Former Hey Dad! Star Robert Hughes Seeks High Court Appeal For His Child Sex Abuse Conviction

Fairfax: Janie Barrett

Convicted paedophile and former Hey Dad! star Robert Hughes has applied for a High Court appeal, with the 67-year-old filing an application to the highest court in Australia through lawyers on Monday.

Hughes was found guilty of molesting four girls -- the youngest only six or seven at the time -- between 1984 and 1990.

In May 2014 he was sentenced to a maximum 10 years in jail, with a non-parole period of six years for the 10 charges relating to sexual and indecent acts.

The 67-year-old lost his first appeal in December in the NSW Criminal Court of Appeal. Hughes' lawyers argued the Crown relied on allegations of the former actor's inappropriate behaviour which was not related to the individual offences -- in particular the allegations Hughes slept naked in his change room.

Hughes’ lawyers are also fighting for a reduced sentence on the basis his past treatment in jail counts as additional hardship.

During Hughes’ first appeal the court heard fellow inmates showered the 67-year-old in urine and threw faeces at him, while the convicted paedophile also had boiling water thrown on him.

The former Hey Dad! star has since been moved from Goulburn to Long Bay Jail.

A date has not been set for the High Court to consider Hughes' application for appeal.
