The government has been urged to repatriate the remains of all Thai nationals buried on the remote Indonesian island of Benjina.
Chairat Ratchapaksi, a former fisherman who was tricked into working on fishing boats off of Benjina, said he witnessed the deaths of Thai and Myanmar crew members.
He said he worked with others to bury the bodies of three Thais and a Myanmar national on the island.
Their deaths were a result of falling off the boat or seasickness, he said.
"When they died, their bodies were abandoned," said Mr Chairat. "The government should bring them home or at least conduct religious rites and erect statues for them."
The calls were made on Thursday after the remains of another Thai fisherman were about to be returned.
Representatives from the Labour Rights Promotion Network Foundation (LPN), Foreign Ministry, Labour Ministry, Royal Thai Police as well as Indonesian authorities on Thursday morning attended the cremation ceremony of the fisherman, Somkiat Srimuangkho, whose remains were earlier found buried on the island.
The ceremony was also attended by Somkiat's older sister Suksan Srimunagkho and Phra Ajarn Prasan Thongchai from Wat Buddha Metta in Jakarta.
Ms Suksan said she would bring the remains of her brother to her home province of Surin, where a merit-making ceremony will be conducted for him.
"He would be happy to be back home. His daughter is still waiting for his return although she knows her father has passed away," said Ms Suksan. "I want the government to bring home the remains of every person who met the same fate as Somkiat while working on the island."
Phra Ajarn Prasan, who is an assistant Buddhist missionary in Indonesia, said a Thai man sought food from his temple in Jakarta. The man said he had escaped from a Thai fishing boat off Batam Island.
The person said he was lured into working on the boat, where he had to work extremely hard and faced physical abuse from other crew members, so he decided to jump off the vessel and swam to the island, according to the monk.
