The Gold Coast man acquitted of murdering New Zealander Warriena Wright has opened up about the night of her death, the subsequent trial, and his life since being found not guilty.
In a revealing interview with The Gold Coast Bulletin, Mr Tostee - who is now known as Eric Thomas - spoke out about why he locked Ms Wright on the apartment balcony she later fell 14 floors to her death from.
"We don't act with hindsight," he said.
"You think, 'Well, there is a door there that can separate the two of us.' You're being attacked. You think you're doing the most sensible thing and you think that will just defuse the situation.
"Something completely freakish, completely unexpected happens... It's totally unforeseeable."

Addressing questions on why he didn't just push her out the front door rather than onto the balcony, Mr Tostee said that door was closer - and explained that he hadn't even considered that it might later result in her death.
"You dont weigh up, 'Well, is this person going to climb off a 14-floor balcony?' That doesn't occur to you... it doesn't even come into the equation," he said.
"You think, 'If I can just get the person away from me, figure out what to do next, call security or management or something to take her away properly.' I mean that's more responsible than just shoving a drunk person out the front door to make a ruckus to the neighbours or possibly get herself in trouble or injured.
"There is nothing inherently unsafe about a balcony, unless you climb over it."
Mr Tostee also opened up on the trial, an experience he refers to as "the apocalypse" - and while he admits a lot of people are still likely to see him as a murderer despite his acquittal, he says his friends "know the truth".
"The people who criticise me or hate me the most are the ones who know me the least. It's not surprising because ignorance is so much louder than understanding."
He says he may now consider writing a book about his experiences, saying his experiences with the media, justice system and in the public spotlight have left him with "a lot to be said".
"You gain a certain insight into things," he said.
"It can't exactly be summed up in a few words. If it could help to inform people or share an experience someone might not know about, then it could be an idea. But I struggle writing an essay, so..."
Mr Tostee has raised eyebrows lately, making controversial comments on International Women's Day, and rebuffing a Facebook user's claims that he murdered Ms Wright by saying "the only thing I murder is p*ssy".
