Actor Craig McLachlan says he won't apologise for who he is, while denying indecent assault allegations from his former co-stars.
McLachlan faces charges relating to four women from the Rocky Horror Show, in which he played the lead role of Dr Frank-N-Furter.
The 55-year-old Gold Logie winner strenuously denies the allegations.
He recalled putting on a fruity and flamboyant demeanour for all co-stars backstage because that's who he was.
"I've always been outgoing, I've always been energised and enthusiastic and over the top in the workplace," he told his lawyer, Stuart Littlemore QC, in Melbourne Magistrates Court.
"I won't apologise for who I am."
He faces seven counts of indecent assault and six of common law assault.
Among the charges is an allegation he forced his tongue inside a co-star's mouth when it was not in the script.
McLachlan said it would have been "impossible" for him to indecently assault the woman on stage.
He broke out in song while giving evidence about the scene, and said he gave the woman a "brief, one-second kiss" as part of his performance.
The woman claimed she later told McLachlan "don't you ever do that to me again". He is alleged to have replied "you are nothing. I will end you", but disputes saying this.
McLachlan also said there was "not a word of truth" in another allegation he exposed his penis to the same woman backstage.
He went into detail about how this wouldn't have been possible, recounting the procedure for removing stage clothing including his jock strap.
He labelled another allegation that he hugged the co-star while aroused and without wearing any underwear "ridiculous".
Footage from one Rocky Horror Show performance was played in court, as McLachlan similarly denied claims he forcefully grabbed a woman's face on stage and then clapping angrily at her during the curtain call.
Earlier this week, he described one of his accusers as "the most vulgar individual" he'd ever met.
McLachlan said the atmosphere between cast members had been playful and affectionate.
He claimed one of the women straddled him with an inflatable porpoise, and gifted him the toy.
McLachlan has played the role of Dr Frank-N-Furter as far back as 1992.
During one 1990s performance of the show, prosecutors said McLachlan slid his stiletto up the backside of narrator Molly Meldrum.
"I had manipulated my dick out of my g-string and I was wildly swinging my member," the court was told McLachlan later recounted.
This is not the subject of any charges.
The hearing is due to continue on Thursday.
