It's been 15 years since Kathleen Folbigg, Australia's worst female serial killer, was found guilty of killing her four babies over a 10-year period.
But interest in Folbigg's case is set to peak again, five years after her legal team started a petition to have the case reviewed.
The petition reportedly casts doubt on forensic evidence that formed a major part of the case against her and includes testimony from expert witnesses and medical professionals.
Folbigg is often referred to as "the most hated woman" in Australia by the nation's media after her lengthy trial revealed none of her babies made it to their second birthday.
Phone calls between Folbigg, now more than halfway through her 25-year sentence, and a friend are set to air on ABC with the convicted child killer expressing her frustration over the government's delay.
Speaking to Australian Story tonight, Folbigg said she's been clinging to hope for years, ever since her legal team commissioned the review into her trial and sent a petition to the NSW Attorney-General.
"We're just simply waiting for a decision. For three years now, we've been clinging to that little bit of hope," Folbigg told the program.
Folbigg's lengthy trial, where the jury eventually found her guilty of three counts of murder and one count of manslaughter, went for more than seven weeks.
Throughout it, the prosecution alleged Folbigg had smothered and killed all four of her babies.
Folbigg's foster sister testified for the prosecution and, after her husband discovered his wife's harrowing diary entries, he joined the prosecution's case too.
The diary entries would prove pivotal in convicting Folbigg of the deaths, which spanned from 1989 to 1999.
Among the most damning of her entries, Folbigg wrote "I am my father's daughter."
Folbigg was 18 months old when her father stabbed her mother to death in a Sydney street.
In the phone calls aired by Australian Story, Folbigg said the diary entries were "written from a point of me blaming myself."
"I blamed myself for everything. It's just I took so much of the responsibility, because that's, as mothers, what you do," she said.
NSW Attorney-General Mark Speakman said the petition "raises complex questions to which I am giving appropriate consideration and have taken extensive advice".
"I hope to be in a position to make an announcement in the near future," he said in a statement.
Within the petition to get a judicial review, Professor Stephen Cordner concludes that there was no forensic evidence to prove all four of Folbigg's children were murdered.
Prof Cordner, one of Australia's most distinguished forensic pathologists, cast doubt on the evidence used to convict Folbigg back in 2003.
After combing through all of the evidence presented at Folbigg's trial, Prof Cordner concluded Caleb and Sarah died from SIDS and Patrick, who had epilepsy before his death, most likely died from complications brought on by the disease.
The professor also concluded Laura, who lived the longest, died "unexceptionally from myocarditis".
"There is no positive forensic pathology support for the contention that any or all of these children have been killed," Prof Cordner concluded in his report.
Folbigg was originally sentenced to 40 years for the murder of her children Patrick, Sarah and Laura and for the manslaughter of Caleb between 1989 and 1999.
The sentence was reduced on appeal to a maximum of 30 years.
In another of Folbigg's damning diary entries, she wrote Laura had been a "fairly good-natured baby".
A separate passage read: "I feel like the worst mother on this Earth. Scared she'll leave me now like Sarah did. I knew I was short-tempered and cruel sometimes to her, and she left. With a bit of help."
Explaining the "bit of help" line, Folbigg was recorded over the phone, claiming she was referring to a "higher power".
"That quote, that was a reference to God or to some higher power or something going on that I didn't understand. I was thinking why was I not allowed to have the other three but now I've fallen pregnant again am I going to be allowed to keep this one?"
While Nicholas Cowdery, the NSW Director of Public Prosecutions at the time, still believes the jury got its 2003 verdict right, he did admit the delay with Folbigg's petition had taken too long.
"I think this is an inordinate delay in dealing with this matter," he said.
