In addition to the previous $1 million announced on 1 January 2011, BHP Billiton is donating a further A$10 million to the Queensland Premier's Disaster Relief Appeal to assist with Queensland flood relief and recovery efforts.

"As a major employer in Queensland and given our large contribution to the Queensland economy, we want to play a leading role in the recovery efforts," said BHP Billiton chief executive Marius Kloppers.

We have increased our donation to demonstrate our support for the State in which so many of our people live and work, and hope that others will also be able to do so."

BHP Billiton metallurgical coal president Hubie van Dalsen also noted the role played by the company's workforce in recovery efforts.

"Our company and our workforce will continue their direct on the ground recovery work and rebuilding efforts in Central Queensland, especially in Emerald, in the months ahead," he said.

The resource giant also said it will match all employee donations made through the company's matched giving program.
