Nauru is an island state in the South Pacific Ocean. The dwarf state has a total area of only 21 km² (8 mi²) and a total coastline of 30 km (18.6 mi). This makes Nauru the second smallest country in Oceania after Tokelau and the seventh smallest worldwide. With 596 inhabitants per km², it is also the most densely populated country in Oceania. Nauru has no direct neighbours. Economic and fiscal sustainability remain key concerns for the government.

According to the United Nations Economic and Social Commission for Asia and the Pacific, Nauru relies on a C-band satellite used by Bendigo Bank and an O3b satellite used by Digicel. Digicel is the primary Internet service provider and mobile operator. A second Internet service provider, CENPAC, leases Internet bandwidth from Digicel and distributes it to government and state-owned enterprises. Internet connectivity on the island is very limited and unstable due to the vulnerability of the network infrastructure to bad weather and limited network coverage, with several blind spots.

The ETC is focused on preparedness activities in Pacific Island countries under its Pacific Emergency Preparedness and Response (EPR) project, led by WFP.
