Douglas Wood has quite a large business over there. He'd be raking it in which hasn't really been reported by media.
From a UK article prior to kidnapping.
Australian Douglas Wood Barry, 56, an engineer by training, spent 25 years working for Bechtel, the US construction giant, before starting his own small joint venture construction firm. Since coming to Iraq two months ago, it has won two contracts, the renovation of a building inside the Green Zone, and a military camp in Falluja. He has 200 employees working at the two sites.
