Considering changing server, looking for more info

Hey guys. I've just resubbed after a long break and was looking at moving to a new server as Balmung didn't really have much of an Oceanic playerbase.
From what I hear Behemoth/Tonberry are the unofficial oceanic servers, but I was hoping to hear a few opinions from players here as to how many Aus/New Zealand players are around.

More specifically I'm looking to know how easy it is to get into a group for high end duties like coil etc. Only raiding during the day can be a bit annoying.
