Hunter MP Joel Fitzgibbon has labelled comments about women and gay people by One Nation candidate Stuart Bonds "appalling".
Nine News reported on Thursday that Mr Bonds had said in a now-deleted YouTube video: "The only thing worse than a gay person with power is a woman. I don't have a woman boss, and I don't have a gay boss, and there's a reason for that."
The video was reportedly posted on the YouTube channel of Mr Bonds' wife, Sini Ariell, a Finnish model, blogger, tattoo artist and former reality TV contestant.
Mr Fitzgibbon denounced Mr Bonds on Friday and said the 33-year-old mine worker would pay for his comments at the ballot box next month.
"His comments were appalling, and I have no doubt the overwhelming majority of our electorate will take the opportunity to send him that clear message on May 18," the Labor incumbent said.
The ABC quoted Mr Bonds as saying his comments had been taken out of context.
"There's no context to the conversation; there's no laughter," he is quoted as saying. "There was no general feel for ... the jest with which it was said in.
"I absolutely have no problem with homosexual people. I am married; I have a young daughter. Also, the leader of my political party is one of the most honourable, strongest women I've seen."
The ABC also quotes him saying "ordinary people ... not groomed" for politics will be scared off from running for office if they are subjected to such media scrutiny.
Nine also reported that another deleted video showed Mr Bonds "raising questions" about the 1996 Port Arthur massacre, echoing comments by One Nation leader Pauline Hanson.
The Nine report said the political novice had voiced doubts about the shooting and sea burial of Osama bin Laden and the September 11 terror attacks in 2001.
In response to the Nine coverage, Mr Bonds posted one of the videos on Facebook on Friday.
In the March 28 video, Mr Bonds defends Ms Hanson's right to free speech and criticises the nature and timing of the Al-Jazeera undercover operation that publicised her comments on Port Arthur.
He raises well worn conspiracy theories about the deaths of Bin Laden and John F Kennedy and what he takes to be erroneous US media reporting about "collusion in the Russian election".
But, taken in context, his comments in the video are a defence of free speech and, ironically, what he regards as selective quoting by the media. He does not directly endorse nor reject the conspiracy theories but defends the public's right to "question everything".
The Herald has not seen the video in which he talks about women and gays.
Mr Bonds was not available for comment on Friday.
