We did the inaugural Hawaii to Sydney cruise back in 23 and Noumea was our least favorite port. There's some neat WWII history there if you're in to that (I am), but there's not a huge variety of excursions and the port is secured, so you can't just get off the boat and wander, you have to take a shuttle to "town," which consists of a couple of blocks worth of tourist traps and a "craft market" where all of the stall sell much the same thing.
