"[Ms] Rahaf is not a political asylum case", he insisted. He remains in custody at the Bangkok Remand Prison.
Ms Alqunun will be subject to Australian security and character checks as the government examines her suitability for refugee settlement. After she was detained by the Thai authorities, the Saudi teen barricaded herself in a hotel room, evaded deportation and wielded social media to publicize her fears that her life was in danger.
Ms Alqunun is now in the care of United Nations officials who say it will take about five days to process her request for assistance after she said she feared her family would kill her if she were sent home.
Surachate added that Ms Alqunun's father would remain in Thailand, under the care of the Saudi Arabian embassy, until it is clear where she will receive asylum.
As public pressure heightened, an Australian minister appeared to go beyond Canberra's initial bureaucratic promise to consider her case if and when United Nations experts judge her fear of mistreatment justified.
Saudi Arabia's embassy in Thailand denied reports that Riyadh had requested her extradition.
Saudi teenager Rahaf Alqunun's first reaction to the news Australia might resettle her was disbelief, then emojis.
Since Saturday Ms al-Qunun has been tweeting about her circumstance, with her case highlighting the issue of women's rights in Saudi Arabia. The 18-year-old Saudi Arabian woman is hoping to seek asylum overseas and barricaded herself inside a hotel in Bangkok to prevent being expelled by Thai authorities.

On Sunday, Thai immigration chief Surachate Hakparn made a statement that Qunun was denied entry because of her lack of documents.
"When she arrived, she open a new (Twitter) account and her followers grew to 45,000 in one day", he said in Arabic. Public pressure prompted Thai officials to return her passport and let her temporarily stay in Thailand. The father said he wants his daughter back but respects her decision.
WATCH: A UNHCR representative visited the transit hotel at Suvarnabhumi airport on Monday where Saudi national Rahaf Mohammed Alqunun has barricaded herself inside a hotel room with a table and a mattress.
She later tweeted she felt safe under United Nations protection and her passport had been returned. She claimed that a Saudi diplomat seized her passport with plans to forcibly send her home. However, in repeated statements, the Saudi embassy in Bangkok said it was only monitoring her situation. Saudi activists say the kingdom, through its embassies overseas, has at times put pressure on border patrol agents in foreign countries to deport the women back to Saudi Arabia.
"The decision to meet with the family is ultimately Ms. Al Qunun's and the responsibility for her safety and physical protection lies with the Thai authorities", UNHCR spokesperson Babar Baloch told NPR.
Ultra-conservative Saudi Arabia has come under fire since the murder of journalist Jamal Khashoggi in the country's consulate in Istanbul previous year. Khashoggi, who wrote critically of Crown Prince Mohammed bin Salman in columns for The Washington Post, had been living in self-imposed exile before Saudi agents killed and dismembered him inside the Saudi Consulate in Istanbul.
