First it is new to me that currently there are foreign droms that are in quarantined .
Second did you see the list of infected Indians that came in, We have a 79 years, what type of jobs do you think he is here in Singapore for ?
We also have researchers and Indian Students that came in infected...many Singaporean Students that are studying in China Universities are not
allow to fly back in current pandemic condition, so why allow such things to happen when India is a high risk country ?
Bear in Mind Last year in Feb 2020 when Singapore had an outbreak The Indian Foreign Ministry issued a travel advisory against travelling to Singapore.
If India wants to be a world power , It must comes with responsibility , when Your country situation is out of control, you should not wait for
other countries to stop your citizen from flying all over the world thus spreading the virus...
Anyway You can search on Facebook someone have collated the data of all the Indians citizen or those that flow in from South Asia, you will
notice it is not as what you listed,,.. many short term visitors , dependant pass , students, researchers , etc
(here someone just posted on sammyboy too...

.( one case , I remembered was an Indian lady who flew here in Jan and tried to fly back in April, she was supposed to be a domestic maid, what type of maid that can afford to fly only after working for 3 months, mind you, when she was warded.. it was not in a Gov Hospital it was in Mount E a private hospital which supposedly are for the rich. Her employer must treat her very well which such medical benefits.
In current pandemic situation you don't expect major constructions to be going on... those that are cleaning the street etc are still the same
group of people , and a majority are not from India,,,more likely from Blangadesh... we exchanged morning greetings almost everyday...so
don't think you are right....
I am sure you have also read that Australia have banned her nationals who are in India from flying back and majority of them are of Indian origin.
The Australian of Indian origin have even suggested to their Gov to fly to Singapore first as a form of quarantine before flying back....!
