A DAD who groped his teenage daughter in a black moment while drunk on home brew, has his conditional freedom.

He was sentenced to six months jail, to be released to the rising of the court that same day.

The dad allowed his teen daughter to drink alcohol at a neighbour's party and while the pair walked home he suddenly assaulted her, the District Court in Gladstone heard.

The dad, 42, pleaded guilty to the indecent treatment of a child under 16 in October last year.

Sarah Dennis for the Crown said the father let his daughter drink five rum and cokes and she felt "tipsy" before he later indecently touched her three times while they walked.

The touches were done through her clothes, the first when he grabbed her buttocks.

The girl pushed him away and the third time he grabbed her sexually she pushed him off and ran home to tell her mother.

Ms Dennis said at first the man denied indecently touching her saying "I just thought it was a friendly hug and that nothing happened".

"He says he can't recall details as he was intoxicated but says his daughter would not lie," Ms Dennis said.

The daughter's victim impact statement was put before Judge Michael Burnett, saying the consequences are far-reaching for her.

"She believes the impact will forever change her behaviour, particularly around him," Ms Dennis said.

"It is a terrible breach of trust by a father to his daughter. Intoxication is no excuse.

"It occurred over one short walk and she made it clear that what he was doing was unwanted."

Defence barrister Tom Polley said it was an isolated incident of a low-level nature, the touches done through her clothes.

Mr Polley said the dad had written his daughter a letter in answer to her question 'Why has this happened, Dad, what's going on?'.

It would stay with the Crown (DPP) if she later wanted to read it.

He described a man who was decent, hard-working and a good provider for his family, the assault very much out of character.

The man had recently become unemployed and feeling in a low place had resorted to alcohol.

"He was drinking home brew spirit all day. He says he was extremely intoxicated and has no real recollection of events," Mr Polley said.

"He finds himself at a loss as to what occurred.

"He instructs he is very sorry for the harm he has caused her and the destruction to his family."

Mr Polley said the father expressed his remorse and pleaded early to save his child from further angst.

Judge Burnett said the man, when confronted by his wife, told her he felt disgusted, that the behaviour wasn't like him, and did not know why he did it.

"A girl of 14 is particularly vulnerable at that stage of her adolescent life," Judge Burnett said.

He said alcohol seems to be a significant factor and relevant. And a letter from his wife before the court was supportive of him and recognised his genuine remorse.

The dad was now attending Alcoholics Anonymous and rehabilitation was important to both him and the community.

Accepting it was a low-level offence, Judge Burnett sentenced him to six months jail to be released to the rising of the court.

The sentence will hang over him for 18 months.
