Australia is now a nation of "iFamilies" with an insatiable appetite for online content, according to NBN chief customer officer, John Simon.
The Australian Bureau of Statistics reports the average fixed-line end-user broadband usage has increased by 46 per cent in the past year.
Average broadband downloads grew from 36 GB per month in June 2013 to 51.7 GB per month in June 2014.
NBN Co's network traffic report also shows growth in heavy internet usage with the average total data consumption per end-user on the NBN now at 77 GB per month.
This includes both 61 GB download and 16 GB download and 16 GB upload usage.
Simon said the NBN would provide a fast and reliable broadband network to help ease the impending data tsunami brought on by the rapid growth in our internet usage.
"Australia is now a nation of iFamilies with an insatiable appetite for online content," he said.
"Our network trends show the improved speed and reliability of the NBN unlocks more value for consumers and small business.
"With access to services of the NBN, a household could have people simultaneously uploading videos of family and friends to social networking sites, downloading on-demand entertainment, while still working from home using Cloud computing and multiline high-definition video collaboration applications."
