A liquefied natural gas (LNG) tanker operated by Energy Advance Co., a unit of Tokyo Gas Co., is moored at ConocoPhillips' LNG facilities in Darwin, Australia, on Wednesday, April 11, 2012. Darwin is in the express lane of Australia's two-speed economy -- a division the Reserve Bank of Australia used to separate resource-rich regions in the north that are powering growth and sucking in workers, from the tourism, manufacturing and retailer industries of the southeast that are teetering under a currency that has risen 65 percent in 3 1/2 years.
