The match was played before 15,000 people and televised on the Nine Network's GEM channel.
"I realised I was marching into a lion's den with this tie I had slavishly painted those colours on and splashed with glitter," he said.
"It was a choice moment the buffoon chose, big crowd, live television, whoever this person is you have to admit they have theatrical timing, they chose their moment perfectly.
"Clearly one individual among the fans felt I was a little too fabulous - his problem, not mine.
"I learned a very long time ago not to value the opinions of people for whom I have no respect."
The outrage expressed by fellow performer and his co-parent, Jacqui Dark, has sparked a rainbow tie campaign on social media.
"He's an extraordinary singer and did a magnificent job. He nailed the anthem. He looked fantastic," she said.
"He also wore a snazzy rainbow tie to show his support for marriage equality, an issue on which the government of this country is embarrassingly backward.
"The applause died down and a solitary, angry male voice in the crowd yelled 'Faggot!."
"I am beyond stunned by this. Beyond hurt and beyond angry. He took it in his stride, texting me that it had happened and adding 'My work here is done'".
For Breen the biggest concern were the number of children who would have heard the bigotry.
"The only thing worrying me is just how many families and how many kids were there, even if I had been wounded by it I am big and ugly enough to get over it but I don't enjoy the notion that kids might think it's the normal thing to do," he said.
Rod Laver Arena officials told Daily Mail Australia that no complaint was made on the night and no person identified and that they were only alerted after the event via social media.
"No reports were made to any our our staff, that's disappointing because the individual would have been removed from the arena, as that would be deemed anti-social behaviour."
"It's not basketball's issue, I knew I was stirring the pot by wearing this tie but the sad reality is that is something i contend with very often," Breen said.
"It didn't affect me in the slightest, all I thought at the time is 'oh good someone saw my tie', I just got on with singing."
Jacqui Dark had hoped that someone in the crowd would have taken a stand because it was heard "clear as a gunshot."
"Heckler, you are an embarrassment - everyone else in the crowd who didn't comprehensively shout this bigot down, you are also an embarrassment, she said.
"All that is necessary for the triumph of evil is that good men do nothing. You did nothing. Through your inaction, you silently condoned this man's behaviour."
Kanen Breen has clearly taken the controversy in his stride.
"I am deeply moved by Jacqui's words, and by the words of many other dear friends which followed - so many fine people who want this nation and this world to move in a better direction," he said.
"Fight on darlings, be fierce and fantastic and love each other and don't take no guff from the cheap seats."
