EAST TIMOR: Relies heavily on oil and gas for its economy, but had been running out of resources. New deal means East Timor will receive 70-80 percent of Greater Sunrise field – depending on whether resources are processed in East Timor or Australia – compared with 50 percent under 2006 agreement with Australia

AUSTRALIA: Had previously argued that border should be closer to East Timor, following edge of continental shelf. New agreement could lead to renegotiation of maritime border with Indonesia, whose economic zone – set out in 1997 Perth Treaty – extends much further south than its seabed (oil and gas) rights
