I may be more qualified to comment on Pacific affairs than many of the other commentards here, as I am a Pacific Islander.
The particular Pacific Island I live on has closer ties to Tonga, Samoa, the Cook Islands and Fiji than Nauru, but those places have many of the same problems.
Pacific Islanders tend to be friendly, laid back people with a live and let live sort of take on life. The ones I deal with in my day to day life are generally a pleasure to deal with. Of course there are exceptions, but that's true of any group.
The problems the Pacific nations have tend to stem from their leaders. A quick look at the recent history of Fiji ought to make that clear. The average indigenous Fijian has no animosity towards Indo-Fijians at all, but various military hard man have made good careers out of trying to create inter ethnic strife.
Tonga is another example where a weird sort of faux-western "Royalty" owns almost all of the economic assets and a "Nobility" help keep the commoners in check.

We're happy to have them come to live here, as it fills our rugby teams up with genial giants with great balls skills.
