5.3 Summary of South Australia infrastructure from 2011 to 2031

In 2011 the DEC of infrastructure in SA was $14 billion, which was seven per cent of the national figure. Figure 89 shows SA DEC for 2011 in the context of the four regions identified for the Audit (the Audit regions).

By 2031, SA infrastructure DEC is projected to increase by around $10 billion, or 71 per cent, to $23 billion. This would represent six per cent of the national DEC. Figure 90 shows projected SA DEC by Audit region in 2031.

Growth in the DEC of SA infrastructure is projected to be fastest in the greater Adelaide region, where it is projected to grow by 74 per cent from $12 billion to $21 billion over the 2011-31 period.

Table 71 provides a snapshot of SA 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.
