Judge tells Queensland man it has been a battle to get the video footage of his shocking acts out of her head

Queensland child rapist Jason Daron Mizner will spend at least 15 years behind bars for grooming and sexually abusing a two-year-old girl, as well as filming the assaults.

Mizner pleaded guilty to 65 child sex offences, including more than 30 counts of rape, and videotaping the assaults.

The 44-year-old formed a relationship with the girl’s mother, before committing the offences over several months.

While he was on a holiday in Thailand, the girl’s mother found the videos he had made and a range of other unrelated child exploitation material.

Mizner stayed on in Thailand, where he formed another relationship with a local woman before assaulting her young daughter there too, and being arrested by Thai authorities.

He served 11 years of a 35-year sentence and was deported when released on bail last year, and Australian authorities arrested him when he returned to Brisbane.

In sentencing Mizner on Friday, the district court judge Leanne Clare said the time in the Thai jail could be taken into account, sentencing him to 19 years in an Australian prison – for a total of 26 years in custody across the two countries.

The sentencing was delayed on Tuesday after the judge viewed some of the footage of the rapes, which she said were shocking and required her to put some time between viewing them and passing judgment so as not to cloud the sentence.

On Friday, she said there was no evidence that Mizner had remorse for what he had done.

“It was [the girl’s mother] who found the recordings. That content would be excruciating for most people,” she said

“I only watched a portion and it has been a battle to get the vision of your offending out of my head. I cannot imagine the horror of it for [the girl’s] mother.”

Mizner must serve at least 15 years of his 19-year sentence, making him eligible for parole in 2031.
