From next Thursday it will be a criminal offence for anyone arriving into the country not to fill in a locator form spelling out where they'll be self-isolating.
Cabinet Ministers approved the decision this afternoon and there will be spot checks done to make sure people are isolating.
The penalties for non compliance will be a maximum 6 month jail term or a fine of 2,500 euro.
However, it won't apply to people coming into the country from Northern Ireland.
Health Minister Simon Harris says the health implications of Covid 19 are still being felt:

There's still people dying in our country every day from covid-19 and there's still many people getting sick in our country. No one wants to leave restrictions in place for a minute longer than is neccesary.''
The Government continues to advise Irish citizens and residents against all non-essential international travel, and passengers arriving into Ireland from overseas are asked to self-isolate for 14 days.
Minister Harris said: "We continue to advise everyone against non-essential travel. However, if a person does arrive into Ireland, they will legally obliged to fill out this form, regardless of their nationality.
“The Form will be used to facilitate a system of follow up checks to make sure people who travel to the country are staying where they said that they would. The Form will also ensure more accurate and quicker contact tracing, should we have a confirmed case on a flight or ferry coming into Ireland.
"Every measure we take is aimed at stopping the spread of Covid-19 and protecting people from this virus. This is no different."
