Well, I'm back @ work today, so I spent a bit of time in shell transferring the full photo collection from our QLD trip into a gallery.

The girl is Zen, my girlfriend... The guy with the long hair is an ex of Zen's that turned out to be a top bloke.
Word of advice (on that topic) to other (jealous) boyfriends - if your partner wants to hook up with an ex, and they approach you to ask if both you & her can meet up with them, it would be unwise to say no -
at least by going along, you get to suss things out properly and understand the connection they have - in this case, it turned out the guy is awesome & they have no dodgy affair-type connection.
*amendment by Zen* Zen explains that although there was a rebound fling between her & Matt, the dominant theme in their relations has been friendship.
Enjoy!
