A verdict has been reached in the murder trial of Gable Tostee over the death of New Zealand tourist Warriena Wright, but it is yet to be announced.

The Supreme Court hearing in Brisbane reconvened at 2:30pm, with Tostee hugging his father before he entered the dock.

On Thursday morning, the jury began a fourth day deciding whether Tostee killed Ms Wright, whom he met via the dating app Tinder on the Gold Coast in 2014.

The jurors asked for advice from Justice John Byrne four times since beginning deliberation on Monday afternoon, and they admitted to problems with reaching a verdict.

Tostee pleaded not guilty to killing Ms Wright, 26, who died after falling 14 floors from his Surfers Paradise apartment in August 2014.

Deliberations continued until 6:00pm on Wednesday before jurors were finally sent home.

Jurors posed their fourth question to Justice Byrne yesterday afternoon, asking whether Tostee's language could be considered as force.

"The short answer is no," Justice Byrne replied.

He told the jury it should only be concerned about the "physical force" used by Tostee, and whether or not it was more than reasonably necessary.

Tostee restrained Ms Wright and locked her on his apartment balcony.

The crown argued that when Tostee locked her out, Ms Wright felt so intimidated she died trying to escape.

The defence said Tostee was trying to de-escalate the situation, arguing Ms Wright's actions were not rational or foreseeable.

The court heard a recording Tostee made on the night Ms Wright fell to her death, in which he is heard saying: "You are lucky I haven't chucked you off my balcony you goddamn psycho little bitch."

Justice Byrne has previously told the jury the degree of Ms Wright's intoxication should bear on their consideration on whether her decision to climb over the balcony was "a reasonable, rational or proportional response to the accused's conduct".

Responding to their suggestion on Tuesday they could not reach a decision, Justice Byrne said experience showed juries could often agree given time.
