Missing: Australian man Nathan Hansford, a long-time expatriate resident of Thailand.
Temporary memory loss sustained by Nathan Hansford following a motorbike accident has raised several unanswered questions regarding his disappearance.
Mr Hansford was found in a Phnom Penh hotel by family members on Sunday after the Australian businessman lost contact with his family, friends and colleagues more than a month ago.
He was last seen leaving his home in the gated suburb of Thungkru on January 31 to travel in a taxi to Mo Chit in central Bangkok. He had not been in contact with family or friends since Christmas.
Mr Hansford’s brother Hamish, who lives in Canberra, said Nathan's amnesia was restricting the family from discovering the circumstances of the accident and how he managed to survive in Cambodia since the incident.
“There were obviously a couple of people looking after him in Cambodia but whether they were hotel staff or not I am not sure at this stage,” he said.
“He is in significant pain as a result of the accident and hasn’t been able to get around as he usually does. He is gradually returning to health and is in and out of hospital receiving treatment.”
The Department of Foreign Affairs and Trade confirmed Mr Hansford’s reappearance on Monday morning, but offered little information on how he came to be in Cambodia.
"We confirm that Australian man, Nathan Hansford, reportedly missing in Thailand, has been located in Cambodia. Consular officials in Cambodia are in contact with Mr Hansford's family," said a spokesperson.
Hamish said it was “no surprise he was found in Cambodia given the scope of his work,” and said it was possible Nathan was working for clients in Cambodia at the time of his disappearance.
Mr Hansford, an international contractor specialising in public finance and capital market development, had lived in Bangkok for 10 years, and working in countries including Cambodia, East Timor and Iraq.
One of Nathan’s employers in Bangkok, Adam Smith International, said he was not conducting business on their behalf at the time of his disappearance.
“Nathan Hansford has worked with Adam Smith International but was not working for our company at the time he went off the radar,” said the spokesperson.
Another employer based in Bangkok, Asian Development Bank, said they had not heard from Mr Hansford since mid-December and had launched their own efforts to find him.
Hamish said the social media campaign spearheaded by Nathan’s sister-in-law Tara Cheyne played a key role in locating Nathan by uncovering leads and information valuable to his recovery.
Nathan’s sister, who flew to Bangkok to locate Nathan on March 4, said the family’s social media campaign had “saturated” Bangkok.
The family have expressed their gratitude to Australian and Thai authorities who assisted in locating Nathan, “especially the outstanding consular staff in the Department of Foreign Affairs and Trade – they are truly a national asset for those in trouble overseas.”
A senior spokesperson for the Thai Ministry of Foreign Affairs said the Royal Thai Police were aware of Nathan’s disappearance and the “authorities concerned had been working closely with the Australian Embassy in Bangkok.”
In addition, Australian-Thai Chamber of Commerce appealed for information regarding Mr Hansford’s whereabouts and posted his photograph on the internet.
The family are now requesting privacy "so that Nathan has the time and space to return to his full health and so that his family can concentrate on supporting him."
