Katter said the NBN is 'a great thing for this country'. Windsor said the NBN is 'too good an opportunity to miss'. Family First Party leader Steve Fielding said the NBN will 'bring [Australia] up to speed'. The size of the government's investment was a key point of debate. The Coalition called for a cost-benefit analysis, describing the NBN as 'a white elephant on a massive scale'. The Economist Intelligence Unit (EIU) criticised the NBN as a 'huge cost to the public sector', instead advocating a policy focused on filling 'gaps'. The Greens said the NBN 'is a key piece of 21st century infrastructure'. Telecommunication companies Optus, iiNet, Internode and Vodafone-Hutchison expressed support for the project, along with the Australian Internet Industry Association, which said optical fibre solutions are 'a critical part in the evolution of the internet'. Internode managing director Simon Hackett said he was 'glad [the NBN is] going to go ahead'. Vodafone-Hutchison CEO Nigel Dews said the NBN will 'transform the competitive landscape'. However, other telecommunications companies including AAPT, PIPE Networks and Exetel have expressed opposition to the NBN. AAPT chief executive Paul A. Broad said the NBN will 'stifle competition'. PIPE Networks founder Bevan Slattery said the NBN is 'economically irresponsible'. Exetel chief executive John Linton described the NBN as a 'political stunt'. Microsoft, Google and Intel expressed support. Google's head of engineering, Alan Noble, said the NBN will 'be the greatest enabler of innovation'. Intel managing director Philip Cronin said 'the NBN has the potential to deliver significant long term benefits'. The Swinburne University of Technology conducted a survey of Australian Internet usage for the World Internet Project between and . The survey of 1,000 people asked about Internet usage and how it influences daily life. A question was included asking if the NBN was a 'good idea'; 74.5 per cent agreed. In the survey, the NBN had stronger support among younger people and Internet users. Given the market failure found in attempting to develop and implement the replacement telecommunications network a natural monopoly was set up with ACCC safeguarding the interests of end users, access seekers and NBN Co. This is achieved through NBN Co entering into a Special Access Undertaking to govern aspects of NBN design, service and charging until 2040, agreed 2013. Some NBN areas are 'brownfield' that were provided directly by NBN Co, but many were new 'greenfield' areas in subdivisions that did not have an existing service.
