Also explains why he chopped off his own finger with a plastic knife

Milat writes about his hunger strikes and why he'll never plead guilty

He believes his uncle may not have

Shipsey has used 94 of Milat's letters in a new book about the killer

He writes up to twice a week to his eldest nephew, Alistair Shipsey

The rambling letters of Australia’s worst serial killer, who is serving seven consecutive life sentences for the brutal murder of seven backpackers, have been revealed in a new book.

Ivan Milat, 70, who was convicted of butchering seven young people between 1989 and 1992 and burying their bodies in the Belanglo State Forest in southern NSW, has been locked up in Goulburn Supermax jail for almost 20 years.

During that time he began writing up to twice a week to his eldest nephew, Alistair Shipsey.

Shipsey, a 55-year-old former Rebels bikie gang member, has compiled Milat's letters - including a note reasoning why the twisted killer chopped off his own finger in jail - into a $32 book titled The Milat Letters, which he promises ‘you won’t be able to put it down’.

The book's blurb reads: ‘Innocent or guilty? This book contains 94 letters from Ivan Milat who is currently serving seven life sentences for the murders of seven backpackers.

Ivan Milat butchered and buried the bodies of seven young people between 1989 and 1992 in the Bengalo State Forest in southern NSW

His eldest nephew, Alistair Shipsey, has written a book from the letters Milat has sent him since being locked up

‘They say he had someone or others with him – but we will never know. He still denies his guilt in the brutal murders that were carried out in the Belanglo forest between 1989 and 1992. He has been inside for twenty years now.’

An extract from one of the letters from Milat, written before he chopped his own finger off with a plastic knife in January 2009, affectionately refers to Shipsey as 'Al'.

It reads: 'No AL, I will never give up, say I did it or anything, I certainly don't give a f**k about car services letting me out of HRMU.

'I do battle to cope with this sh***y claustrophobic place, no windows, it's like a cement coffin. I suffer badly at times, I think the walls close in, no air, it's a real sh*t feeling, no I will never plead with the p***s.

‘I will send them parts of my hand first, I have been considering this for a while and only need half a reason to show them how I feel with their sh**head ideas, there is not much they can do to me any more and at my age I don't give a f**k.'

Milat, a former road worker, and his brothers had a large collections of knives and firearms when police searched their home

The serial killer lost his little finger on his left hand after he severed it in an attempt to send it in a padded envelope to the High Court. Goulburn Base Hospital was unable to reattach the finger.

Another letter sent by Milat to Mr Shipsey talks about the hunger strike he decided to go on after he butchered his own finger.

'For seven days after I chopped my finger off, I was locked away in a safe cell, light on 20 hours a day, no idea of time, it’s in a cement box, no windows or openings.

‘The best way I deal with that sh*t is don't eat, and after a couple of days I had all that pain in my hand, so after a couple of days I didn't give a f**k what happened, it took seven days to negotiate as usual once I agreed to start eating.'

On a Facebook page used to advertise the book, Shipsey makes his thoughts around his uncle’s imprisonment clear and blames the media for not reporting the real facts.

‘These letters are legit, written by Ivan himself, it’s been written for those who want to read it, it’s one of a kind, you can read the way he lives in supermax in his cement coffin,’ Mr Shipsey wrote.

He promised no money from the book’s sale will go to Milat because ‘he doesn’t need it where he is.’

‘I have put the letters together to let anyone see he’s in hell where you want to see him, so it’s interesting to see his comments on his struggles fighting for his appeal, everyone is entitled to justice, something he is being denied.

‘Remember, the media can say what they want, and people believe it without looking into the real fact [sic],’ Shipsey wrote.

British backpacker Caroline Clarke had been shot 10 times in the head when police found her body

Daily Mail Australia has contacted Shipsey for comment.

The first two bodies of Milat’s victims were discovered on September 19 and 20 1992, when two runners found a decaying corpse in the Belanglo State Forest.

Police later confirmed the bodies were of missing British backpackers Caroline Clarke and Joanne Walters. Walters had been stabbed 35 times and Clarke had been shot 10 times in the head.

The grim finds were just the beginning of a long and extensive search which resulted in the bodies of Australians Deborah Everist and James Gibson being found in October 1993, followed by Simone Schmidl’s stabbed body in November of the same year.

The decapitated body of German backpacker Anja Habschied was then found along with her boyfriend Gabor Neugebauer on 3 November 1993 in shallow graves 50 metres apart.

First victims: Australians James Gibson and Deborah Everist, both aged 19, were Ivan Milat's first known victims after they disappeared in December 1989 and their bodies were found in the Belanglo State forest almost four years later

Milat was convicted of the seven backpacker murders on July 27, 1996 and for the attempted murder, false imprisonment and robbery of Paul Onions.

He received seven life sentences and is now incarcerated in Australia's toughest prison, the High Risk Management Correctional Centre, known as Supermax, in the city of Goulburn south of Sydney and near the Belanglo forest.

He kept the shirts, sleeping bags, a water bottle, portable stove and backpacks of his victims hidden in roof and wall cavities, in what was described as an 'Aladdin's Cave', in the house he was arrested in 20 years ago.

Pictures of the 'trophies' which forensic investigator Rod Milton said gave the serial killer pleasure and which he kept or gave to family members and his girlfriend were revealed in a book in 2014.

Called 'Milat', the book was written by Clive Small, the detective who led the task force investigating the murders of the two young Australians, three Germans and two British girls whose bodies were found murdered and buried in ritual gravesites.

Simone Schmidl's body was found in November 1993. She had been stabbed to death

Mr Small described his book as 'a story of unfathomable cruelty, a portrait in terror . . . but also a story of the kindess of strangers in friendships forged when the families of the victims met under terrible circumstances'.

The pictures include those of the tent and sleeping bag cover which belonged to Simone Schmidl, 20, who Milat stabbed to death in 1991. Wrapped around the tent was a 'compact-o-mat' headband, identical to the band around Schmidl's skull at the forest burial site.

The book also details items including the German brand portable stove and other mountain sports equipment Milat souvenired after killing Ms Schmidl.

The book also contains details of the insulating tape, sash cords and cable ties including improvised leashes Milat used to bind and subdue the backpackers.

The Next brand blue denim shirt belonging to Briton Paul Onions which was found in a box in the garage of the home of the serial killer's mother, Margaret Milat. Ivan Milat himself wore the shirt which he souvenired after abducting Onions on the highway in western Sydney where he picked up all his victims, Onions being the only one to escape by leaping out of Milat's car at gunpoint

Mr Small said lengths of sash cord found in a pillow case belonging to Ivan Milat's mother, Margaret, were likely the same sash cord used as a 'leash device' in the murder of German former soldier, Gabor Neugebauer, 21, who was gagged and shot six times and his 20-year-old girlfriend, Anja Habschied, who was decapitated and her spinal cord severed.

Then Detective Superintendent Small led the seven month investigation into the murders which culminated in Milat's arrest on the morning of May 22, 1994.

The arrest, which led police to uncover more than 300 items including victim's belongings, firearms and at houses of Milat, his brothers and his mother, took place in the early morning after police negotiator, Wayne Gordon, managed to coax Milat - a controlling psychopath - out of the house.

Mr Small said 'teams of police dressed in black, with bulletproof vests and armed with shotguns and submachine guns' had surrounded the property while it was still dark.

At 6.36am, Detective Chief Superintendent Wayne Gordon, then a sergeant and lead negotiator in the State Protection Group, called Ivan's number.

Gordon told the Mailonline he had been coached by forensic psychologist Dr Rod Milton into how to deal with with a control freak.

'I was given a rundown on the mindset of a person with a dominant, controlling personality suspected of violence and murder,' he said.

'He'd been under surveillance for some time. We knew he'd gone to sleep inside the house, that he had firearms.'

Australia's worst serial killer Ivan Milat kept trophies to remind him of each murder

Police found hundreds of items in serial killer Ivan Milat's Eagle Vale home in western Sydney, including this blue Salewa brand sleeping bag cover wrapped around the Vaude Hogan brand tent with pegs and cords. Both items belonged to Simone Schmidl, 20, who Milat stabbed to death in 1990

Detective Gordon said the plan was to convince Milat to come out alive and without incident.

As Clive Small records in his book, when Gordon first asked, 'Mr Ivan Milat, is it?', a male voice answered, 'no, he's not here at the moment', but Gordon knew it was Milat's voice.

Gordon identified himself as a negotiator with the State Protection Group, and told Milat, 'I want you to come outside for the safety of yourself and whoever's in the house with you. Now what I want you to do is to come out the front door. I want you to turn left, go through the front gate. I want you to walk with your arms out, exposed from your body ...

'You'll be met by some State Protection Group police who'll be dressed in black. They will be armed and I want you then to lie face down on the ground.'

Gordon says he recalls Milat was 'very alert and challenging on the phone. It took two phone calls over about 30 minutes. I told him armed police were all around the property.

The Indonesian Rupiah banknotes forensic investigators found among Australian cash on the bedside table of the bedroom in Ivan's house police believe belonged to German former soldier, Gabor Neugebauer, 21, who was gagged and shot six times and his 20-year-old girlfriend, Anja Habschied, who was decapitated, put on a leash made from a sash cord perhaps from Milat's mother's house and her spinal cord severed. The young couple had been on holiday in Indonesia before arriving in Australia

Hidden horrors: In roof and wall cavities (above) of serial killer Ivan Milat's home in western Sydney police uncovered hundreds of items related to his murders of seven backpackers, including clothing and camping gear belonging to the victims and knives, firearms and round of ammunition which the gun-obsessed control freak had in his personal collection

'He was confident and cocky. He wanted to be in charge, or he attempted to be. I think he was trying to hide things in the cavities of the walls of his house during that time.'

Eventually, Milat agreed to come out once he 'put me pants on'.

On the second phone call, Small recalls, 'Ivan sounded calm and told Gordon he thought it was "someone from work" ringing up for a joke. Gordon assured Ivan that it was no joke.

'Ivan laughed and told Gordon he had looked out of the window but couldn't see any police. While Gordon repeated his instructions, Ivan went on laughing and ignoring the instructions.'

Eventually, Milat emerged with his girlfriend, Chalinder Hughes, and the pair stood on the lawn as Milat was handcuffed ready for the walk through of the house.

Clive Small remembers he seemed unfazed by the fact he had been charged with the abduction of Briton Paul Onions - the seven backpacker murder charges would not be laid until after police had gathered evidence from inside the house.

'His demeanour was still one of the man in control,' Small told the Mailonline.

Milat, now 70 years old, was surrounded by police at his western Sydney home and arrested

In prison, Milat, has been a troublesome inmate, having planned at least one escape and swallowing metal objects

'My impression was he didn't know what all the fuss was about. He was enjoying all the attention. He'd got away with it before and had the view he'd be back home for tea.'

'He thought he'd get off, but that was his last moment of freedom. He's been in custody ever since and I don't imagine, for a man who likes to be in control, he can be having a good time in jail.

Both Wayne Gordon and Clive Small have encountered Milat in prison, Small 'meeting' him in Supermax where the killer recognised the former detective, and castigated him for what he believed was Small's maligning of Milat's sister, Shirley.

Gordon interviewed Milat in Goulburn prison when he was investigating the murders of 20 young people from the Newcastle area in the NSW Hunter Valley region.

Several young women who disappeared over a 20 year period are strongly believed to have been murder victims of Milat, Gordon said.

'I went into Supermax to see him. He sat there, but then he put two and two together and remembered my name from the committal and his trial,' Gordon said.

'There was the tape recording of our conversation [at the trial] and then his appeal, and so there was a lot of colourful language. Yes, he said said the 'f' word several times and then he terminated the interview. He walked out.'
