Former One Nation media adviser Sean Black faces a jail sentence after being found guilty of raping and assaulting a woman in Brisbane in 2007.

Black, a former staffer for ex-senator Malcolm Roberts, will be sentenced in Brisbane district court on 26 July after being found guilty of one count of rape.

He was also found guilty of two counts of assault occasioning bodily harm, but was acquitted of a third charge. Black did not apply for bail after the verdict.

Judge Glen Cash accepted a majority verdict for the rape charge from the jury, who had deliberated from Thursday afternoon to around 8.50pm on Friday, with one juror disagreeing.

The jury heard throughout the four-day trial this week accusations Black violently attacked the woman before raping her and threatening to kill her by shooting her in the head.

Black tried to pull the woman down a staircase and repeatedly called her a “filthy dog” in the first assault in April 2007, the court heard.

The woman alleges he raped her after she told him not to hit her any more.

The woman’s demeanour during her testimony indicated she was being truthful and medical evidence supported her version of events, crown prosecutor Brendan White said.

The jury rejected accusations by Black’s barrister, Rick Taylor, that the woman made up the allegations. He called her testimony “contrived” and said her evidence was “lies, I’ll call them lies because they are lies”.
