Tostee trial: 'you beat me up'
Gable Tostee's murder trial hears Warriena Wright had "no other means of escape" after he locked her on the balcony. Nine News
An audio recording Mr Tostee took with his phone captured an altercation between the pair as well as the 26-year-old's eventual death, falling 14 floors from his Surfers Paradise unit.
The court heard Ms Wright saying she wanted to leave Mr Tostee's apartment a number of times but the two continued to talk and drink.
"Are you going to f---ing untie me because I will f---ing destroy your jaw," Ms Wright says.
"I should have never given you so much to drink," Mr Tostee says later.
Ms Wright threatened to call the police while Mr Tostee accused her of beating him up for no reason.
The remainder of the recording will be played to the jury on Tuesday and includes Ms Wright's final moments before she died.

The court heard it was not alleged Mr Tostee threw Ms Wright to her death but intimidated and threatened her so greatly she felt the only way to escape was to climb down from his locked balcony.
Prosecutor Glen Cash said Mr Tostee put Ms Wright out on the balcony after she threw some decorative rocks at him and hit him with a telescope.

Ms Wright's mother Beth broke down as the court heard how her daughter was allegedly choked as Mr Tostee restrained her.
"You're lucky I haven't chucked you off my balcony, you goddamn psycho bitch," Mr Tostee is heard to say in the recording.

"You're not going to collect any belongings, you're just going to walk out.
"If you try to pull anything I'll knock you out, I'll knock you the f--- out - do you understand?"
Gabriele Collyer-Wiedner, who lived in the unit directly below, had been woken about 2am to the sound of banging furniture when she looked out onto her balcony and saw Ms Wright's feet pointing at her.
"Legs came down and dangled in the air," she told the court.
"I froze there, then the body fell on my balcony railing.
"I screamed and somebody else screamed, I assumed it was her voice".
The court heard Ms Wright fell to the driveway below.
In his opening address, defence barrister Saul Holt QC said Mr Tostee did not choke Ms Wright but was within his legal right to protect himself and his property by restraining her.
"She is outside, he is inside and he has caused a locked door to be between the two of them," Mr Holt said.
"What happened in this case is nothing like murder or manslaughter, it doesn't fit."
The court heard after Ms Wright fell to her death Mr Tostee attempted to contact a lawyer and called his father.
"She kept beating me up and whatever," Mr Tostee told his father in the recording.
"I forced her out onto the balcony and I think she might have jumped off."
The trial before Justice John Byrne will continue on Tuesday.
