There are a few members here that are based there or travel frequently so hopefully they'll see your thread. Until then, here's my recollections from a work trip there 18 months ago:
POM was dangerous then, apparently. So much so, I was not allowed out of the hotel grounds (Holiday Inn) without a driver. Although that may just have been the over-zealous OH&S policy of the oil company, I didn't see any whiteys walking around. Other than the fabulous Parliament House, there's not a lot to see but a drive around was interesting. There's a yacht club, golf club, and my driver took me to a few art/craft-type markets.
I used kina to pay for my business visa on arrival (as directed by my employer) and I don't recall seeing an ATM in arrivals. I flew direct from BNE, but via CNS on return, using the domestic QP there after clearing C&I.
