THE national broadband network may have secured the support of the independents and squeezed through Parliament but according to the next generation of internet users it's a waste of money.

Diamond Valley College, in Melbourne's north-east, was one of only two schools in Australia that made a submission to the federal inquiry into the role of the NBN.

The school surveyed 380 of its students and found they were prodigious internet users, with 99.5 per cent of them on Facebook. But year 11 student Alex Klammer believes the $35.9 billion broadband network is a waste of money.

''The … government wants to speed up the internet but it's going to slow it down with all these firewalls and proxies to stop you getting on to certain websites,'' Alex said. ''It doesn't seem as if it would work.''
