This chapter presents observations from the Audit for the four infrastructure sectors - transport, energy, communications and water - across Tasmania. It provides data about the state's population and economy (i.e. the key drivers of demand for infrastructure), and the value-add attributable to Tasmanian infrastructure, in 2011. It also outlines growth projections to 2031 for the state'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.465
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 overall 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 approach helps to identify locations and sectors that are likely to warrant further attention in the Australian Infrastructure Plan (the Plan).
This chapter also takes account of other documents, including plans, studies and strategies, prepared by the Tasmanian Government and others.
