G'day from Australia
I read with interest the threads about Bougainville and the Solomons. Bougainville, the Northernmost island of the Solomon group is three hours by prop-jet from Port Moresby; less these days by Fokker F28 jet. I'd say about 1-1/2 hours. Port Moresby is, in turn, five hours by jet from Sydney.
I lived on Bougainville for some years in the 1970's. Its capital (or the biggest town) was/is Arawa, next is Kieta. Bougainville sits about 6 degrees off the equator.
I see some discussion about Buna: Buna isn't on Bougainville, it's on 'mainland' New Guinea. Buna and Gona were the scenes of some of the most bitter fighting of World War 2 and were also the scene(s) of some of the first defeats of the Japanese, after they were driven from Papua across the Kokoda track.
Iron Bottom Sound is mentioned: it's the 'harbour' - or part of the 'harbour' - which serves Honiara. Honiara is the capital of Guadalcanal, the Southernmost island if the Solomon group. Apparently, during the war, the Japanese regularly ran what became known as the 'Tokyo Express', an escorted supply convoy, down 'The Slot', causing untold grief for the Allies, with consistent loss of shipping. Iron Bottom Sound gets its name from all the hardware on the sea floor. It's a marine park, these days, as all the wrecks provide hangouts for marine life.
Somebody else has suggested that Bougainville is hot and he's right. Six degrees off the Equator IS hot! Bougainville has also been the scene of a bitter secessionist civil war, pretty much since the large copper mine closed there around 1990. The differences have quietened down, now, but the move for Bougainville to secede from Papua-New Guinea is still active.
Hope this all doesn't sound too 'schoolmasterish'!!! It's well-intended...
