A SISTER and a brother who had kids together have been arrested and the children removed.
According to Australian news, the two had been living as man and wife on a remote family farm in New South Wales, south Australia.
Cops have given them fake names to protect the identity of the kids, calling them Martha Colt (38) and her brother Charlie Colt (age unknown).
They were found with five kids between the ages of 11 and 20, but cops are still investigating whether they are all the product of sex between Martha and Charlie.
In 2012, cops first bust 38 members of the Colt family living on the farm, many of the siblings allegedly having sex with each other or even the kids. Several children were removed at the time.
Cops swooped on the farm and other places members of the Colt family lived for a second time in April.
Siblings and nephews of Martha and Charlie now also face charges of sexual intercourse with children, indecent assault and incest.
Cops say the five kids are in a bad way. They have hardly any education, were dirty and didn't know how to do things like brush their teeth or use toilet paper when they were found.
Many of them also have twisted facial features and walk strangely, probably because of genetic problems resulting from incest.
Martha is in a women's prison in western Sydney. On Wednesday, she applied for bail.
The Colts are unlikely to face trial until late 2019.
