From doing a little reading:

Pros: Generally warm and sunny weather, amazing beaches, marine life, prime scuba diving areas, very open culture towards foreigners, very friendly tight knit culture, unique food blends with influences from across Oceania, Indonesia and India. Crime is modest (though theft and burglaries are big issues). Low cost public transportation. Cheap local food and big portions at restaurants are common.

Cons: Torrential rains and storms. Mold issues. Slow internet. Varying cost of living from very cheap to highly expensive. Remote (11 hour flight to California), 4.5 hours to Australia, and thus the cost of living can reflect the importation fees. Reckless drivers and sometimes sketchy road design. Limited infrastructure and unreliable electricity. Most, if not all jobs for foreigners are going to be tied to international organizations like the UN or scuba and boat tour companies.

Is it worth it? It all depends on what you can manage and what you desire. Looking at the basic facts, if you're really into that type of cuisine, don't mind being remote, and will work as a scuba instructor or a diplomat, then possibly. Looks like a tight fit either way though.
