Hi Phillip,
For more information on traveling to the Republic of Ireland, I'd suggest you check
the latest information on travel restrictions to Ireland before you travel back, to make sure you have the most up-to-date information.
You'll have to fill out a
Passenger Locator Form and, as of December 5, provide evidence of a negative result of an antigen or RT-PCR test, depending on your vaccination status.
I hope this helps!
Antoine
