The petroleum industry is broadly split into upstream and downstream petroleum sectors. The upstream sector refers to exploration and production of crude oil while downstream refers to refining of crude oil and the distribution and sale of petroleum products.
The Audit estimated total throughput at petroleum terminals in Tasmania of 1,042 ML in 2011.
The DEC of petroleum terminals was $14 million.
The Audit projects an increase in throughput of 0.9 per cent per year, equating to throughput of 1,255 ML per year by 2031 - a difference of 213 ML per year. This is projected to lead to a DEC of $17 million in 2031, an increase of $3 million.
