Hey Cyberphysio!
I find your question very odd. I think it is worth studying anywhere in the world as long as it is from a RECOGNISED, ACCREDITED university. There are many masters courses being offered in places like India, South Africa, Malaysia that are widely accepted anywhere in the world. You should just do a proper check on the uni and apply. As i have noticed, on comparing the study curriculum of Ireland and Uk, they are very alike. So, i dont think there would be much doubt in the type of study you will get in Ireland.
Unless ofcoarse somebody else has another view!!!!!

Yours,
Aisha.
