Entry restrictions depend on which country you’re travelling from and whether you’re vaccinated against COVID-19, previously infected or neither. You must show proof of a negative COVID-19 test before entry. Testing and isolation requirements can change at short notice, with additional requirements for travellers from high-risk COVID-19 countries. A ‘corona passport’ is required to enter some venues. Denmark accepts Australia’s international COVID-19 vaccination certificate, the EU COVID Certificate, and other certificates that meet the rules to get a ‘corona passport’.
