my point is that if you can study in non EU countries then I see no reason why you can't study in EU countries if we are no longer an EU country
Erasmus provides a student grant.
Australian fees for international students are around £ 9,000- £19,000 for a bachelor's. Did he go with Erasmus Mundus? A Commonwealth supported place? Another scholarship?
You say he saved up for years. That's rather the point. Erasmus allows students to experience education abroad without that.
am not too pleased at the idea that UK students should be able to study in other EU countries and not pay just like the local students. That sounds to me like taking advantage of that countries' benefit system just as many of us would object to EU residents coming here to take advantage of our system.
They do pay the fees like the local students, that's the point. As uni fees are substantially less than here in other EU countries, that's a huge benefit.
In France, to qualify for benefits you need to have made social security contributions for a minimum of 4 months during the previous 28. Students have to register their European healthcare card, to to qualify for healthcare.
