Plug guide for Oceania

Oceania is dominated by the Australian/New Zealand Type I plug at 230–240 V, 50 Hz — Australia, New Zealand, Fiji, Papua New Guinea, the Solomons, Samoa, Vanuatu and Tonga all use it. The Pacific island states under US influence (Marshall Islands, Micronesia, Palau) instead use Type A and B at 120 V, 60 Hz. There's no in-between: pick your adapter once you know which side of the Pacific your destination falls on.
