Hong Kong is considering a "travel bubble" with Australia along with other countries including New Zealand and Singapore.
Anyone allowed to travel within the bubble would be required to undergo COVID-19 testing at both ends of their journey. A coronavirus test – that is mutually recognised – would need to be carried out before travelling, and another verification is needed after arrival in Hong Kong.
Hong Kong health authorities would then proceed to further discussion with potential countries.
Countries being considered for the bubble were from Asia, the Pacific and Europe where the pandemic is "under better control".
Whether travel bubbles can be established would depend on a host of factors, including the epidemic situation and its containment in respective places.
The timetable will be a matter of bilateral agreement between Hong Kong and partnering countries. It all depends on how ready and comfortable both parties are with the situation.
