The next generation of Australia’s most inbred family, who were discovered living on a filthy remote block in the hills of country NSW a decade ago, have begun asking questions about their past – including if one girl’s father is also her uncle.
The 40-strong Colt family were discovered by authorities living without electricity, running water or sanitation near the town of Boorowa, 150km north of Canberra, in 2012.
Their story of incest, depravity and squalor shocked the world when authorities discovered the clan living in isolation on a filthy bush block in the hills, and the NSW Children’s Court found the case so disturbing it decided to publish a lengthy judgment of its findings.
Choosing pseudonyms to protect the children, including Ruth Colt, the Court’s unprecedented 34-page dossier on the family nevertheless contained horrifying detail of intergenerational incestuous behaviour and neglect conducted in secret for decades.
Ruth, one of the youngest members of the family and now about 19, has surfaced on social media, posting about her loneliness, how she misses her siblings and directly questioning the man believed to be both her father and uncle.
‘Hi,’ she wrote to her dad on social media. ‘Are you and mum brother and sister?’
She then wrote, ‘do you know who my dad is?’ and ‘hi uncle how are you’.
Ruth’s mother Martha and her aunt Betty were the matriarchs of the clan. The young woman was just nine when her family’s terrible secret was uncovered by authorities, after a chance remark in the schoolyard by one of her siblings.

The Colt’s farm was in the hills behind Boorowa, difficult to access and kept the family socially isolated which is what they enjoyed – until authorities uncovered their terrible secret
DNA tests found the Colt family, a pseudonym appointed by the Family Court, included at least 11 children who had been fathered by a relative of their mother.
Meanwhile, authorities found the related children were themselves allegedly involved in rampant sexual activity, according to court records.
The 38-member clan had moved to NSW after spending years travelling around performing at country music festivals and living at remote locations in Western Australia, South Australia and Victoria.
They may have moved from state to state to avoid detection.
The original 2013 judgment by NSW Children’s Court president Judge Peter Johnstone found that the Colts were descended from a New Zealand brother and sister.
The siblings were the parents of June Colt, who was the wife of Tim Colt, the family patriarch and lead singer of the family band, which produced tunes such as one titled ‘Songs of Love’.

Tim Colt, who died in 2009, fathered seven children with his wife, June, but also fathered up to 16 children with two of his daughters and probably one with his granddaughter.
As the family tree drawn from Justice Johnson’s bombshell judgment on the Colt case shows, while Tim was having sex with his daughters, other daughters and granddaughters were having sex with their brothers, uncles and cousins.
Incestuous sexual activity between the relatives living in the squalid camp near Boorowa was rampant, according to Justice Johnson’s report.
And it produced deformities in the children born inbred.
These included low-slung ears or misaligned eyes, and children who look decades older than they should.

In 2021, one of the children who did attend a local school was heard tell another student that one of his sisters was pregnant, and that they didn’t know which male relative had fathered the child.
Colt women had always avoided doctors when pregnant.

When authorities finally descended on the Boorowa farm, what they discovered was both shocking and traumatising for nurses, doctors and social workers.
Living on the squalid farm were seven adults and more than 30 children, sleeping in a series of tents, sheds and lean-tos draped with electrical wires hooked up to a generators.
Some children’s speech was so stunted they could not be understood. They had fungal infections, and had never used a toilet or shower.
They were years behind at school, if they had attended at all. They tortured the genitalia of animals and had sex on the farm with their cousins, uncles and aunts and played sex games.

Ruth’s mother Martha openly shared a ‘marital bed’ in one of the tents with her brother, Charlie.
The family were socially isolated, and the children and adults appeared perfectly happy with one another, but that blissful ignorance ended when the NSW Child Protection Squad leveled 80 charges against eight Colt adults, including sexual abuse, but many were later dropped.
Three of the Colt sisters were charged with perjury for lying about their children’s paternity, when the DNA tests had proved their ‘homozygosity’, or identical gene patterns of their parents.
Removed from the farm and their parents, the children were placed in foster care, from which some of them tried to escape.

Betty was found guilty of two charges relating to the attempted kidnapping of two of her children from authorities and served time in jail.
In 2018, five sons of Betty and her sister Martha, posted videos expressing their desire to be restored to the care of their mothers.
Still hardly intelligible, the boys then aged between 13 and 18 claimed that while in care they have been ‘bashed’, ‘beaten up’ and given ‘a hiding for not washing properly’.
The five boys who made the video recordings, Billy, Brian, Karl, Jed and Dwayne, said they were unable to fit into society.
Martha was more recently reunited with her three sons once they had reached adulthood and has posted photographs of herself with them on Facebook.
Several social media posts of Colt family members like Ruth seem to indicate a yearning to find out about her past and be reunited with her family.
On her Facebook page, she says that she misses her sister and that seeing her and others would make her happy.
On TikTok she says she would like to visit her sibling. It features video of herself dancing along in a room to emotional songs.
The complicated family history of the Colts is believed to go back further than four generations, and will probably never entirely be told.
