A Brisbane father has been jailed for a minimum of two-and-a-half years after he sent ultrasound images of his unborn daughter to an undercover officer to show he intended to make child pornography when she was born.
Last week, the 25-year-old man pleaded guilty in Brisbane's District Court to possessing child exploitation material and using a carriage service to access child pornography material.
The court heard the father was arrested in January 2015 by Australian Federal Police officers after a tip-off from the FBI in the United States.
The man sent an ultrasound of his unborn child and 12 images of child pornography to an undercover officer, saying he intended to make his own child pornography with his daughter.
On the same day, he also told the officer his wife was due to give birth.
Police found the man in possession of 6,435 images and videos of child exploitation material across three devices.
Some were of cartoons, but thousands were of actual children and babies.
The court had previously heard many of the children were showing signs of distress and pain.
District Court Judge David Reid said it was the worst case of child exploitation material he had ever seen.
He sentenced the man to five years' jail, with a non-parole period of two-and-a-half years.
