''Don't mess with our internet'' has been the resounding message on social media since opposition communications spokesman Malcolm Turnbull announced the Coalition's alternative national broadband network policy.

A new Twitter hashtag – ''fraudband'' – is being used to aggregate mockery of the Coalition's NBN. By Wednesday morning a new ''fraudband'' message was appearing on Twitter every minute.

The Coalition's alternative NBN will be completed two years sooner than Labor's and would cost an estimated $17 billion less but it relies on inferior (slower) copper telephone lines. Labor's network runs fibre all the way to the home for 93 per cent of Australians.
