'Crucial time': COVID-19 warning ahead of the festive season

Rising COVID-19 cases has prompted calls for people to get their booster shot as the festive season approaches.

Leading GP Dr Brad McKay told Weekend Today that although COVID-19 hospital admissions were lower than previous years, it was still important to keep up-to-date with your COVID-19 booster shot.

"There are so many people who haven't had their third vaccine, let alone their fourth and this is really a crucial time," he said.

"If you've got a bit of a window of opportunity if you're due for a vaccine. If it's been three months since your last vaccine or three months since you've had COVID, go out and get it.

"A lot of my patients haven't had a vaccine since a year ago. Their immunity will be waning."

Dr McKay warned COVID-19 cases would be rising in the coming months.

"We're not seeing that many more people are ending up in hospital compared to previous," he said.

"I think we're optimistic it is going to be a low wave, not as bad as what we've seen previously, but it's just still a reminder to go out there and get vaccinated."

It comes just days after New South Wales residents were warned the state was in the early stages of its next COVID-19 wave.

"We're starting to see an increase in COVID cases and changes in the variants circulating in New South Wales, which tells us that we're entering the next COVID wave," Chief Health Officer Dr Kerry Chant said.

"By looking at all the local information we have and what's happening overseas, we believe COVID cases will rise in the coming weeks."

Hackers posted one image on coach's Facebook page, banishing him instantly

You know there's something fishy going on when a respected martial arts coach suddenly posts child exploitation material on his Facebook page, then buys up big on Vietnamese ads for angler rods.

But Jihad Bekai, who runs the G-Force martial arts school in Melbourne, said convincing Facebook's owner Meta of that has been downright impossible.

Last month, Bekai fell victim to Facebook hackers. They used a common and well-known ploy, previously reported on by 9news.com.au, which involves posting child sexual abuse material on a user's personal Facebook page.

Jihad Bekai's Faaccount was hacked a month ago. While he initially thought it would be an easy fix, he has been hit with multiple dead ends.

This triggers an automated response from Facebook, banning the user for violating its "community standards".

While the user is busy dealing with the fallout and trying to retrieve access to Facebook, the hackers go after their real target – usually a credit card linked to a business page they run.

Over the course of a month, the hackers have run up more than 50 charges on Bekai's credit card for Facebook ads, totalling more than $1000.

Meanwhile, Bekai said he had been stuck in an infuriating feedback loop with Facebook, whose online customer service forms fail to register the absurdity of his situation.

Bekai's account was disabled almost immediately after hackers posted child exploitation material on his Facebook page.

"Facebook is not contactable but they are happy to charge the credit card linked to my disabled account," Bekai told 9news.com.au.

"Since when do I run Vietnamese advertisements about fishing rods?

"Also, if their artificial intelligence is so fantastic that it can detect child pornography, why can't it put two-and-two together and realise it would be unusual for me to be doing 10 years of videos on martial arts and suddenly decide child pornography is my thing – so much so that I want to display it online for everyone to see in a public post."

From the moment hackers uploaded child exploitation material on Bekai's Facebook page, his entire social media presence was banished in one swoop.

Bekai lost access to his martial arts school's Facebook page and Instagram account. He also runs a cafe and a Melbourne martial arts tournament. He longer has access to those social media accounts either.

"It's 15 years of work, just gone, all of it taken away," he said.

"My Facebook page often gets 10,000 interactions, so does my Instagram. I've got all these high-quality, professional videos of us doing martial arts demonstrations."

Bekai's martial arts school only advertises on social media. The Facebook page is one of the main ways new customers find out about his business. 

"The G-Force page is still there but it has no admin, so it's floating now like a ghost page," he said.

Hackers moved quickly to buy up Facebook ads using Jihad Bekai's credit card.

After going around in circles for weeks, Bekai said he finally managed to speak to an online support worker for Meta. But the IT support worker's responses to him, written in poor English, were even more baffling and infuriating, he said.

In one conversation, seen by 9news.com.au, an IT support worker told Bekai he is unable to get a refund on the credit card charges because it had been determined a family member or a friend was using his credit card to buy the advertisements.

In another message thread, an IT support worker calls Bekai by the wrong name, before telling him he won't be able to get his account back, but to "have a sweet night".

"This is where it started to get insane," Bekai said.

"I was almost on the verge of thinking that Facebook itself had been hacked from the replies." 

'They watch the damage in real time'

Bekai's case is similar to that of Queensland tradie Michael Meyrick, who found himself and his business besieged by hackers in August this year.

The hackers began buying up Facebook advertisements in Vietnamese for nose hair trimmers on Meyrick's account, before posting them on his business page.

9news.com.au has been inundated with similar complaints from small business owners about Facebook hackers.

Australia's small business ombudsman Bruce Billson said the damage social media hackers wreaked on small businesses could be devastating.

Bekai said he relies on Facebook to maintain a profile for his business and attract new customers.

"Some people have built their entire businesses on Facebook or Instagram and we understand that having someone else access and control their account is devastating for their business and their reputation," Billson said.

"They watch the damage to their business occur in real-time with no ability to stop it."

Over the past 12 months, the ombudsman has helped investigate 34 cases of small business owners having their Facebook or Instagram accounts hacked or disabled.

Billson said his office often worked with Meta to help small business owners regain access to their accounts.

"Our office cannot make findings, or compel Meta to give particular outcomes, but we work collaboratively to help people get back to business as soon as possible," Billson said.

The first step people should take is to follow Meta's processes for hacked accounts, Billson said. 

If this did not work, they could contact his office for assistance, he added.

"We focus on getting the information that Meta need to resolve the issue, put in front of a real person at Meta," he said. 

"We have a very good relationship with Meta and they are helpful and responsive in relation to the issues we raise with them."

Users should secure their accounts by following Meta's advice to turn on multi-factor authentication, pick secure strong passwords and activate login alerts, he said.

"We would also encourage people to keep copies of their account details and URLs in a safe place so if they are hacked they can provide the information without the need to access the platform."

But following those steps doesn't always protect users.

'Facebook let them in'

Bekai said what is most frustrating about falling victim to Facebook hackers is that he seemingly did everything right to safeguard his accounts.

"I'm very savvy with computers – I have two-factor authentication and use very secure, random passwords," he said. 

"I never thought there was any way my accounts would be compromised."

Bekai said the hackers appear to have infiltrated his accounts by somehow adding themselves as an admin on his Facebook Commerce account, which links personal and business pages, plus credit cards together in the one place.

Bekai has been running his business Facebook page for 15 years.

"The first notification I got was an email saying someone has been added to my Commerce account," he said.

Bekai initially ignored the email thinking it was spam, but then another came through saying a second person had been added to the account.

"What did I do wrong? I had two-factor authentication. How did they get in?" he asked.

"Normally, if I log in on a new device myself, I can't, it pops up with a notification on my phone.

"I got no notifications. Facebook let them in and now they're punishing me for child pornography. What about my reputation now?" 

Desperate for a resolution, Bekai said he had resorted to contacting a lawyer to draft a legal notice to Meta on his behalf.

Bekai said he had also made a report to the Australian Cyber Security Centre (ACSC) but was yet to receive a response.

"It's a disgrace," he said.

"How can Facebook be allowed to destroy people's livelihoods in Australia. Is there no consumer protection? Don't have to meet some guidelines of how they operate."

The ACSC is receiving reports of cybercrime in Australia once every seven minutes as instances continue to climb, a report released Friday found.

After 9news.com.au contacted Meta, a spokesperson said the company was investigating Bekai's case.

"We work hard to protect our community and keep them safe from hackers," a Meta spokesperson said. 

"We use a combination of automated systems and people to help review content flagged by our community. We are committed to continuing to invest in AI to improve accuracy and strengthen our review and appeal systems."

Diver's incredible reaction after nearly diving into sharks' mouth

A marine biologist who almost dived straight into the mouth of a tiger shark has said she was "overjoyed" with the encounter, revealing the pair grew up together.

The incredible footage, which has gone viral, captured the moments before Ocean Ramsey entered the water in Hawaii.

In the video, uploaded to social media Ramsey hovers over the side of the boat as the five-metre shark circles below, its fin breaking the surface. As she goes to leap the shark turns and tries to nip her fins.

Ramsey told Weekend Today she was unphased, as she has known the animal for nearly 20 years.

"I was actually overjoyed to see her, especially that particular individual shark," she said.

"We call her Queen Nikki and I have grown up with her, we were teenagers at the same time."

In the video, Ramsey was seen laughing off the close encounter and told Weekend Today that she went into the water just moments after.

"It was incredible to see," she said.

"We have had so many beautiful interactions with her over the years and sharks are so important.

"I was actually laughing and I went in the water right after that moment.

"We were really excited to see her and we got back in the water and we were just grateful she was there."

Her comments come just days after a study revealed it used tiger sharks to help map what's believed to be the world's largest seagrass system in Bahama Banks.

Residents boil drinking water as NSW floodwaters soar

Flooded residents in the New South Wales central west town of Forbes have been told to boil their drinking water as the Lachlan River reaches its peak.

The water is expected drain slowly, as the community and its surrounding villages take stock after the worst flood in more than 70 years.

In the past 24 hours, there had been more than 25 flood rescues by State Emergency Service (SES).

Floodwaters on the Lachlan River reached their peak in the New South Wales central west town of Forbes.

There are currently just under 97 warnings across New South Wales, including 21 emergency warnings.

NSW SES volunteer Alex Griffith said the Lachlan River in Forbes still remained a focus area for the service.

"We are seeing near record levels," he said. 

"We are asking the community to stay out of the floodwater and do not to drive through floodwater.

A young mum and her two daughters were among those assisted by volunteers.

The rescue proved to be an adventure of sorts for Aria and Arabella, who are now at their grandfather's home, who described the day as "fun".

The day proved to be a double ordeal for pregnant woman Mamata Pun Rana, who was rescued from floods after her waters broke.

She made it to Forbes Hospital, where she welcomed her boy Imaan into the world on Saturday afternoon.

"We got her safely to hospital and it was great to be able to help out," SES volunteer Ryan Jones said.

After helping others, SES volunteer Rebecca returned to find her own home flooded but in time to rescue her cat Benny.

She said the situation was "very overwhelming".

https://twitter.com/livgracecurran/status/1588670143798063104

Forbes residents were advised to boil their water until further notice due to the flooding.

"Water used for drinking or food preparation should be brought to a rolling boil to make it safe," the local council told residents.

"Kettles with automatic shut off switches can do this. Water should then be allowed to cool and stored in a clean container with a lid and refrigerated.

"Bottled water or cool boiled water should be used for drinking, washing uncooked food, making ice, cleaning teeth, gargling and pet's drinking water.

"Dishes should be washed in hot soapy water or in a dishwasher."

Transport remains an issue in the town, with nurses getting boats to the local hospital to start their shifts.

The army is on standby for the clean-up in Forbes, which is expected to take place in several days.

Residents and businesses are encouraged to register their damage online with the SES so the army can assist once floodwaters recede.

The Lachlan flooding is expected to move downstream towards Condobolin.

Meanwhile as water levels slowly drop around Wagga, the inland city's river has fresh fields to flood.

Authorities said the Murrumbidgee River's water was expected to head towards Narrandera, where a peak is expected tomorrow.

NSW residents can stay up to date with the latest emergency warnings at the SES website.

Victorian families exposed in cyberattack targeting school students

Thousands of Victorian families may have had their personal data exposed in yet another cyberattack.

Hackers targeted PNORS Technology Group which is used by several state government departments, including the Department of Education and Training, according to The Sunday Age.

Sources told the Age data from the Victorian school entrance health questionnaire was included in the information stolen.

READ MORE: Singer-rapper Aaron Carter dies in California at age 34

The health questionnaire included personal information including demographics, developmental and behavioural issues, and family alcohol or drug problems.

It was completed by families who start at all Victorian primary schools.

PNORS chief executive Paul Gallo said the extent of the data breach is still being investigated.

"However, overnight the criminals behind the cyberattack released to the company in a private communication a sample of what is believed to be stolen data," Gallo said.

"When we were informed about the cyberattack we immediately shut down and isolated all our internal systems and took further measures to secure our network and data, along with pausing all data processing."

The hack comes just days after a prominent real estate agency in Melbourne was targeted by a cyberattack, leading to clients' personal information being leaked.

Harcourts Melbourne City said information which was visible to the third-party included email addresses, legal names, phone numbers and copies of signatures and bank details.

Why you don't need to worry about the radiation in this fruit

The simple mention of the word "radiation" often evokes fear in people. For others, it's fun to think a little exposure to radiation could turn you into the next superhero, just like the Hulk.

But is it true basically everything around us is radioactive, even the food we eat?

You may have heard bananas are mildly radioactive, but what does that actually mean? And despite us not being superheroes, are human bodies also radioactive?

READ MORE: How trees reveal Earth's history of unexplained 'radiation storms'

What is radiation?

Radiation is energy that travels from one point to another, either as waves or particles. We are exposed to radiation from various natural and artificial sources every day.

Cosmic radiation from the Sun and outer space, radiation from rocks and soil, as well as radioactivity in the air we breathe and in our food and water, are all sources of natural radiation.

Bananas are a common example of a natural radiation source. They contain high levels of potassium, and a small amount of this is radioactive. But there's no need to give up your banana smoothie – the amount of radiation is extremely small, and far less than the natural "background radiation" we are exposed to every day.

Artificial sources of radiation include medical treatments and X-rays, mobile phones and power lines. There is a common misconception that artificial sources of radiation are more dangerous than naturally occurring radiation. However, this just isn't true.

There are no physical properties that make artificial radiation different or more damaging than natural radiation. The harmful effects are related to dose, and not where the exposure comes from.

What is the difference between radiation and radioactivity?

The words "radiation" and "radioactivity" are often used interchangeably. Although the two are related, they are not quite the same thing.

Radioactivity refers to an unstable atom undergoing radioactive decay. Energy is released in the form of radiation as the atom tries to reach stability, or become non-radioactive.

The radioactivity of a material describes the rate at which it decays, and the process(es) by which it decays. So radioactivity can be thought of as the process by which elements and materials try to become stable, and radiation as the energy released as a result of this process.

Ionising and non-ionising radiation

Depending on the level of energy, radiation can be classified into two types.

Ionising radiation has enough energy to remove an electron from an atom, which can change the chemical composition of a material. Examples of ionising radiation include X-rays and radon (a radioactive gas found in rocks and soil).

Non-ionising radiation has less energy but can still excite molecules and atoms, which causes them to vibrate faster. Common sources of non-ionising radiation include mobile phones, power lines, and ultraviolet rays (UV) from the Sun.

Is all radiation dangerous? Not really

Radiation is not always dangerous – it depends on the type, the strength, and how long you are exposed to it.

As a general rule, the higher the energy level of the radiation, the more likely it is to cause harm. For example, we know that overexposure to ionising radiation – say, from naturally occurring radon gas – can damage human tissues and DNA.

We also know that non-ionising radiation, such as the UV rays from the Sun, can be harmful if the person is exposed to sufficiently high intensity levels, causing adverse health effects such as burns, cancer, or blindness.

Importantly, because these dangers are well known and understood, they can be protected against. International and national expert bodies provide guidelines to ensure the safety and radiation protection of people and the environment.

If the fear of radiation from nuclear accidents is important in this debate, so too is the issue of safely disposing of radioactive waste,

For ionising radiation, this means keeping doses above the natural background radiation as low as reasonably achievable – for example, only using medical imaging on the part of the body required, keeping the dose low, and retaining copies of images to avoid repeat exams.

For non-ionising radiation, it means keeping exposure below safety limits. For example, telecommunications equipment uses radiofrequency non-ionising radiation and must operate within these safety limits.

Additionally, in the case of UV radiation from the Sun, we know to protect against exposure using sunscreen and clothing when levels reach 3 and above on the UV index.

Radiation in medicine

While there are clear risks involved when it comes to radiation exposure, it's also important to recognise the benefits. One common example of this is the use of radiation in modern medicine.

Medical imaging uses ionising radiation techniques, such as X-rays and CT scans, as well as non-ionising radiation techniques, such as ultrasound and magnetic resonance imaging (MRI).

An X-Ray showed the button battery had been lodged in Shaylah's throat for six months.

These types of medical imaging techniques allow doctors to see what's happening inside the body and often lead to earlier and less invasive diagnoses. Medical imaging can also help to rule out serious illness.

Radiation can also help treat certain conditions – it can kill cancerous tissue, shrink a tumour or even be used to reduce pain.

So are our bodies also radioactive? The answer is yes, like everything around us, we are also a little bit radioactive. But this is not something we need to be worried about.

Our bodies were built to handle small amounts of radiation – that's why there is no danger from the amounts we are exposed to in our normal daily lives. Just don't expect this radiation to turn you into a superhero any time soon, because that definitely is science fiction.

Hay fever warning as weather heats up across Australia

Hay fever sufferers have been warned to stay alert over the coming days as the weather begins to heat-up across Australia.

Pollen levels have been lifted from high to extreme in parts of Victoria, as the state reaches a top a top of 25 degrees today.

Temperatures will continue to climb over the coming days, with Tuesday reaching a top of 27 degrees.

The warm stretch will also be felt in Adelaide, as the city is set to reach its hottest days since last Summer.

Weatherzone says a slow-moving trough lying over western parts of the state, will make its path towards central and eastern SA dragging warm air from the tropics.

Temperatures are set too peak in the low 30s from Monday to about Wednesday, with Tuesday possibly reaching 32 degrees, being the warmest day since last summer.

While Sydney is set to reach a top of 24 degrees today and Brisbane a top of 25 degrees. 

Monitoring systems across Sydney have pollen levels at Moderate.
