Melbourne to exit lockdown on Thursday evening, with a 25km travel limit.

Barring any new mystery COVID-19 vases, Melbourne's extended "circuit breaker" is set to end at 11:59pm on Thursday and be replaced with restrictions similar to those currently in regional Victoria. 

That would involve a continued ban on private gatherings, venue density limits and mandatory indoor masks in most settings. 

The 10km limit on travel from home is likely to be extended to 25km after Acting Premier James Merlino flagged Melbourne residents will be unable to enter regional Victoria over the Queen's Birthday long weekend.

Victoria had two new cases on Tuesday and they are linked to existing infections. A final decision on eased restrictions for Melbourne and regional Victoria is expected to be finalised Wednesday morning.

Authorities are investigating a link between an outbreak of the more infectious Delta strain and a hotel quarantine case, a man in his 40s, who returned from Sri Lanka on May 8. 

Genomic sequencing shows his infection is identical to one of the two families linked to the North Melbourne Primary School, which has emerged as the epicentre of the West Melbourne outbreak. How the virus spread between the two groups remains a mystery. 

Perth vigil for detained Biloela girl as NZ and US flagged for resettlement. 

Supporters of a Biloela family detained on Christmas Island will hold a candelight vigil outside Perth Children's Hospital, where the youngest daughter is battling a blood infection.

Three-year-old Tharnicaa is being treated at Perth Children's Hospital after being evacuated from the island with her mother Priya Murugappan.

Her potentially-deadly blood infection has been linked by supporters to untreated pneumonia.

Priya says her daughter was sick for almost two weeks and that medical contractors at the immigration detention centre repeatedly refused to take her to hospital.

"I want to thank everybody for their love and good wishes," Priya said in a video message as she cradled her daughter.

"I hope that Tharnicaa can get the help she needs now. Please, help us to get her out of detention and home to Biloela."

Candelight vigils will be held outside the hospital on Wednesday evening and at Sydney Town Hall on Thursday.

Family supporter Angela Fredericks said medical arrangements for detainees on Christmas Island, far off the coast of WA, were inadequate and dangerous.

Priya, her husband Nades and their Australian-born daughters Tharnicaa and Kopika, 6, have been in detention since 2018, and on Christmas Island since August 2019.

Home Affairs Minister Karen Andrews said on Tuesday, "a range of resettlement options" were under negotiation for detainees, while Foreign Minister Marise Payne told 2GB, "I understand that there are two options that are being looked at. I understand the United States is the first of those and that New Zealand is also an option."

The family's lawyers say they have not been informed of either option.

The government has previously vowed to never permanently resettle anyone who arrives illegally by boat.

A petition to bring the family home to Queensland gained more than 100,000 signatures overnight, and now sits at more than 400,000. 

UK policeman admits Sarah Everard's rape, kidnap.

A police officer has admitted the rape and kidnap of Sarah Everard, whose killing sparked anger and soul-searching across Britain about what police, government and society can do to stop male violence against women, the BBC reports.

Wayne Couzens, 48, a London officer who guarded diplomatic premises, also accepted responsibility for killing Everard but did not enter a plea while medical reports were being prepared, the BBC said on Tuesday.

Everard, 33, was abducted as she walked home from a friend's house in south London on March 3. Her body was later found in woodland about 80 kilometres away in southeast England.

An autopsy concluded earlier this month she had died as a result of compression of the neck.

Couzens had been due to enter a plea next month but at a hearing at London's Old Bailey Court he pleaded guilty to both the rape and kidnap charges, media said.

Everard's murder provoked outpourings of anger from women who have recounted their own experiences and fears of walking the streets on their own at night.

Two reality stars arrested in organised crime sting.

A global sting in which organised crime gangs were sold encrypted phones that law enforcement officials could monitor has led to more than 800 arrests and the confiscation of drugs, weapons, cash and luxury cars, officials say.

The operation by the US Federal Bureau of Investigation, Australian and European police ensnared suspects in Australia, Asia, Europe, South America and the Middle East involved in the global narcotics trade, the officials said.

Millions of dollars in cash were seized in raids around the world, along with 30 tonnes of drugs including more than eight tonnes of cocaine.

Australian police said they had arrested 224 people, including members of outlawed motorcycle gangs, and disrupted 21 murder plots.

Sopiea Kong, 33, who starred in the 2017 season of Ninja Warrior was charged last week after police allegedly seized 154g of meth. Samuel Minkin, who appeared on Becky and Elly Miles’ season of The Bachelorette, was charged with possessing a large commercial quantity of cannabis.

Australian Prime Minister Scott Morrison said the operation had "struck a heavy blow against organised crime – not just in this country, but ... around the world".

Operation Greenlight/Trojan Shield, conceived by Australian police and the FBI in 2018, was one of the biggest infiltrations and takeovers of a specialised encrypted network.
