A mystery blonde who has identified herself as Gable Tostee's girlfriend has attacked Warriena Wright as a "phycho [sic] drunk" on social media.

Kiwi Lizzi Evans joined a Facebook discussion group created during Tostee's Supreme Court trial for the murder of Wright, where she repeatedly made posts in defence of him.

In a series of private messages with two members of the group - obtained exclusively by news.com.au - Evans said she was Tostee's partner and that they had been seeing each other for "quite a while".

In a number of posts made throughout the trial, Evans not only attacked Wright, but said her partner planned to sue a number of media organisations for defamation.


Wright plunged to her death from Tostee's 14th-storey Gold Coast balcony while on a Tinder date with him in August 2014.

Evans bragged her partner stood to make "quite a bit".

The group members news.com.au spoke to said Evans had been seeing Tostee since at least April, when she visited him on the Gold Coast.

Evans deleted her Facebook profile soon after news broke on Monday of the posts she made.

Evans supported Tostee and his family during the last days of his trial.

On Monday, it emerged that during the trial, Evans defended Tostee on social media, claiming Tostee was no different to other guys.

She also attacked Wright as a "phycho" [sic] drunk.

"He was only behaving how every other guy on the gc [Gold Coast] seems too but gets strung out for it," Evans wrote on Facebook, in a post that has since been deleted.

"He's so far from this person described it's not even funny," she wrote in another, describing him as "very strong willed", "strong in character" and "determined".

In another, she said Wright, was "incredibly intoxicated" when she fell to her death from the balcony of his 14th-floor apartment while trying to climb to the balcony below in the early hours of August 8, 2014.

She described her as a "self confessed 'phycho' [sic] drunk whom felt it ok to assault people without warning on their own home".

"She acted irrationally and yet you continue to point the finger at an innocent man who acted in self defense [sic]."

In another post defending her partner, she described him as highly intelligent, and said he planned to sue media organisations for defamation.

"He's very strong in character and personality his legal team have now a solid defamation case and building at the ready," she said.

"The media has written blatant lies at times and they have a whole archive. He's probably going to make a lot out of it actually."

In private messages with the two group members, Evans also indicated Tostee was desperate to clear his name, and that he was suicidal as the proceedings continued.

Evans' identity was revealed after she posted a video on 30-year-old Tostee on social media app Snapchat, where he is seen reading a news article about himself.

In the video, which appears to have been uploaded over the weekend after a caption read "Lazy Saturday night", the user, Liz Evans, claims, "all Gable ever does is read about himself".

"I'm not up myself or anything," he replies.

Last week, Tostee was acquitted of the murder and manslaughter of his Tinder date, Warriena Wright.

Gasps were heard in the back of the courtroom where Tostee's family was sitting as the jury delivered their not guilty verdict about 3.20pm local time on Thursday.

Tostee himself appeared to show little emotion.

In a brief statement to media, Tostee's solicitor Nick Dore said Tostee was looking forward to putting the matter behind him.

"He's looking forward to moving on with his life," he said.

"He thanks those people who have supported him through this and realises just how tragic this has been for many people.

"At this stage he is looking forward to putting it behind him and considering his future from here."

Tostee declined to comment at the time.

In a lengthy, articulate post entitled, "regarding the balcony tragedy" he wrote on December 10, 2014, Tostee gave, for the first time, his version of what happened inside the apartment the night Wright, 26, died.

The contents of the 2-year-old post could not be reported until after the jury returned its verdict.

"I think it's time I spoke out about the events that have happened over the last few months," he wrote.

"Those aware will know I am referring to the tragic death of Warriena Wright.

"So far I've been silent about the whole thing which has left my hands tied while so many misconceptions and untruths are being circulated in the media and in the public.

"This has been extraordinarily difficult, and I have grown to believe my silence may have done more harm than good.

"So now you can hear it from me.

"First off let me say that the death of Warriena was the most tragic and distressing event I have ever experienced.

"Knowing I was the last person to be with her, it has left me permanently scarred and not a day passes that I don't wish I could go back in time and prevent it.

"For at least a week after it happened I was so overwhelmed I was unable to laugh or even crack a smile.

"I broke down in tears several times a day, or whenever I saw her picture in the news.

"I never expected I would ever experience something like this, nor did I have any idea how much it would affect me.

"Even though I had only known her for a night I was horrified that this had happened to her. I would never wish for it to happen to anybody.

"While I have not had the chance to meet or speak to Warriena's family, it pains me to think of the loss and suffering they must be experiencing."
