AUSTRALIANS will access the National Broadband Network for as little as $50 a month, according to the latest telco to reveal its NBN packages.

In the best indication yet of what most Australians will pay for super-fast internet, iiNet announced its premium packages - including speeds of 100 Mbs and 1 terabyte of data - would cost just $100 a month.

That's about $90 less than Internode's premium service revealed earlier this year.

iiNet is the country's third-largest internet service provider behind Optus and Telstra which are yet to reveal their NBN prices.

iiNet customers will pay $49.95 a month for a 40GB data quota and maximum speeds of 12 Mbps. The 200GB plans will cost $59.95 at the same speed and customers will have to pay an extra $5 a month to increase speeds of both packages to 25 Mbps. Fifty Mbps will cost an extra $15 and 100Mbps an extra $20.
