Several countries have implemented temporary travel restrictions on arrivals from India but the Australian announcement goes a bit too far. Australia is the only country that has even banned Australian Citizen and Residents. US and UK don’t just exempt their citizen and residents but also the international students.
The difference in the announcements has been clearly observed in the media.
I have shared my perspective in my interview with Navneet Anand of Voice Aajkal, a local channel if the Indian Australian community.
