Australians have turned on the NBN as inadequate and inferior to Labor's model in today's Essential Report poll, with even Liberal voters dismissing it.

With NBN Co embarrassed by its admission that the Optus cable network was inadequate for its use -- a serious blow to Malcolm Turnbull's claim to be able to deliver the NBN faster and more cheaply than Labor -- just 22% of voters believe the NBN will be adequate for Australia's future internet needs, while 47% believe it won't be. And partisanship has little impact on voters' views: 44% of Coalition voters think it's inadequate compared to 47% of Labor voters, 65% of Greens voters and 56% of "other" voters. Men are more definite in their views, splitting 51%-26% compared to 43%-19% among women, of whom 38% say they don't know.
