Kathleen Folbigg has begun the first chapter of her new life as a free woman with hugs and smiles after being pardoned over the death of her four children and released from jail.
Folbigg, 55, was convicted of killing her three children Patrick, Sarah and Laura and the manslaughter of her firstborn, Caleb, between 1989 and 1999, when the kids were aged between 19 days and 19 months.
After new scientific evidence raised doubts over the guilty verdict, NSW Attorney General Michael Daley on Monday announced Folbigg had been pardoned and would be released immediately.

The convictions, which resulted in her being jailed for 20 years, have not been quashed as that can only be done through the Court of Criminal Appeal.
Hours after she walked free from her Grafton prison cell, Folbigg was locked in a warm embrace with lifelong friend Tracy Chapman on a farm in northern NSW.
"I am so elated it's not funny. I am nervous and I am everything," she told 9News amid the joyous reunion.
With a new future now stretching out in front of her, the newly freed woman couldn't say what would come next.
"I don't know. I need a drink of water. I don't know about anything else," she said.
An advocate for Folbigg since her conviction two decades ago, Chapman created a "sanctuary" on the farm in case her friend was pardoned, somewhere "peaceful, quiet, she's surrounded by animals".

Folbigg has always maintained her innocence, saying her children all died of natural causes. She was 20 years in to a minimum 25-year prison sentence.
Announcing the pardon, Daley said the 55-year-old had endured "a terrible ordeal" and there was the possibility she could sue the government if the convictions were quashed, a legal move which goes beyond a pardon.
"What is the difference between today and what has transpired in the past? New evidence has come to light," Daley said, alluding to genetic information which was presented as evidence in an inquiry into the death of the babies.
Former NSW chief justice Tom Bathurst KC, the head of the inquiry, is preparing a final report for the NSW governor. That report could be finished this month.
In a memorandum outlining his findings, which was sent to Daley on Friday, Bathurst stated he had reached "a firm view" that there was reasonable doubt as to the guilt of Folbigg for each of the offences for which she was originally tried.
Key points in the memorandum which led to the pardon decision included "the reasonable possibility" that three of the children died of natural causes, and that in the case of Sarah and Laura there was "a reasonable possibility a genetic mutation known as CALM2-G114R occasioned their deaths".
In the memorandum, Bathurst was "unable to accept… the proposition that Ms Folbigg was anything but a caring mother for her children".

Diary entry murder theories thrown out
Prosecutors in the 2003 trial argued Folbigg smothered her children during periods of frustration and asserted that some of her diary entries were admissions of guilt
She was sentenced to 40 years in prison for murder, with a non-parole period of 30 years, later reduced on appeal to 25 years, but the diary theory was today descredited.
The diary entries, the memorandum said, "were the writings of a grieving and possibly depressed mother, blaming herself for the death of each child, as distinct from admissions that she murdered or otherwise harmed them".
New genetic evidence cast doubt on Folbigg's guilt and paved the way for her pardon.
Folbigg and her two daughters were found to carry a rare genetic variant, CALM2-G114R, which can cause cardiac arrhythmia and sudden death.
The genetic variant was a "reasonably possible cause" of Sarah and Laura's deaths, according to cardiology and genetics experts.
The variant was not found in Caleb or Patrick.
Daley said he had spoken with Folbigg's ex-husband, Craig — who still believes his ex-wife murdered their children — to let him know in advance what was happening today.
Craig is a shattered man, and his views have not changed about what occurred with his four children," Craig's lawyer Danny Eid said.
Folbigg was released from Grafton prison on Monday morning.
Folbigg supporter Peter Yates said it was a "wonderful moment" for a "wonderful person, a wonderful mum", a moment fellow ally Helen Cummings said had taken "too long" to arrive.

Crucial phone call
Last Tuesday, inquiry head Bathurst had telephoned Daley and the pair spent some time talking about the report and the conclusions it was drawing.
Bathurst indicated he was making substantial progress on the draft, but he'd already "come to a firm view" about what the outcome of the report would be, Daley said.
"He asked me if I would find it useful, or if it would assist, for him to send me in advance of his report his preliminary findings," he said.
"I told him I would find it very useful indeed and that would assist us all greatly."
Daley read a memorandum, mailed on Friday, which contained "very clear" reasons to pardon Folbigg.

"As you would expect over the weekend, I sought the appropriate advice and weighed up the options available to me very carefully."
Daley concluded Folbigg should be released from custody as soon as possible.
At 9.30am, Daley met with the governor, and the pardon was agreed.
The Australian Academy of Science acted as an independent scientific advisor to the inquiry, the second to investigate the Folbigg case.
Academy chief Anna-Maria Arabia said she was "relieved" Folbigg has been pardoned.
Arabia urged the government to consider creating a criminal case review commission which could look at controversial convictions, with independent scientists.
The first inquiry, launched in 2018, found no reasonable doubt to Folbigg's convictions.
