Alongside the 56th Putra Cup, three other regional golf tournaments - the Lion City Cup, the Santi Cup and the Kartini Cup - will be played concurrently at the Tanah Merah Country Club's Garden Course over the next four days.
This is the first time all four competitions will be played in the same week in Singapore.
Said Lee Lian Hong, the South-east Asian Amateur Golf Team Championship organising committee chairman: "By arranging all four tournaments in this format, the senior and junior golfers will have the opportunity to see one another in action.
"The up-and-coming golfers can learn from the elder players and this adds more to their experience. The juniors will be up there one day and this is a good platform to develop their potential."
The Singapore Golf Association executive board member added: "It also (gives) our neighbouring countries a viable field of competition where they can bring in their pool of golfers to test themselves on the regional stage."
With the tournaments bringing together 90 amateur golfers from the region, Thailand will defend their Putra Cup (men's tournament), Lion City Cup (Under-16 men's) and Santi Cup (women's) team titles. The Philippines will look to retain the Kartini Cup (U-16 women's).
Singapore will field Louis Tee, Tommy Tan and Ryan Wong (Lion City Cup); Amanda Tan, Jacqueline Young and Callista Chen (Santi Cup); and Nicole Mok, Denise Wong and Vanessa Khoo (Kartini Cup).
