A father has denied committing an act of indecency on his eight-year-old daughter, pointing to bank records which he says suggest he was working on the day of the alleged crime.
The 47-year-old Canberra man said from the witness box on Friday, the fifth day of the trial, that he had never touched his daughter sexually.
The Crown alleges the man told his daughter to come into his room, take off her pants, and get into his bed in the early afternoon of Sunday April 20, 2008.
He is then accused of putting his penis between her legs.
The girl reported the incident in March 2010, two years later, prompting a police investigation.
The court has also heard the daughter claimed her father committed a series of other sexual acts, none of which has attracted charges.
The man gave evidence on Friday that he was fighting with other family members in the period leading up to the daughter's complaint.
He said the dispute - which concerned living arrangements and a dog - had led to a heated argument with his son in early March, which became aggressive and physical.
The father took out an apprehended violence order against his son on March 8.
He told the court he went to see his daughter the next day, and then received a call from police on March 10 to arrange a meeting.
The daughter had made allegations to police that her father had sex with her.
He said that during the meeting the officers told him he was no longer allowed to see or contact his children.
The man, who suffered from significant depression and anxiety, says he broke down, locking himself in his car, and turning up his stereo loudly so that he could not hear the officers - who had become concerned at his behaviour.
''Most of that's a blank, I don't remember a lot of it,'' he told the court. He denied police claims that he was trying to self-harm using a needle, or by venting a gas bottle in his car.
The Crown - represented by prosecutor Trent Hickey - allege that his behaviour indicated a consciousness of guilt over the alleged crimes against his daughter.
But the father denies that was the case. ''Definitely not, I never touched my daughter in any way,'' he said.
He said he has no recollection of the day of the alleged offence in 2008.
The court heard the man had subsequently conducted investigations into his movements on the day in question.
He requested payment records from his work, which suggested he was not working.
But transaction records from his bank showed he used his bank card in Queanbeyan and at a Woolworths on the day he is alleged to have committed the act of indecency in his southside home.
He told the court those payments were consistent with his usual working patterns for a Sunday.
The father has not yet been cross-examined by Mr Hickey.
The trial continues on Monday before Justice Hilary Penfold.
