The federal government has updated its travel advice for Hong Kong, warning Australians to exercise a high degree of caution when visiting or travelling through the region.

Authorities can request access to personal electronic devices and passwords from anyone in Hong Kong, even if you're only transiting through the airport.

As of last month, it is illegal to refuse to disclose your devices' passwords to the Hong Kong police under the city's broad National Security Law.

From April 30, it will also be illegal to import alternative smoking products like vapes or possess them in public places, such as the airport.

Hong Kong's security laws can be interpreted broadly and apply to activities outside Hong Kong, including social media posts, the Australian government's Smartraveller website notes in its updated warning.

"The maximum penalty under Hong Kong's national security laws is life imprisonment," the warning reads.

"Citizens of other countries, including Australia, have been arrested, convicted and imprisoned under Hong Kong's security laws."

Authorities in Hong Kong are able to detain a person without charge for up to 16 days and deny them access to a lawyer for up to 48 hours, Smartraveller says.

The warning comes as Australians are flocking to Hong Kong in record numbers. 

In 2025 alone, 469,000 Australians travelled to the destination – a massive 27 per cent surge from the previous year, according to the Hong Kong Tourism Board.

The board attributed this surge to several key factors, including the launch of more direct flights, drawcard events and the city's stopover appeal.

A "cruel and manipulative" mother who faked her six-year-old son's cancer to secure thousands in donations has been jailed.

In South Australia's District Court today, Judge Geraldine Davison said she refused to accept that gambling and financial difficulties were the root cause of Michelle Bodzsar's offending.

The West Lakes mother, 45, had pleaded guilty to one count of engaging in acts likely to cause harm to her young son and 10 counts of deception.

She has been in custody since her arrest in December 2024 after being accused of forcing her distressed son to take pseudo medicine while falsely portraying that he had cancer, securing thousands in donations from the community.

"You attribute much of the root cause of this offending to financial difficulties, saying that you felt you were living beyond your means and needed to provide for your family with the latest fashions," Judge Davison said.

"I do not accept that … your offending is far more cruel and manipulative … It was designed as an attention-seeking device."

Her son had sustained an eye injury in a trampoline fall in September 2024 and tests by an ophthalmologist had cleared him.

But she told her husband, Ben Miller, that their son had cancer, and scans had revealed three tumours on his optic nerve, requiring eight rounds of treatment in the form of radiotherapy.

She uploaded social media posts with pictures showing her son with a shaved head, requesting donations to her son's bank account.

Bodzsar had transferred more than $5000 to her account for daily living and also received thousands in cash donations.

The harm caused to her son was perpetrated on a daily basis by giving him pseudo medication and forcing him to take it "even when he clearly did not want to", the judge said.

"It is a form of child maltreatment and child abuse."

The local school community also experienced shock, betrayal, anger, and a profound sense of shame and embarrassment, the court heard.

"They feel shame for being naive and embarrassed for not spotting the lies earlier," the judge said.

Outside court, Miller said that "no sentence will ever justify what was done to my children".

He was initially arrested but had "absolutely no idea what was going on", the judge said.

"Your crimes have resulted in him losing his job, his career, and being unable to get work because he was on home detention, and no contact with his children for almost seven months," she said to Bodzsar .

Their son was now "angry and sad for no apparent reason" and their daughter was anxious about being abandoned and has been deeply affected, the judge said.

Bodzsar was given a head sentence of four years, three months and 20 days, with a non-parole period of two years and four months, meaning she will be eligible for parole in a year.

Two people have died and another is fighting for their life after a light plane crashed into an aircraft hangar just north of Adelaide.

South Australia Police chief inspector Andrew McCracken said the DA42 four-seat twin-engine aircraft took off from Parafield Airport after 2pm today and crashed into the Hangar 54 shortly after take-off.

The plane burst into flames and sent thick black smoke into the air.

A pilot and their passenger died in the crash and a number of airport staff who were inside the hangar at the time were injured.

One person was taken to the Royal Adelaide Hospital in a life-threatening condition with significant burns to their body.

Two others were taken to the same hospital in a serious condition and another with minor physical injuries.

Four people were taken to Lyell McEwin Hospital for treatment for smoke inhalation and a further two were taken to Modbury Hospital.

The Air Traffic Safety Board will visit the airport tomorrow morning to assist with the investigation.

"A pathologist is on scene, along with major crash staff," McCracken said.

"It is subject to a full investigation and a cordon will remain in place overnight for at least 24 hours as the matter is investigated."

A Metropolitian Fire Service (MFS) spokesperson said almost 60 firefighters were called to the scene and brought the blaze under control in 20 minutes.

The fire significantly damaged the hangar and several planes inside.

The crash also impacted the fire hydrant system at the airport, which left the sprinkler system out of action.

The MFS issued a smoke advice for the Parafield and Mawson Lakes area due to the extent of the smoke.

Parafield is located about 15 to 18 kilometres north of the Adelaide CBD.

It is the second light plane crash in Parafield in a matter of months.

In January, a plane crashed at Parafield Airport as it was about to land.

The pilot and sole occupant walked away from the crash uninjured.

The plane caught fire on impact and flames spread to nearby grass.
