A woman who was drugged and assaulted by evil child killer Michael Guider has continued to plead with the government before the paedophile is freed from jail, amid fears he could offend again. 

Daily Mail Australia first revealed Michael Anthony Guider, 69, will be freed from the Metropolitan Special Programs Centre at Long Bay on June 6 unless the New South Wales government wins a court action to keep him inside.

Guider was serving a 16-year sentence imposed in 1996 for 60 offences against 11 children when police realised he was also responsible for one of Australia's most high-profile unsolved crimes - the death of nine-year-old Samantha Knight.

The schoolgirl disappeared from her mother's home in Sydney's eastern suburbs in 1986, leading to one of the largest searches in Australian history. 

Another of Guider's victims, Chantelle Hamilton, 30, is continuing to fight against his impending release and is protesting to get the laws changed.

Ms Hamilton told Daily Mail Australia she started her campaign a few years ago to keep Guider locked up but has since expanded her movement to keep paedophiles as a whole in jail.

'The last couple of years having to stress and worry and fight to keep Guider in jail, it completely consumed my life for a few months every year and it's very hard to get past, especially being a victim,' she said.

'Which is why I changed my attention to actually getting the laws changed.' 

When asked how much of a threat Guider would be, Ms Hamilton explained the convicted paedophile would be able to put on an act. 

'He's not a stupid man, he's quite charming and he is intelligent,' she said.

'He doesn't look the way they've made him look in the press. 

'He didn't look like that then and he won't look like that when he gets out.

'He'll be clean-shaven. That's what makes him such a threat.'

Ms Hamilton said he was 'absolutely' capable of offending again, referring to his ability to gain the trust of unsuspecting parents.  

'You wouldn't leave your kids with someone who looked the way Guider's perceived to look,' she said.

'That's why he's so scary. He looks like the type of guy you would leave your kids with and that's what makes him so dangerous.'

Ms Hamilton is fighting the government to introduce 'Knight's Law' where convicted killers will not be eligible for parole without providing the location of a body. 

'If you kill a child and you don't provide a body, which is what Guider's done, you don't get released,' she explained. 

'The fact that he's never provided a body, that he's never publicly said sorry to any of us shows he's not remorseful.

'He kept images, you know, that is not remorseful. That is wanting to look over the pain you caused over and over.'

Ms Hamilton will take her campaign for Knight's Law to Jetty Road, a main street in Adelaide, on Sunday where hundreds of protesters will gather for changes to the law. 

'I just felt nothing I was doing was being taken seriously by the government. So I thought I might do a march so they can't ignore us,' she said.   

'We are marching for no second chances (for paedophiles) and for the government to protect our kids and put kids first instead of protecting the rights of paedophiles over their victims.

'I'm angry now and I'm stubborn and I want things to change. I've got kids now so I think that pushed me, I just want things to be safer for the kids.' 

Ms Hamilton also has created a change.org petition to keep Guider in jail.

The petition already has over 100,000 signatures which she describes as 'amazing'.

Guider (pictured) preyed upon single mothers, offering to babysit with the intent of abusing their children 

Ms Hamilton was six-years-old when she first met Guider, a self-taught expert in Aboriginal rock art who also worked as a gardener, 60 Minutes reported.

Guider preyed upon single mothers, offering to babysit with the intent of abusing their children. 

He would then drug, sexually abuse and photograph the children he was supposed to be looking after.

Ms Hamilton said Guider's mood changed the second her mother left her and a friend at their home in Manly on Sydney's northern beaches.

'That's when dirty magazines were on the coffee table all of a sudden. He was setting the mood,' she said.

'He... would just get us naked and... he'd get us to touch each other and stuff.'

Police searched Guider's home and found thousands of photos showing the abuse of nine girls and two boys.  

Guider was arrested and charged with Samantha's murder in February 2001, but pleaded guilty to manslaughter under the weight of damning evidence including a confession to his brother Tim, a jailed armed robber.

The NSW Attorney-General, Mark Speakman, has moved to stop Guider's release by launching court action that would keep the serial child sex offender behind bars for another year.

Mr Speakman filed an application in the Supreme Court seeking a 12-month continuing detention order against Guider, as well as an additional five-year extended supervision order.

That second order would have 'stringent conditions controlling where the offender lives, where he can go and who he can associate with,' Mr Speakman told Daily Mail Australia.

Those conditions were likely to include electronic monitoring.

'NSW has the toughest post-sentence detention and supervision laws in the country which make community safety the priority,' Mr Speakman said.

'Any further comment from me while this matter is before the court would be inappropriate.'

Guider does not need to apply for parole because his maximum sentence expires on June 6.

Guider played a 'game' called statues with some victims, during which he ordered them to stand still while he exposed himself and touched their genitals; he took thousands of images of the children he violated while they were drugged.

The long-haired gardener claimed some of the mothers knew what he was doing and told a psychologist at least one of them - not Sam's or Chantelle's mother - did not mind.

'She was bad,' Guider said of the mother. 

This is the block of flats in Imperial Avenue, Bondi, where Sam Knight lived with her mother Tess in 1986 

'I was screwing her two kids and she asked me to do it to her after I'd been doing it to them.'

Guider first molested Sam when she was living with her mother Tess at Manly in 1984 and 1985.

He snatched Sam from near her home in Imperial Avenue, Bondi, after school on August 19, 1986.

The honey-blonde, green-eyed girl had been seen that afternoon walking the streets in her uniform. Within days, Sydney was plastered with 'Find our Sam' posters describing the young girl as intelligent, outgoing and well-spoken.

Guider later claimed he had drugged Sam with the sleeping pill Normison and she died of an overdose on his lounge while he went out to the shops.

He told investigators he buried Sam in Cooper Park at nearby Bellevue Hill, but dug up her body 18 months later when he saw workmen near her grave.

Guider said he then put Sam's remains in a dumpster containing landfill at the Royal Sydney Yacht Squadron at Kirribilli on the other side of the harbour.

After Guider pleaded guilty to manslaughter, Sam's mother said: 'Guider is the only person who knows where Sam is.'

'There is no reason why he can't tell us where Sam is. I think I would like to know a little bit more about what happened.'

Sam's father, Peter O'Meagher, whose marriage to Tess had been short, said: 'We've got to bury her. We really just want that.'

Guider was sentenced in August 2002 to 17 years' prison with a non-parole period of 12 years for manslaughter.

He first became eligible for release in June 2014 when the State Parole Authority refused to let him out and determined he could seek freedom the following year.

Parole was again refused in 2015, at which time the authority decided it would not consider his release again until 2017. Guider did not seek parole in 2017 or 2018.

Guider's case was mentioned in the Supreme Court on Tuesday and returns to court in May. Samantha Terese Knight would be 41 if still alive.
