Instead, she was given back her passport and allowed to enter Thailand temporarily under the protection of the United Nations refugee agency, which was expected to take about five to seven days to study her case and her claim for asylum.
A United Nations spokesperson told NPR that the refugee agency has had no contact with either family member but that the father and son are communicating with Thai authorities to try to meet with Alqunun.
The first message from Ms Rahaf Mohammed al-Qunun, in Arabic, was posted at 3.20am Thai time from the transit area of Bangkok's Suvarnabhumi Airport. "I want asylum", she said. He said it was "too early to tell" if she will be granted asylum or refugee status.
Al-Qunun's supporters believe her visa to Australia may have been cancelled as she reportedly found she was unable to log into her Australian government immigration profile. She also gave access to her social media account to her friend Noura, who also fled Saudi Arabia because she renounced Islam.
Within 36 hours it prompted Thailand's government to reverse a decision to force the young woman onto a plane that would return her to her family.
The agency said in a statement that it required five days to process the girl's request.
The Australian Government says it is monitoring the case closely."The claims made by Ms Al-Qunun that she may be harmed if returned to Saudi Arabia are deeply concerning".
Meanwhile, Human Rights Watch called on the Australian government to allow Alqunun's entry into that country. If the agency refers someone, "Canada selects foreign nationals for resettlement who have no reasonable prospect of finding another durable solution", she added.
"When it became clear that she wasn't going to leave, I decided it was important to stay and have someone documenting what was going on", Ms McNeill said.More news: Jets Interview Kliff Kingsbury For Head Coaching Job

For more than 24 hours she fed global media, rights campaigners and a concerned public a stream of dramatic videos and descriptions of her ordeal.
In 2017, another Saudi Arabian woman, Dina Ali Lasloom, who also tried to claim asylum in Australia via Kuwait, was apprehended in the Manila airport and sent back after begging for help through a stranger's twitter account because she believed her family would kill her.
Under what is known as the "male guardianship system", a woman's father, brother, husband or son has the authority to make critical decisions on her behalf.
A young Saudi woman is asking for Canada's help after tweets about her efforts to flee abuse and seek asylum overseas put her in the global spotlight.
Gen. Surachate Hakparn said that Alqunun's father and brother arrived together in Bangkok on Tuesday but Alqunun refused to meet them.
The Thai immigration chief said on Monday the embassy had alerted Thai authorities to the case, and said that the woman had run away from her parents and they feared for her safety.
After being informed by immigration that she would be placed on a flight back to Kuwait, the young woman barricaded herself in her airport hotel room and began launching a barrage of appeals to the Twittersphere.
From her makeshift bunker, Qanun insisted her case was an urgent asylum matter and her tweets garnered the attention of prominent activists, human rights groups and Bangkok-based diplomats, with the German ambassador voicing his concern to Thai authorities.
