This paper focuses on the socio-spatial patterns of the National Broadband Network (NBN) that using a mixed-technology platform is being rollout across the Australia. One of the vexing aspects of the mixed- technology NBN is the lack of data transparency which has drastically limited the ability of evidence-based telecommunication policy analysis.
The purpose of this paper is to leverage basic data mining techniques, combined with census-based socio-spatial data (SEIFA), to uncover the geographic intricacies of the NBN at the metropolitan regions of Sydney and Melbourne. The findings in terms of the dominance of some of the inferior technological options (e.g. HFC) across the two major metropolitan regions, are quite shocking. The paper concludes with a discussion of equity implications, and calls for telecommunication infrastructure to be accounted for in the future strategic planning.
