Craig McLachlan’s long-time partner, Vanessa Scammell, says the pair are determined to clear the actor’s name over allegations of sexual harassment.

Speaking on Sydney radio, Ms Scammell insisted the Gold Logie winner was not the person the media painted him to be.

“Yes he’s mischievous, but one of his greatest assets is that he loves to make people happy and comfortable,” she told 2GB on Thursday.

“We will do everything we can to move through this and clear his name.”

Mr McLachlan filed defamation proceedings against Fairfax Media and the ABC after they published claims he sexually harassed a number of former colleagues.

In early January they reported several cast members of the 2014 run of The Rocky Horror Picture Show had accused the 52-year-old of touching or exposing himself to them.

The experience had been “rough and savage”, Ms Scammel said.

“The lack of humanity that’s been shown, I have found incredibly overwhelming.”

The couple were “side-swiped” when they became aware of the reports and the “shock was out of this world”, she said.

Mr McLachlan in January vowed to fight the sexual misconduct claims, saying his career has been “annihilated” by the accusations.

The former Rocky Horror Show star admitted the show’s backstage culture could be lewd, but insisted he is innocent of the allegations against him, in an interview with News Corp.

McLachlan says he didn’t understand why the allegations were made.

“By God I will fight this,” he was quoted as saying.

“And the truth, the truth will come out,” he said while not commenting on the specific allegations made against him citing legal advice.
