Passengers are required to fill out a form stating where they'll be during the mandatory 14 day quarantine.
Fewer than 6 in 10 people arriving into the country are answering calls to check they're self-isolating, it has emerged.
Passengers are required to fill out a form to say where they will be staying during their mandatory 14 day quarantine.
Over 45 and a half thousand Passenger Locator Forms were filled out between May 28th and June 30th.
Some people were exempt from follow up calls because they were travelling onto Northern Ireland or staying in the state for less than 2 days.
In Dublin Airport alone, 21,455 calls to check people were self-isolating were made 2 days after they arrived. Just 13,192 people or 61 per cent answered the phone.
When a second call was made 12 days after arrival, just over half answered.
Eoghan O'Mara Walsh, CEO of Irish Tourism Industry Confederation, thinks the quarantine rule is ineffective.
''I think there's other ways of making sure public health concerns are addressed in terms of testing and tracing and so on, that could be deployed more effectively, he said.
''And that would allow tourism to resume''.
Less than half of people arriving into the country through Dublin Port answered the check up call, while the response was better in Roslare Port, where 54 per cent of people took the call.
