ATM machines near cruise terminal in Noumea?

Hi all!

I'm taking a cruise to Noumea and Vanuatu next month, and don't plan to get any local cash until I get there on the assumptions that

a) I can easily find an ATM during our half-day stops in Noumea and Vila, and
b) I can get some local currency out using my Commonwealth Bank keycard!

Are these assumptions correct?

thanks
