I think as Australia managed the Coronavirus very well, we cannot afford another outbreak that is caused either inside or outside of the country.
I would support for closure of international borders, and even if we are establishing travel bubbles, they should come into Australia in a safe way, including:
- Quota based, Australian first system for bubble countries
- No mixing between bubble passengers and others, i.e. flights from Singapore to Australia under the bubble should be Singaporeans only
- Testing on arrival and pre-departure to ensure no asymptomic passengers on board and into the country.
I think other than Singapore, South Korea, Taiwan, Japan, Hong Kong, Vietnam and Thailand should be in consideration of opening by Christmas too.
