The partner of missing Melbourne mother Ju 'Kelly' Zhang has been charged with her murder.

Joon Seong Tan, 35, was arrested at Tullamarine Airport about 6.15 on Wednesday night, allegedly trying to flee the state.

The arrest comes ten days after Ms Zhang's disappearance as ongoing investigations continue by police from the Missing Persons Squad, who spent today scouring a creek in Melbourne's inner north-east as part of their search.

Tan was previously arrested by police on Sunday afternoon and was later released without charge after 24 hours of questioning.

He earlier told police he last saw Ms Zhang outside her Epping home on Winchester Avenue about 5.30pm on Monday February 1, when the 33-year-old mother said she was going for a walk.

Ms Zhang, who hasn't been seen since, was believed to be wearing a pink nightgown and possibly pink slippers.

She did not have any personal belongings with her and police said her mobile phone was missing.

The phone was last active in the street, with a public appeal urging anyone who potentially finds it to contact police.

Police have also urged residents from Ivanhoe West, Epping and Doncaster to check their CCTV footage from the afternoon Ms Zhang went missing.

Investigators also want to speak to anyone who witnessed "suspicious activity" near Darebin Creek Reserve, near Seddon Reserve in Ivanhoe West on February 1 and 2.

Mr Tan is expected to face Melbourne Magistrates' Court on Friday.

A skydiver has serious fractures and suspected spinal injuries after neither of his parachutes opened.

The 32-year-old landed in a paddock in Wilton, in the Macarthur Region of NSW, and lost consciousness on impact.

CareFlight's Rapid Response helicopter landed at 2.15pm to meet NSW Ambulance paramedics giving treatment.

An ultrasound was taken to assess internal injuries and the man was given pain relief.

He has suspected spinal, pelvic and lower leg injuries.

NSW Ambulance Inspector Sylvia Malecki said the man "should buy a lotto ticket".

"He was extremely lucky not to sustain more significant injuries upon landing," Malecki said.

"Considering the scare the man just had, he was in reasonably good spirits.

"We urge thrill seekers to take every safety precaution possible when participating in extreme outdoor activities."

He was taken by road to Liverpool Hospital in a serious condition.

Victoria's hotel quarantine program is under further scrutiny after staff have appeared to be working without Personal Protective Equipment (PPE).

In vision exclusively obtained by 9News, a resident in hotel quarantine snapped an employee without a mask on.

Jeff Dalton is staying at the Intercontinental on Collins Street and took the photo of the worker today.

"There it was – no mask – and a nurse sitting in her little nurse's station again not wearing a mask," he told 9News.

"It doesn't give me too much confidence."

The problems do not stop there, with the Park Royal apparently relaxed in its processes as well.

Paul Roache visited the hotel on Sunday, January 24 to drop off supplies to a friend in quarantine.

"At no point did they ask me to scan in or ask for ID or QR codes," he said.

"I was a bit disappointed to say the least.

In the 15 minutes he was there, Paul used the elevator twice to access the Park Royal reception on level four.

"One of the staff members was in a full gown … the lift doors were closing and actually barged in and I had to hold the lift doors open to allow them to come in," he said.

Transport Infrastructure Minister Jacinta Allan today defended the state's system today.

"We're operating this program under the highest strictest of standards," she said.

Coronavirus Testing Chief Commander Jeroen Weimar said he would be "disappointed" if hotel quarantine staff were not following protocols.

"I'm sure if that were to be the case there would be very swift actions by my colleagues to deal with that."

"There are very tight controls about who can come in and out of a hotel quarantine hotel," he said.

Today authorities confirmed the Holiday Inn cluster had grown to 11 after two spouses of infected workers were confirmed this morning and an assistant manager at the hotel tested positive this afternoon.

Quarantine Victoria have said they take any breaches extremely seriously and they are reviewing CCTV following the allegations in the photo taken.

QCV said the pathology nurse may have been wearing a light pink mask which may not show up in the CCTV.

As to Mr Roache's story, the hotel quarantine body is adamant no breaches occurred and he was there for about five minutes.

While his name, number and details were not taken, they did know he was coming and his details were stored in a log as a delivery person.

He was in a lift with a member of the quarantine team but authorities say as long as social distancing was being practiced, this is allowed.

A fish is at the heart of some groundbreaking research helping Australian scientists to unlock the key to treating muscle diseases and injuries.

Zebra fish share 70 per cent of their genes with humans, and are also transparent, making them perfect specimens for research.

"You can see right through them … you can see the stem cells dividing," Professor Peter Currie from Monash University said.

Muscle stem cells are the key to repairing tissue, but growing them in a lab so they can be used therapeutically has been difficult.

But now, researchers investigating the role of certain immune cells have found a naturally occurring protein that heals muscle.

"The most important phrase ever uttered in the lab is not 'Eureka, I found it', it's 'oh my God, that's bizarre, I've never seen that before'," Professor Currie said.

After fish, the protein was tested on mice with severe muscle damage.

It worked, with the muscle completely regenerating and movement returning to normal.

Clinical trials are the next step.

There are hopes it could help people of all ages, including repairing day-to-day muscle injuries, to helping the frail, and potentially treating diseases like muscular dystrophy.

"We're speaking within a two-year time-frame for the preliminary pre-clinical trial testing and if that works, we'll be looking to move into clinical trials," Professor Currie said.

A stolen car has ploughed through a COVID-19 check point in rural WA, only narrowly missing a dozen people including police.

The joy ride came to an end just moments later, after the Ford Falcon Collided with a road barrier.

Police said they'd been trying to stop the car three kilometres away but the alleged high-speeds reached forced them to back-off.

The accused driver Jasmine Rose Jones has been taken into custody and charged alongside the passenger, her 27-year-old uncle Terry John Windie.

Police allege the pair stole the car from a home in Northam about 5.30pm yesterday, stopping a Toodyay petrol station to fill up and taking off without paying.

Terry Windie today pleded guilty to stealing the car, the court hearing he was "drunk" and "wasn't thinking."

He was sentenced to eight months community service and ordered to pay half of damages to the car worth about $6500.

The-27-year-old is also facing court on a stealing charge from November, ordered to pay back the $55 for a stolen carton of beer, telling his lawyer he was thirsty and had no money.

Ms Jones was remanded in custody for legal advice and will appear in court next month, facing charges for stealing a car, driving without a licence and drink driving.

A Florida man and his cousin have stopped a potential snake plague, catching and killing a 136-kilogram pregnant python at their home near Tampa.

The Burmese python is believed to be the biggest ever caught in the Zolfo Springs area and when Aaron Brown first spotted it on the side of the road, he knew he needed help, so called his cousin William Wilkerson for help.

"Once we got him pulled out – it was like 'My god! What a snake," Mr Wilkerson told Fox13.

After the pair had hooked and shot the snake, they realised they didn't have a tape measure so got two young family members to lie head to toe next to it.

The huge snake was an impressive 4.8 metres long.

When the family called in local snake catcher Dustin Crum to collect and skin the python, they found out it was pregnant with around 100 eggs.

Mr Crum told Fox13 snake catchers were working hard in the Everglades trying to stop snakes from migrating further north.

"Hopefully this is a rogue snake and they haven't migrated this far north," Mr Crum said.

"These boys stopped an invasion by eliminating a big breeding snake like that."
