Longer jail term for child abuse material

A Queensland man convicted of accessing and transmitting child exploitation material has had his jail term extended following an appeal by the Director of Public Prosecutions.

Daniel Leslie Cooper used messaging apps and social media to transmit, solicit and access child abuse material between January 2016 and November 2017.

He pleaded guilty to eight offences and was sentenced to 12 years' imprisonment in February last year.

Images showing children subjected to the "most vile and despicable depravity" and the fact Cooper played "an active role in the child pornography market" were highlighted as key features of the case relevant to the ultimate sentence.

"The respondent's self-professed sexual interest was in the abuse, exploitation and degradation of very young children, particularly babies and toddlers," the Court of Appeal judgment states.

The Commonwealth Director of Public Prosecutions described the initial head sentence and non-parole period as "manifestly inadequate".

The 12-year sentence and a non-parole period until February 2026 will be set aside and replaced with a 16-year sentence under judges' orders delivered on Friday.

Cooper will now be eligible for parole in February 2030, 10 years on from the date of his sentencing.
