Thai officials say a young Saudi woman holed up in a Bangkok hotel room seeking asylum in Australia will not be forced by them to return home.

Rahaf Mohammed Mutlaq Alqunun, 18, claims she was abducted on Sunday and Saudi Arabian diplomatic staff confiscated her passport on arrival at Bangkok's Suvarnabhumi airport.

She subsequently appealed for help from Australia, Canada, the United States, Britain and other European nations.

"Please I need u all. I'm shouting out for help of humanity," she tweeted.

Ms Alqunun said she was being held at an airport hotel by diplomatic and airline staff, despite having a visa to travel to Australia.

She wrote of being in "real danger" if forced to return to her family under pressure from Saudi authorities and has claimed she could be killed.

The teenager vowed to not leave her hotel room until she spoke with the United Nations High Commissioner for Refugees.

Thailand's chief of immigration police Major General Surachate Hakparn told reporters Ms Alqunun's father was expected to arrive in Bangkok on Monday night, however she would not be sent anywhere against her wishes.

General Surachate said he would also meet with UN officials himself to discuss her asylum plans.

The UNHCR had earlier on Monday issued a statement saying it was following the case and "trying to seek access from the Thai authorities" to meet with Ms Alqunun to assess her need for international protection.

Labor's foreign affairs spokeswoman Penny Wong said she was concerned by the reports over the situation and had sought further information from the government.

"It is a very distressing position she is in," Senator Wong said.

Immigration Minister David Coleman declined to comment.

Germany's ambassador to Thailand, Georg Schmidt, posted a message of concern on Twitter, which he said he was conveying to Thai authorities.

Ms Alqunun said she had been abused by her family and would be killed if she returned home. She posted her passport details on Twitter to confirm her identity.

Saudi Arabian authorities have denied their involvement, saying Thai officials stopped Ms Alqunun because she did not have a return ticket or itinerary to show she was a tourist.

"She will be deported to the state of Kuwait where her family live," the Saudi Embassy said in a statement.

"The embassy does not have the authority to stop her at the airport or anywhere else."

Saudi women are subject to strict male guardianship laws and must obtain consent from a male relative for travel documents.

Ms Alqunun told a Thai human rights worker her family kept her in her room for six months because she cut her hair.

She had asserted her independence and renounced Islam but had been forced to pray, wear a hijab and was beaten by her brother.

Ms Alqunun is understood to have fled from her family two days ago during a trip to Kuwait.
