Australian universities have been warned against relying too heavily on any particular group of students to keep their coffers full.

Education Minister Dan Tehan has expressed the sentiment, after one of his colleagues said he believes some universities are too dependent on international students for their livelihood.

"I don't think that we have to be too concerned about the fact that we do have foreign students coming to Australia, participating in our higher education sector," Mr Tehan told Sky News on Sunday.

"They bring a diversity to student life on our campuses.

"What we do have to ensure though, is to make sure that universities understand that the more diverse the student mix they have, the better secure their financial forecasts will be, so the more diversity they can get, into their student mix, the better."
