LOL.. this is the ultimate irony. Singapore is one of the oldest associates. They became a member of the International Cricket Council in 1974. And also they were one of the founding members of Asian Cricket Council. On the other hand, Indonesia became an ICC member only in 2001 and their associate membership was confirmed in 2017. And despite this, Indonesia with their native players have been making rapid growth in cricket. And look at the margin of victory. Singapore all out for 50, and Indonesia chasing the target with more than half the overs to spare.
I do not think being an old or new member of the International Cricket Council makes any impact on your performance. In fact, the new associates are more professional and energetic to show better performances. You can see the pathetic performances of Pakistan, Bangladesh, Srilanka and Zimbabwe (men's) teams and teams like Afghanistan, the United States etc showing better and more impressive performances.
It was a pathetic performance by the Singapore Women as they were all out at 50 runs. None of the batsmen could enter into the double figures. Indonesian women chased this score with ease. Ni Putu Ayu Nanda Sakarini 25 runs and Ni Luh Dewi 18 runs sealed the game for them.
