A Deloitte Access Economics analysis for the government found the average household would get $3800 in benefits a year by 2020 through using the NBN, through savings in communications, e-commerce, online entertainment services, travel savings, employment by teleworkers and productivity.
"Added together, these estimates suggest very significant household benefits from broadband," the report said. The research didn't account for the cost of implementation or equipment like modems and computers, and didn't specify exactly how fast the broadband would need to be for such benefits to be achieved.
"Many of the benefits will emerge gradually, as consumers find price discounts and variety online, as more employees are allowed to telework, and as people get more accustomed to accessing services online," the report said.
"There will be a lot of change from the broadband revolution and there will be a gradual transition this decade."
AAP is reporting the opposition's communications spokesman Malcolm Turnbull said today that the report doesn't compare Labor and Liberal policies, and instead praises fast broadband more broadly.
"It's not an argument in favour of fibre-to-the-premises, it's an argument in favour of everyone having very fast broadband, and I agree with that," Turnbull was quoted as saying.
"But they should have it now. The way Labor is going it will take decades.
"The speeds Deloitte are referring to here are all available under our approach."
"The NBN will drive innovation, we know it makes economic sense ... we need to do it right, do it once and do it with broadband - the coalition's plan relies on last century's technology," he told reporters in Melbourne.
"The NBN is an essential service that is just as important in the 21st century as water and energy."
A previous Deloitte Access Economics report found NBN-enabled telework may create 25,000 additional jobs in fulltime equivalent terms by 2020-21, with around 10,000 of these created in regional Australia.
The NBN would also be expected to create up to 18,000 construction jobs at the peak of its rollout (around 13,000 in FTE terms), and through telework, the NBN would create twice many jobs – on an ongoing basis – with this significant structural change to the labour market resulting in an increase in labour force participation.
