Australian liquefied-natural gas projects planned by companies from Royal Dutch Shell Plc to Woodside Petroleum Ltd. and valued at about $100 billion are at risk from rising costs and cheaper U.S. exports.
Natural gas trading at a 10-year low in the U.S. and discoveries in Africa also threaten to slow the development of Australian LNG ventures following the approval of eight projects to meet surging demand from China, Japan and South Korea.
