Heavily edited to hopefully avoid closing of my question.
How would a hypothetical adult female Singaporean Australian dual citizen travel directly to Singapore from Australia? Direct flights only.
Subsequent question: do you know people that got caught in Singapore due to the above, and what were the consequences? were they forced to give up a citizenship, is it on the spot, do you receive a letter, can you ignore it, etc?
Maybe Reddit is the better platform to ask for people's experiences and this stackexchange is for factual answers only
