Jason Daron Mizner, 44, has been jailed in Australia for 19 years for raping his girlfriend’s 2-year old daughter while she was in nappies.
Mizner recorded the incident and was only caught when he went to Thailand and left his bag home.
His girlfriend found the bag which contained videos of some of his exploits as well as notes on how to rape the children.
He pleaded guilty to the offence and will be eligible for parole in 15 years’ time.
The judge had to take a break as he found the video too disturbing and described it as an act of evil.
Mizner has already spent 11 years in jail for unconnected child sex offences.
Lawyers for Mizner wanted the court to take into consideration the number of years he spent in prison in Thailand as he suffered at the hands of his fellow inmates.
