Girl heard at school saying ‘my sister’s pregnant – I don’t know which brother’s the dad’
A schoolgirl was overheard telling a friend that her sister was pregnant and they didn’t know which of her brothers was the father – which led to a shocking investigation
A teenage schoolgirl unwittingly exposed the “world’s worst inbred family” when she confided to a classmate: “My sister is pregnant and we don’t know which of my brothers is the father.”
This sickening disclosure was overheard by a pupil who relayed what she had innocently heard to a teacher.
It was rare for any of the children from that family to attend school as they frequently relocated to different parts of Australia to evade scrutiny.
However, on this uncommon occasion when a child was present at school, the teacher reported what a student had told her to Australian authorities – leading to the exposure of one of the most shocking incest cases in July 2012.
Subsequently in court, the pregnant sister was given the pseudonym Tammy Colt, and it emerged that her baby daughter, Sally, died within two months of being born.
The infant was “extremely dysmorphic” with a thick short neck and low-set ears and succumbed to a fatal genetic condition called Zellweger Syndrome.
Sally’s father was not listed on the birth certificate – but Tammy disclosed that she had been involved with a younger brother for three years.
It is thought that both Tammy and the brother carry a genetic disease resulting from incest.
Tammy’s sister’s confession at school triggered a chain of events with enormous ramifications – and below we examine the notorious Colt family.

Following the appalling revelation at school, raids were ultimately conducted on a remote farm. Investigators unearthed an incestuous cult family consisting of 38 related individuals.
They were living in abject conditions, and the inbreeding had led to some of the children being severely disabled, unable to speak or even see.
The entire situation began with two great-great-grandparents who managed to go unnoticed for years in the secluded farming community.
Tim and June, siblings, tied the knot in 1966 in New Zealand before relocating to Australia.
Their seven children (Martha, Frank, Paula, Cherry, Rhonda, Betty and Charlie) endured sexual abuse from siblings, cousins, an uncle, fathers and grandfathers.
The family resided in “deplorable” conditions, lacking running water and toilets.
It was discovered that only one of the children was not fathered by a blood relative.
Tim, the patriarch of the incestuous family, fathered children with one of his daughters and even one of his granddaughters.
In 2012, social services instructed them to improve their living conditions, before it was decided that 12 children aged between five and 15 needed to be removed due to significant risk. Some of the children were placed with foster families.
Martha, the youngest child of Tim and June, shared a bed with her brother, Charlie, and they had five children together.
A massive court case was launched against the family members, with charges including incest, child sexual abuse, indecency against a child and perjury.
Despite eight members being taken into custody following their arrest in 2018, only four have been handed prison sentences.
Martha, her daughter Raylene, and her sisters Betty and Rhonda, were accused of providing false information regarding the paternity of their children.
In a chilling Facebook post, she shared a photo with two of her female relatives in 2018, captioned: “Love makes a Family.”
Rhonda received a 14-month intensive corrections order (ICO) for perjury, while Raylene was sentenced to 16 months for the same crime.
Betty, on the other hand, was found guilty on four counts of perjury, one count of lying under oath, and one of perverting the course of justice, leading to a 14-month prison sentence.
Tim Colt’s son, Roderick, was convicted of raping his niece, who was also his half-sister. His victim was named Petra, the child of Tim and Betty.
Martha admitted guilt to five counts of perjury and one count of making a false statement under oath.
It is believed that Betty now resides in New South Wales with a son in his twenties.
A total of 80 charges were levelled against eight members of the Colt family, but many were subsequently dropped.
Charlie Colt faced 27 charges, but he was cleared of two charges before being acquitted.
After their exposure, some members of the incestuous family joined social media, but it appears they are now living under the radar, much like when Tim Colt was at the helm.
Tim, who outlived his wife, passed away in 2009, before his family relocated to New South Wales, where a revelation in a schoolyard brought everything to light.
