The Thai contingent arrived home from Buenos Aires on Saturday after having their most successful campaign at the Youth Olympic Games.
Thailand finished 11th overall at the third edition with five gold, five silver and two bronze medals.
A Youth Olympic champion gets two million baht in bonus from the National Sports Development Fund, a silver medallist one million baht and a bronze winner 500,000 baht.
The Thai champions are boxers Atichai Phoemsap and Panpatchara Somnuek, taekwondo fighter Kanthida Saengsin, weightlifter Supatchanin Khamhaeng, and golfers Atthaya Thitikul and Vanchai Luangnitikul in the mixed team event.
Boxing was Thailand's most successful sport in Argentina's capital as all five fighters secured podium finishes.
Porntip Buapa and Sarawut Sukthet took silver medals, while Weerapon Jongjoho received a bronze.
The success will provide a huge boost for the Thailand Boxing Association (TBA) after its boxers' poor results in international tournaments.
The Thai boxing team failed to win a single gold medal at the 2018 Asian Games and returned empty-handed from the 2016 Olympics.
TBA bosses said yesterday the boxers had a bright future.
"It's a big achievement," said TBA president Pichai Chunhavajira, who welcomed the team at Suvarnabhumi airport.
"We have been trying to produce new boxers to replace the veterans."
He said Aitichai, in the 60kg division, may be capable of fighting at the 2020 Tokyo Olympics.
"He has a bright future but need more experience," Pichai said.
Golfer Atthaya said: "I am glad that we won gold. It's an honour to play for the country."
Atthaya, 15, is already a star on the international stage.
Arguably the best female amateur golfer in the world at the moment, Atthaya began her rise rapidly last year.
At the age of 14 years, four months and 19 days, she claimed the 2017 Ladies European Thailand Championship in Pattaya to become the youngest ever golfer to win a professional event.
A few weeks later, the Ratchaburi native captured two gold medals at the SEA Games.
This year, she won the inaugural Women's Amateur Asia-Pacific in Singapore in February.
With the win, she earned berths at the ANA Inspiration and the British Women's Open, and she took the low amateur honours at the two major championships.
The success in Argentina is a perfect tonic for Atthaya who failed to deliver at the Asian Games in August.
