About 16,600 more businesses and homes in north Queensland will be able to connect to the national broadband network (NBN) within 12 months.

The coverage area includes a total of 12 suburbs in Cairns, Mackay and Townsville, federal Communications Minister Stephen Conroy said in a statement today.

"The NBN is also providing fast broadband at the same wholesale price everywhere in Australia, meaning people in Cairns, Mackay and Townsville will pay the same for NBN services as those living in Brisbane, Sydney and Melbourne," Senator Conroy said.

Under Labor's $37.4 billion NBN project, network builder NBN Co will deliver high-speed optic fibre broadband cable to 93 per cent of homes, schools and businesses by 2021.

About four per cent will be supplied by fixed wireless, while three per cent will receive broadband services by satellite.
