The father  pleaded guilty to maintaining a sexual relationship with his daughter but denied aspects of the Crown's case.

It is alleged that the abuse happened in the 1980s.

A disputed facts hearing took place in Launceston's Supreme Court in front of Chief Justice Alan Blow yesterday. 

The Crown alleged that the abuse occurred over several years, included digital penetration and oral sex on her and regularly happened whenever she   bathed.  

``He came in, rubbed soap on me, touched me down below . . .  (he'd) give me a cigarette - I just sort of stiffened up and let him do it,'' the victim, now in her 30s, told Crown prosecutor Peter Sherriff. 

``I'd sit there smoking while he rubbed soap on me.''

The woman, who cannot be identified, said they developed a signal where she would tap his leg for a cigarette and he would touch her vagina.

She said she would also stroke his penis if  she wanted a cigarette.

``That became a habit of what I'd do if I needed that cigarette,'' she said. 

Mr Sherriff said the man, who was often drunk, once asked his daughter ``could I break you in?'' but no sex ever occurred.

The man denied asking this. 

The daughter later confronted her father several times and on one occasion he admitted his conduct. 

``(He said) yeah, I did do it but you're just as much to blame, you encouraged me,'' Mr Sherriff said. 

The father also told her  that she'd be in trouble because she had touched his penis.

Through counsel  Emma Turner, the man denied saying this, the digital penetration and providing cigarettes for sexual contact.

Ms Turner suggested to the victim that she was actually about 12 when the abuse occurred and it only lasted for three weeks in total.

 ``Are you sure he put a finger in you?'' Ms Turner asked

``I'm pretty sure,'' the victim said.

``But not  100 per cent,'' Ms Turner said. 

``I'm  100 per cent sure,'' the victim said. 

In the witness box, the man said he told his daughter to stay out of his bedroom but she persisted in coming in.

He said he took ``full responsibility'' for what he did but only touched her when she was in grade 6.

``That should never have happened,'' he said. 

Mr Sherriff suggested he was trying to shift the blame on to his daughter, which he denied.

The mother said her daughter had been a problem child.

``She was quite a good kid when she was young . . .  as she got older she seemed to get worse and worse,'' the mother said. 

Justice Blow remanded the man in custody for findings and sentence on Thursday.
