But a public health expert has warned the two countries first need to get on the same page about what elimination of Covid-19 actually means.
Epidemiologist Professor Michael Baker says a travel bubble would need safeguards like rapid contact tracing, mass masking in places like airports - and even a shared definition of the word elimination.
