In short:
Perry Kouroumblis, 65, is set to be interviewed by police over the suspected double-murder of Suzanne Armstrong and Susan Bartlett, who were found dead in 1977.
A family member of Ms Armstrong says it is a "surreal feeling" to know the extradition has been completed.
What's next?
Victoria Police will charge Mr Kouroumblis with two counts of murder and one count of rape when he faces court.
The prime suspect in the 1977 Easey Street double-murder investigation, Perry Kouroumblis, will be charged with murder and rape after his extradition to Australia was completed on Tuesday night.
Under police guard, Mr Kouroumblis touched down at Melbourne Airport late after flying from Italy, via Qatar.
Victoria Police said he was set to face court later on Monday, after being interviewed and charged over the alleged murders of Suzanne Armstrong and Susan Bartlett.
"Over the past four decades, a significant and tireless investigation into the murders has been conducted by detectives from the Homicide Squad," police said in a statement.

Ms Armstrong and Ms Bartlett were found dead in their Collingwood share house in January 1977, in what Victoria Police Chief Commissioner Shane Patton described as "an absolutely gruesome, horrific, frenzied homicide".

Ms Armstrong's niece, Wendi Selkrig, said it was "a surreal feeling" for the family to know that the extradition had been completed.
"I think that just knowing that this seems to be a promising lead is comforting as well," she told the ABC.
"I don't think we've ever given up hope, because the police have been fantastic the entire time. They certainly have never forgotten the case."
Ms Selkrig said the biggest question her family wanted answered was why two young women in the prime of their lives were killed.
"It's devastating to so many families, including the suspect," she said.
"Whoever's done this, they've lived with this in the back of their mind their whole life."
Ms Armstrong, 27, and Ms Bartlett, 28, were high school friends living together in the Easey Street property. Police allege the pair were stabbed multiple times, and Ms Armstrong was sexually assaulted.
Ms Armstrong's then-16-month-old son Gregory was left unharmed in a cot and was found days later.

"Suzanne was a mum to a really little baby at the time. She was a brilliant person. Susan was a school teacher. They both came from really good families," Ms Selkrig said.
"As more and more time goes by, it's forgotten that they were real people."
Mr Kouroumblis, 65, is an Australian-Greek dual national who had been living in Greece since 2016.
He was detained in Italy on an Interpol Red Notice in September, after arriving on a flight from Greece.
"He had no idea he could be stopped and was surprised to be stopped for something that went back to 1977 in Australia. So he did not give any resistance. He did exactly what the police told him," his lawyer Serena Tucci previously said.
Ms Selkrig acknowledged Mr Kouroumblis was innocent until proven guilty, and said she was encouraged by the fact that he had cooperated with police since his arrest.
Potential trial could be years away
In September, Mr Patton described the killings as Victoria's "most serious cold case and longest cold case".
In 2017, police announced a $1 million reward and said they had looked into about 130 potential suspects.
If Mr Kouroumblis is charged, it is likely he will be taken to the Melbourne Magistrates' Court for a filing hearing on Wednesday or Thursday.
Typically, a magistrate hears basic details about the charges during a filing hearing. Police provide the court with a timeline of how long it will take to compile their brief of evidence and make it available to the defence legal team.

An accused person is not required to enter a plea of guilty or not guilty during a filing hearing.
Mr Kouroumblis will be detained in custody if he is charged with murder, and will only be able to apply for bail if his lawyers front the Supreme Court in a separate hearing.
Any potential trial before a jury of 12 ordinary Victorians could be years away.
Prosecutors will first need to convince a magistrate that there is sufficient evidence for the case to proceed to a Supreme Court trial, at a hearing called a committal.
An accused person is required to formally state how they wish to plead to the charges at the end of the committal process.
If a person is committed to stand trial, months of administrative and legal argument hearings generally occur in the Supreme Court before the case is put in front of a jury.
