Passengers arriving from some EU countries won't have to quarantine from Sunday, if they can prove they've tested negative for Covid-19 in the three days before they travelled.
A plan to test passengers at airports is being prioritised to support the new traffic light system, which comes into effect on Sunday.
Passengers arriving from countries branded orange won't have to quarantine if they can prove they've tested negative within the three days prior to arrival.
Red passengers still have to restrict their movements for two weeks, but plans to bring in testing at airports will see this eased.
Transport Minister Eamon Ryan says these passengers would be tested 5 days after landing, but this won't be available for a number of weeks.
Last year was Dublin airport's busiest ever festive season, with 1.2 million people passing through.
The Transport Minister says it makes sense for people living abroad to avoid coming home this Christmas.
Dublin airport have approached up to 20 different testing providers and are said to be ready to set up a facility quickly once given the green light.
