Gable Tostee can be heard breathing heavily after New Zealander Warriena Wright disappears from his Gold Coast balcony, in the explosive audio recording played in court today.

He can also be heard attempting to make a phone call that goes unanswered.

He then apparently leaves the apartment building and calls his father, Gray, to come and pick him up.

"Hello Dad, I might have a bit of a situation," he says.

After explaining what happened, he goes on, "She kept beating me up and whatever and, um, I locked her out on the balcony and I think she might have jumped off.

"There's a million cops around my building, I'm f***ed.

"I don't know what to do.

"I didn't cause this, I didn't push her or anything.

"I'm just walking around the area and there's a million cops around the area."

Wright plunged 14 floors to her death off Tostee's Surfers Paradise apartment on August 8, 2014. Tostee has pleaded not guilty to the murder charge.

Tostee sounds calm throughout the conversation with his father.

When the elder Tostee comes to collect him, he asks if he needs to go to hospital.

"Why," his son asks.

"Well, it's traumatic," he responds.

Tostee explains to his father that he and Wright had watched a movie and had sex throughout the course of the evening but that she drank heavily.

"The last thing I remember is trying to hold her down and she ran out onto the balcony. I hope I just imagined it," he says.

"I might have locked her on the balcony ... I absolutely did not throw her off my balcony. I would never do anything like that."

Despite the police presence around his apartment building, Tostee apparently did not yet know Wright had died.

"God, I hope she's not dead," he says. "What if she's dead? What if she jumped?"

His father replied, "Don't worry. There's nothing you can do about that."

"This is so f***ed up. Why has this happened to me," he asks.

As he continually attempts to call his lawyer, Tostee can be heard fearing he does not have proof he did not push Ms Wright off his balcony.

"I do have photos of me and her, like, selfies. But I don't know if I have any proof of her being aggressive," he says.

"The truth comes out," his father replies. "It will."

The jury in the murder trial earlier heard the last chilling moments of Wright's life, as the accused killer allegedly locked her on his balcony after she was growing increasingly aggressive.

"No, no, no, no, no. I want to go home. Just let me go home," she is heard saying on the audio.

"I would, but you've been a bad girl," he replies.

Wright's screams pierced the courtroom, as she appeared to be begging for her life.

Tostee can be heard asking a slurring Wright to leave his apartment, in an increasingly threatening tone.

"You goddamn psycho b****. I'm going to let you go, I'm going to walk you out of this apartment, just the way you are," he says.

"You're not going to collect any belongings. I'll slam the door on you. You're not going to pull anything or I'll knock you the f*** out."

A muffled scuffle ensues between the pair, in which Wright repeatedly cries, "no, no, no no" and "I want to go home. Just let me go home."

The noise is silenced by the sound of a sliding door, which fits with the Crown's contention that Tostee locked her on his 14th floor balcony.

Within moments, the 26-year-old had fallen to her death.

Yesterday the first part of the explosive audio recording was played in court, capturing Ms Wright's final hours in Tostee's Gold Coast apartment.

It revealed the New Zealander was drunk, at times incomprehensible and repeatedly violent to the man charged with her murder.

"I've met some weird people on Tinder," the 30-year-old murder accused was heard to say, as the drunk Ms Wright apparently swings in and out of violent episodes towards him.

The trial, before Justice John Byrne, is continuing.
