I am travelling from Melbourne (30th July) to Chennai(4th August) via singapore. Got a transit in singapore for 4 days. And have read that i could avail up to 96 hours of transit visa. But my stay exceeds to 100 hours (including time of departure). Was wondering if i still need to apply for a tourist visa because ill be at Changi Airport before the 96 hours end. Let me know. Thank you!
