For anyone considering to still fly to their home countries or back to Australia via Singapore, please be advised that Singapore is no longer allowing Short term travellers or transit via Changi Airport.
I have a mate (Australian Citizen) of mine who is currently in India, who is possibly locked out of the Australia if Malaysia & Thailand close their transit options as well.
Singapore Airlines have grounded 96% of their flights with only 7 flights still active.
Stay put and stay safe everyone.
If i was your mate i would be getting in touch with the Aus Embassy as they are pretty much the only ones who can arrange to get anyone home atm
