Foreign students must spend a hell of a lot money in this country. My neck of the woods the biggest number of students coming in must be on the campuses at Canterbury, which is forever expanding and not all of it is onsite living, quite a few students rent properties off site, especially when you get the rich ones with their mates. They have to eat, use the nightlife, all of which is critical to our economy/hospitality. Probably part reason Canterbury still thrives as well as the tourists, then you have the private boarding schools around the country, who have travelled here from places such as Asia. I honestly couldn't think of any reason why anyone would have problems with students coming here, yeah you will always get people abuse the system but that's just every part of daily life. Certainly a positive to our economy.
