Mum-of-seven Akon Guode has admitted to killing three of her children by driving into a deep lake, a court has heard.
She has also pleaded guilty to the attempted murder of a fourth child, who was in the car at the time.
Akon killed one-year-old Bol and four-year-old twins Hanger and Madit back in April 2015 when she drove her car into a lake in southern Australia.
Six-year-old Alual, thankfully, managed to survive the ordeal.
According to the BBC, Guode, who is originally from South Sudan, pleaded guilty to one count of infanticide, two counts of murder and one count of attempted murder in the Supreme Court of Victoria.
The 37-year-old has been living in Australia since 2008, and was described by her husband, Joseph Manyang, as a "loving mother".
A witness told the court that she saw the car deliberately being driven into the water.
Akon is due to appear in court for her trail in January.
