G'Day again Squip,
I've dived under the wharf at Green Island, and there's a lot of fish there. Obviously you're not going to get the same depths in close as out close, but if you're after a cheap day trip, it'll give you something to do. Generally, the outer reef is much better quality (ie bluer water, more vivid coral, etc) than the inner. The Quicksilver is about $200 australia per head (maybe as much as $150US?) for a day trip.
What times will you be up there? If you're going to be around later in Dec and are looking for someone else to dive I'll come say hi
Brad
