The family, who are being called the Colts for legal reasons, lived in squalor, but they had a bigger secret which they had been keeping to themselves for generations. The whole Colt family were regularly practising incest between parents, children, aunts and uncles.
The fear of being discovered had caused the family flee New Zealand in the early 20th century, they moved around Australia and eventually settled in New South Wales.
When officers entered the family’s home dirt caked the surfaces of stoves and cooking facilities, rotten vegetables lay in a refrigerator and a kangaroo was sleeping on one of the children's beds.
Exposed electric wires, bags of rubbish and chainsaws lay about the sheds; there were no baths, showers, toilets or running water.
The children were unwashed shy and made little eye contact.
Few were capable of intelligible speech and almost all had fungal infections in their feet.
Some had oddly-formed features, which scientific tests would later reveal was a result of "homozygosity" or identical gene patterns of both of the children's parents.

Four generations of depraved interbreeding had left the children genetically deformed and few were capable of intelligible speech
Years of interrelations had resulted in some of the children misshapen and intellectually impaired.
They were profoundly neglected, to the point they didn't know how to shower or use toilet paper, and were covered in sores and racked with disease.
Under the eye of the family matriarch, Betty Colt, who slept in the marital bed with her brother, the children copulated with each other and with adults.

Left to their own devices, brothers and sisters, uncles and nieces, fathers and daughters, were all engaging in sexual activities.
When the girls became pregnant, they would often simply miscarry on the farm, not wanting to arouse suspicions among doctors or health professionals.
The Colt women originally claimed that outsiders had fathered their children - itinerant men, a wheat worker and a Swedish backpacker but tests proved otherwise.
When they finally managed to get test swabs into a laboratory, geneticists uncovered a family tree which was a nightmare of "homozygosity", a genetic condition which occurs when a child's parents are closely related.
Eight of the Colt children have parents who were either: brother and sister, mother and son or father and daughter.
A further six have parents who were either their aunt and nephew, uncle and niece, half siblings or grandparents and grandchild.
Three of the daughters - Rhonda, 47, Betty, 46, and Martha, 33, and at least one of the sons, Charlie, form the elder members of the family group in the New South Wales bush camp.
Betty had 13 children.
One of her children, Bobby, 15, was fathered either by her father, whose name was Tim, or the brother she was sleeping with.
Four more of Betty's children were fathered by a close family member.
Betty's eldest child, Raylene, now aged 30, has a 13-year-old daughter, Kimberly.
Raylene insists Kimberly's father is a man called Sven, from Sweden or Switzerland but testing proved that her father is either her half brother, an uncle or a grandfather.
Betty's second oldest child, Tammy, now aged 27, has given birth to three daughters, one of whom died from a rare genetic disorder, and all of whom, she eventually admitted, were fathered by her closest brother, Derek, 25.
Betty's younger sister, Martha Colt, 33, has five children, four of whom were fathered by her own father, Tim, or by her brother, and another who is the product of a union with a close relation.
It was the 10 youngest of Betty and Martha's children, and Raylene's daughter, Kimberly, 13, who ran wild in a sexual spree about the property.
Betty's children, Bobby, 15, Billy, 14, Brian, 12, Dwayne, 9, and Carmen, 8, all have parents who are close family members.
Martha's children, Albert, 15, Jed, 14, Ruth, 9, and Nadia, 7, are also the product of closely-related parents.
Interviewed by child protection workers and psychologists, they told of a virtual sexual free-for-all.
Ruth and Nadia said Albert, Jed and Karl showed them pornographic magazines, touched their breasts and Albert had sexual intercourse with them.
Not only were the children dirty and unschooled, they had multiple health problems and no concept of hygiene.
Betty's son Bobby Colt, 15, had a walking impairment, severe psoriasis and needed urgent dental work.
His speech was not understandable. He wet and soiled the bed and his learning ability was at kindergarten level.
Martha's sons Albert, 15, and Jed, 14, were similarly challenged with their speech, personal hygiene and lack of dentistry.
Betty's 14-year-old son Billy was underweight and not growing properly, had hearing and sight problems, spoke unintelligibly, had an intellectual disability and could barely read or count.
Kimberly Colt, 14, Betty's grandaughter Raylene, was underweight and unable to clean her teeth, use toilet paper or comb her hair.
She had urgent dental problems, hearing, speech and sight issues and was unable to read or write.
She threatened to cut off a caseworker's fingers.
Betty's son Brian, 12, did not understand showering.
He had extensively decayed teeth, and borderline normal hearing.
His eyes were misaligned and he could not read, write, or recognise numbers.
Martha's nine-year-old daughter Ruth was neglected and malnourished.
She was unable to bathe or dry herself. She did not know how to use a toilet or what toilet paper was.
Her features were dysmorphic. She could not read or write, couldn't hear well and her speech was fragmented and stunted.
Kimberly, 13, reported sexual contact with her uncle, Dwayne, who was nine years old while her aunt, Carmen, 8, watched on.
Sisters Ruth, 7, and Nadia, 9, had sexual touching with their brothers Albert, 15, Jed, 14, and Karl, 12.
On one occasion, three brothers aged 14 years and under tied their sister, 8, and niece, 13, naked to a tree.
Albert, Jed, Karl, Bobby and Billy admitted they tortured animals, including puppies and cats. Carmen said her father was her uncle Charlie.
The children also mutilated the genitalia of animals
The accounts of incestuous underage sex fill pages of court documents.
Clinicians took mouth swabs from the children and geneticists deduced five of the Colt children had parents who were "closely related" and another five had parents who were "related".
Interviews with the parents and other members of the family revealed an astonishing tale.
In the fallout from the discovery of the Colt Family, some children have been placed with foster families, others are in treatment programs for sexualised behaviour and psychological trauma, and they have some contact with their parents and siblings.
They have made progress with schooling and hygiene.
The mothers have taken varying degrees of responsibility for the neglect, the incest or intra-familial sexual abuse which allegedly took place in the family.
One of the mothers is due to face court on charges of procuring the removal of a child from care and recruiting a child for a crime, and further charges are expected.
Just wow. What the fuck have I just read like.. imagine pulling one of the girls on a night out and her going "my dad is my brother" like wut.
I feel sick along with confused after reading that, also a little bit angry. Going to be a good case study of genes but still at a human cost not worth it.
