The company posted a profit of US$679 million for the first six months of the year, down 39% on the US$1.1 billion profit booked in the first six months of 2014.

This came as first half operating revenue slid 28% year-on-year, from nearly US$3.6 billion to less than US$2.6 billion.

Woodside attributed the fall in profits to lower commodity prices following the steep decline in oil prices since the second half of 2014 and, to a lesser extent, lower sales volumes which dropped 2.7%
