In 2014, Beach Energy was the largest onshore oil producer in Australia. In March 2015, it was announced that incoming Beach Energy managing director Rob Cole will assume leadership of the company three months earlier than expected after freeing himself of commitments at his previous firm, Woodside Petroleum.
