Neighbour saw NZ tourist fall from balcony

Gable Tostee's downstairs neighbour saw Warriena Wright's legs dangling from the balcony just moments before the New Zealand tourist plummeted to her death, a trial has heard.

Tostee, 30, has pleaded not guilty in the Brisbane Supreme Court to murdering Ms Wright in the early hours of August 8, 2014 at his high-rise Gold Coast unit.

Crown prosecutor Glen Cash alleges Tostee did not throw the 26-year-old 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.

Gabriele Collyer-Wiedner, who lived in the unit directly below Tostee's, told the court on Monday she woke about 2am to the sound of banging furniture.

Ms Collyer-Wiedner said she looked out onto her balcony and saw Ms Wright's feet pointing at her.

"Legs came down and dangled in the air," she said.

"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 14 floors to the driveway below where her body was found by first responders.

She had been drinking at Tostee's flat after meeting him on Tinder during her two-week holiday in Australia.

Her sister Marreza Wright told the court Ms Wright had Facebook messaged her that night saying she had found "an Australian Sam Winchester", a character from the TV show Supernatural.

The last message she received from Ms Wright was a poorly-lit selfie with her and Tostee at his unit.

The trial has heard an audio recording made by Tostee on his mobile phone captured an altercation between the pair as well as Ms Wright's eventual death.

Her mother Beth Wright broke down as the court heard how her daughter was allegedly choked and restrained by Tostee.

The trial continues.
