The country has announced a team of 569 athletes who will compete in 35 sports in Malaysia's capital Kuala Lumpur.

This will be their biggest team for any event outside of Singapore, with action taking place between August 19 and 30.

In addition, Singapore will send 94 athletes to compete in 11 sports at the Asian Para Games (APG), also being held in Kuala Lumpur between September 17 and 23.

At the flag ceremony, shooter Jasmine Ser and long jumper Suhairi Suhani were confirmed by SNOC as the flag bearers for the SEA Games and APG respectively. 

SNOC President Tan Chuan-Jin and Grace Fu, the Minister for Culture, Community and Youth, first presented the flags to the team's Chef de Missions who then passed them to the athletes.

Ser, who won team gold in the 10 metres air rifle event at the 2015 SEA Games on home soil, will be competing at the event for a sixth time. 

She is also a triple Commonwealth Games champion.

"It’s a great honour to represent Singapore and an even greater one to be selected as the flag bearer," said Ser.

"I have always watched the opening ceremonies and even attended some, but I have never thought that I would be chosen as a flag bearer.

"I am excited and I hope Singaporeans will support us at the Games."

Following the flag ceremony, around 2,000 people joined in with Olympic Day celebrations.

They marched a five kilometre route to the Marina Bay area and back.
