Da Silva returned to Singapore in 1912. From 1926 to 1935, he served on the
Education Board. He was appointed a member in place of

During a speech made at the Singapore Recreation Club in November 1934, he stated: "We must give up the idea that the Eurasian is privileged. He is not, and the sooner he gets that idea out of his head the better. They cannot succeed unless they put their shoulders to the wheel." He was also a supporter of the
Eurasian Women's Association. On 2 February 1940, he was a guest on
The War From Various Viewpoints, a radio series broadcast on the
