A member of the incestuous Colt family has been found guilty of raping his niece - who was also his half-sister - in the years before authorities found the clan living in a squalid bush camp.
Frank Colt, 51, was one of eight family members arrested in April 2018 as part of a long-running child sex abuse investigation, sparked by the discovery of nearly 40 relatives living in squalid circumstances in 2012.
The New South Wales District Court found on Tuesday that Colt attacked his relative, known by the pseudonym Petra, when she was 17, in the back seat of his car, during a visit to the family farm near Yass.
The victim's evidence was 'simply and matter-of-factly put' and was powerful and credible given her upbringing and rudimentary education, Judge Gina O'Rourke said.

'She did not try to gild the lily and attribute other acts to the accused,' Judge O'Rourke said.
Colt maintained his right to silence throughout the investigation and trial, with his barrister arguing the sexual intercourse never happened.
Colt, who has the same father as his victim, was remanded in custody ahead of his sentencing.
He had faced a single rape charge, with others dropped.
As of early last year Colt had been bailed to a backpacker hostel in Glebe, in Sydney's inner west.
Police had famously found dozens of members of the family living on a farm in remote Boorowa, New South Wales in 2012, after a conversation was overheard about family sex in a school playground.

Authorities took a dozen children into care and police investigations have continued for close to a decade.
The itinerant family were well-known throughout country New South Wales and South Australia.
The family have been given the pseudonym 'Colt' by the court.
Other members of the clan remain before the courts.
