In 2011, the DEC of infrastructure in NSW was $60 billion, which was 32.3 per cent of the national figure. By 2031, NSW infrastructure DEC is projected to increase by around $47 billion, or 78 per cent, to $108 billion. This would represent 29 per cent of national DEC. Figure 48 and Figure 49 highlight the spread of infrastructure's economic contribution across the 14 Audit regions in NSW for 2011 and 2031 respectively. Consistent with population growth, DEC growth is projected to be greatest in the Sydney region, increasing by 85 per cent from $43 billion to $80 billion during the period from 2011 to 2031.

Table 33 provides a snapshot of NSW economic infrastructure across the four sectors of transport, water, energy and telecommunications. The table notes the capacity of each subsector in general terms and its rate of utilisation in 2011, along with historical (2011) and projected (2031) DEC for each subsector.
