I haven't followed this case closely but I always assumed the kids hadn't been there before because they hadn't been in foster care or with those foster parents for long. I don't know if that's right or not tho.
WILLIAM TYRRELL’S FOSTER HOME INTENDED TO BE PERMANENT

WHEN an eight-month-old William Tyrrell arrived at the home of his new foster parents, it was an arrangement that was always intended to be permanent.
The baby boy had been removed from his biological parents — both of whom had encountered problems with police —
and placed in the care of foster parents.
His biological father was a career criminal who had spent most of William’s short life incarcerated.
It is understood his biological father and mother, Karlie, whose name was released this week after a ruling in the NSW Supreme Court, have been linked to domestic violence-related incidents.
However, these occurred after William had been removed from their care and there is no suggestion either were ever violent towards him.
'
It is understood William’s foster agreement with his new parents in Sydney’s northern suburbs was intended to be a permanent arrangement.
His biological mother was aware of the intention.
Before his disappearance in September 2014,
William did have supervised visits with his mother, contrary to some media reports.
However
it’s understood these visits were infrequent and that
William identified his foster family as his parents and was known to the public by their surname (which can’t be disclosed)
and not "Tyrrell".'

'William's in-care status was only made public last month after the NSW Department of Family and Community Services lost a legal bid to stop an advocacy group using the information in pushes for a coronial inquest.
Senior police insist the investigation is "very much ongoing" and a $1 million reward for information leading to his return remains on offer.
Detective Chief Inspector Gary Jubelin, who leads the homicide investigation, will speak publicly about the case on Tuesday after last month reiterating his defence of
the foster family, saying they'd
provided "a loving home" for William.
The identity of William's biological parents, Karlie Tyrrell and Brendan Collins, was revealed only after the recent case - where the Court of Appeal upheld a Supreme Court ruling citing public interest and the need for scrutiny of the out-of-home care system in allowing more to be publicly known.
Those court documents paint a picture of the
life of a boy who was given a fresh start after being removed from the care of his biological mother as a seven-month-old.
There were concerns about domestic violence and drug use in the home and
William, the second-eldest of four children, was placed with a Sydney family.
He was reunited with his older sister a week later and the pair settled into their new family after the Children's Court found there was no "realistic" possibility of them returning to their birth mother.'
