In 2011, the DEC of infrastructure in Queensland was $36 billion, which was 19 per cent of the national figure. In 2031, Queensland infrastructure DEC is projected to increase by around $39 billion, or 107 per cent, reaching $74.6 billion (20 per cent of national DEC).
Figure 71 and Figure 72 highlight the spread of infrastructure's economic contribution across the Audit regions in Queensland for 2011 and 2031 respectively. DEC growth is expected to be fastest in South East Queensland and relatively high in Gladstone-Biloela (due to Liquefied Natural Gas development, agriculture and mining).

Table 53 provides a snapshot of Queensland's economic infrastructure across the four sectors of transport, water, energy and communications. The table notes the capacity of each subsector and its rate of utilisation in 2011, along with historical (2011) and projected (2031) DEC for each subsector.
