This chapter presents observations from the Audit for the four infrastructure sectors - transport, water, energy and communications - across the NT. It provides data on the territory's population and economy (i.e. the key drivers of demand for infrastructure), and the value-add attributable to NT infrastructure, in 2011. It also outlines growth projections to 2031 for the territory's population and economy, and for each of the infrastructure sectors. As noted in the Introduction to this report, these projections are based on economic and demographic analysis set out in two associated studies.519
The Audit uses the Direct Economic Contribution (DEC) methodology to quantify both the value-add attributable to infrastructure in 2011, and the projected change in demand for infrastructure from 2011 to 2031. When considered in the light of other factors, such as capacity limitations which might constrain economic growth, this assists in the identification of locations and sectors that are likely to warrant further attention in the Australian Infrastructure Plan.
This chapter also takes account of other documents, including plans, studies and strategies, prepared by the NT Government and others.
