If you head to Los Negros Island, east of Lorengau, check out the remains of the US airbase at Lombrum. There's a fine anti-aircraft gun as you enter, and rows of old hangers. General MacArthur's HQ is still in use by the PNG Navy. The former Australian refugee detention centre, where asylum seekers who were arriving in Australia were processed during Australia's 'Pacific Solution' days, is located here too.
