William Tyrrell's foster mother has made explosive new claims about police involved in the homicide investigation of the missing toddler's disappearance.

Almost five years have passed since the three-year-old boy mysteriously vanished without a trace from a Kendall home on the New South Wales north coast in 2014.

New episodes of Ten News First podcast Where's William Tyrrell? will be released on Monday, where the boy's foster mother claims internal politics and in-fighting from NSW Police officers involved in the case has hampered the investigation.

'I'm really angry because police are playing with William,' his foster mum told Ten News First.

'William's investigation right now is not going, they're getting ready for the coroner's court.

The foster mother, who can't be named for legal reasons, also expressed fears for the future of the investigation into William's disappearance after lead detective Gary Jubelin was abruptly removed from the case earlier this year.

He resigned from the police force and was last month charged with illegally recording a conversation with a person of interest involved in the case.

The former detective has denied any wrongdoing and will fight the charges.

His resignation devastated the families of victims whose cases he worked on, including William's foster parents.

'The only people who are fighting for William is us and Gary,' the foster mother said.

'I want them to know and I want the public to know that we are never ever giving up on finding out what happened to William and the people who can do that are police and they're doing nothing. Nothing. It's disgusting.'

Her allegations come as The Australian launched its own podcast into the cold case called Nowhere Child.

The publication reported on Friday the new head of the investigation, Detective David Laidlaw had never worked on the case before he took over earlier this year.

It's also understood he also started the case from scratch due frosty tensions between former NSW Homicide commander Mick Willing, his successor Scott Cook and Detective Jubelin.

In an earlier 'Where's William Tyrrell?' podcast released earlier this month, William's foster mother claimed that on the first day of investigation police failed to quarantine the scene where William went missing.

'When I reflect back on that period there were easily 10, 20, 30, 40 people that walked all through the house, the grounds around it, and all around mum and dad's garden and grassy area,' she told the Ten News First podcast.

'There is no wonder the dogs didn't get any scent.'

The foster mother claimed that at a 'fundamental' level it should have been easy to cordon-off the house and surrounding area.

She said right before the boy disappeared, the foster mother heard him roar like a tiger, which was was part of a hide and seek game the pair played.

Though when she couldn't hear the roars, that's when the foster mother began to worry and walked around in circles looking for the toddler.



An inquest into the disappearance of the three-year-old boy was launched earlier this year, where the foster mother described in vivid detail how 'silent' it got in the backyard.

She stopped drinking her cup of tea, went to find William, couldn't, and began to panic.

'I couldn't hear a thing. It was silent. There was no wind. No birds. Nothing. Couldn't hear a thing.

Another podcast delving into the case of William Tyrrell's disappearance has been launched

'All I could think was why can't I hear him? Why can't I see the red (of his Spiderman suit)?

'I'm standing there and - why can't I see him? Why can't I hear him? It was silence.'

Throughout the inquest, further details into the events surrounding the disappearance of the missing toddler have emerged.

Coronial documents revealed William's birth mother was told her son 'had a black eye' from an accident just before her final contact visit with the toddler five years ago.

The biological mother could still see a 'faint bruise' near William's eye when she saw him for the final time for two hours at the Chipmunk Centre at Macquarie Centre on August 21, 2014.

There is no suggestion whatsoever that the black eye was the result of anything but a typical accident of a toddler. Both William's foster and biological parents have been ruled out as suspects in his disappearance.

William was 'happy sitting on my lap and giving me a cuddle' and was 'more affectionate than usual' during the visit, the birth mother said in her statement.

Throughout the investigation numerous persons of interest have been identified. Some were charged with unrelated crimes as detectives dug into their pasts, others were cleared entirely.

In 2015 it emerged a ring of pedophiles had been active in the area and were being investigated. Years later, that theory has not conclusively been ruled out.

Public fascination with the mystery deepened in 2017 when a court ordered William's unusual family situation could be revealed.

William and his younger sister were in foster care when he disappeared.

The revelation, as with every development in the case, played out across national news bulletins and frontpages while sending armchair conspiracy theorists into overdrive on social media.

The second tranche of hearings, beginning August 5, will be watched closely by detectives as people they've identified as worthy of suspicion take the stand.

The coroner's legal powers mean witnesses could be forced to explain their movements and what they know about William's disappearance - unlike conventional police interviews.
