By the time everyone is vaccinated in overseas destinations and here at home,I think it is fair to assume there will not be significant International travel until start of 2022 at the earliest.With the exemption of a very small number of travel bubbles.
The Government is not going to risk a domestic consumer boom given no COVID cases.Shopping centres are packed.Restaurants full.
2021 will be closed off whilst until vaccinations take place.They have said late 2021 but I think start 2022 or mid 2022 is realistic.
