I mean beyond Portugal and Iceland the list is basically pointless.
Australia and New Zealand don’t even want to let their own citizens in. Singapore has 21 day quarantine. Brunei has 14 day quarantine. St Helena can only be reached via a red list country. The Faroe Islands can basically on be reached via a Amber list country. Tristan da Cunha was basically unreachable at the best of times.
I hear the South Sandwich Islands are lovely at this time of year.
