen emerged through the roof, wielding a knife.

When officers fired bean bag rounds, feathers exploded from his puffer jacket but the 55-year-old didn't seem fazed.

Moving onto the roof, negotiators tried to reason with him but when they got too close, he fled.

After eventually falling from the roof, he was disarmed, arrested and taken to John Hunter Hospital, where he remains under police guard.

No charges have been laid.

The street remained shut down today as forensic and homicide detectives took over the investigation, and floral tributes were laid for Garland.

New research has provided a new sign of just how hard the Sydney housing market is for singles. 

Comparison site Compare the Market discovered solo wage earners were being locked out of the city's property market.

It found of Sydney's 635 metropolitan suburbs, not one was affordable for a single person earning a median weekly income of $1416.

On that income, a solo property owner would have to spend more than 30 per cent of their wages servicing a loan, putting them in mortgage stress.

"This includes putting down that 20 per cent deposit, and for many that is out of reach already," Compare the Market's Chris Ford said.

"But then you've got to include not just those mortgage repayments but insurances, rates, ongoing maintenance that might be required as well … and an already stretched budget is really pushed to its limit."

It's a little easier for couples but the analysis found only 126 suburbs were affordable on a two-person income.

This includes the likes of Cabramatta, Liverpool, Mt Druitt, Berkley Vale and Carramar.

Corelogic data shows the median house price did fall slightly in the past quarter, but it still stands at almost $1.5 million ($1,474,032.)

Unit prices also dipped sljghtly, however the median price remains at almost $860,000 ($857,969).

Most property commentators believe house prices will rise if interest rates continue to fall.

Pope Francis has rested during a peaceful night following a respiratory crisis and blood transfusions, the Vatican says.

Vatican spokesman Matteo Bruni's one-line statement on Sunday morning (Sunday evening AEDT) didn't mention if Francis was up or eating breakfast.

The brief update came after doctors said the 88-year-old pope, who had part of one lung removed as a young man, was in critical condition.

On Saturday morning, he suffered a prolonged asthmatic respiratory crisis while being treated for pneumonia and a complex lung infection.

The pope received "high flows" of oxygen to help him breathe. He also received blood transfusions after tests showed low counts of platelets, which are needed for clotting, the Vatican said in a late Saturday (Sunday morning AEDT) update.

The Saturday statement also said that the pontiff "continues to be alert and spent the day in an armchair although in more pain than yesterday".

Doctors said the prognosis was "reserved".

Doctors have said Francis' condition is touch-and-go, given his age, fragility and pre-existing lung disease, and that the main threat facing him is if the infection enters the bloodstream, a serious condition known as sepsis.

A major air and sea search is under way for a fisherman believed to have been taken by a shark off the NSW coast.

The man was taking part in a state-wide interclub fishing competition today off the coast of Port Stephens near Newcastle when he was reportedly attacked by a great white shark after falling off his boat.

Crews from the NSW Water Police, Marine Rescue NSW as well as the Life Saver Rescue helicopter were searching the area 55 kilometres off the Newcastle coast, north of Sydney.

About 50 fishing vessels also joined.

The man fell overboard aboout 1pm, with emergency services called 35 minutes later, NSW Police said.

Inspector Paula Steer from NSW Ambulance said paramedics were on standby.

"We are using all of our resources to hope for a positive outcome," Steer said.

Fishing competitions are popular off this part of the NSW coastline.

Just a week ago, a group of anglers came face to face with another white shark in another competition in the same location, with the shark getting away with half of their catch.

The person who died had meth and cannabis in his system, the defence emphasised.

It's less than two months into 2025 and already 17 lives have been lost on South Australian roads.

Driving while distracted has increasingly become one of the biggest crash causes.

Police have released staggering images from the phone detection cameras of just how dangerous some drivers can be.

One has a mobile in one hand and fast food in another, neither on the wheel.

Another appears to be holding a beer.

Police Minister Stephen Mullighan said "nothing could be more dangerous behind the wheel".

"You are effectively driving blind folded if you are paying attention to your phone rather than paying attention to the road," he said.

The distraction of a mobile phone is just one of the ways in which drivers are failing to take responsibility at the wheel.

"Distraction can be many things. It can be using your mobile phone, it can be turning around to talk to the kids in the back to stop them fighting, turning to talk to someone in the passenger seat," acting Superintendent Jaimi Burns said.

A total of 91 lives were lost on South Australians roads last year.

More than half of those crashes involved speeding, distraction or dangerous driving.

Another 847 people were seriously injured.

Drug driving leads when it came to crashes in regional areas, and in an alarming number of motorbike crashes.

Pedestrians also make up too much of the road toll.

Now is one of the busiest periods for pedestrians on Adelaide roads amid the Fringe festival.

Police are ramping up patrols at Fringe hotspots targeting speeding and drink driving.

"For pedestrians, cyclists and other vulnerable road users, everyone has a role to play when it comes to being safe, on and around our roads," Mullighan said.
