Anyone arriving in the Republic from overseas needs to provide proof of a negative Covid test.
For the fully vaccinated, only a professionally administered antigen carried out no more than 48 hours before arrival or a PCR test within 72 hours of arrival, will be accepted.
A passenger locator form must also be completed before departure, in line with rules put in place previously.
Simon Palmer, communications manager for Stena Line, says he hopes these new rules wont put people off travelling home to Ireland for Christmas:
"Because this is obviously one of the busiest times of the year for us. And where bookings are high, so hopefully won't put people off too much. It is feeling a bit like déjà vu in terms of the new restrictions and hopefully, you know, these measures are temporary and they won't be in too long so fingers crossed, we can get back to normal as soon as possible."
