I just got back from an Atlantis vacation. With over 600 guys there, I saw plenty of aussiebums.
I saw these there and really liked them. http://www.aussiebum.com/en/swimwear/842/blade/
Too bad they are $64
I would recommend avoiding the Wonderjock Classics. The material bunches up and it looks funny. The regular Classics are fine, as are the Wonderjock Loose (oddly enough).
I am a big fan of the Tuff-Az. I love the cut and the material. I find the a bit sexier than the Classic. I'm wearing them in a couple of my profile shots.http://www.aussiebum.com/en/swimwear/451/royalty/
Lots of guys were wearing the Precision squarecuts and they looked good. But as I mentioned, they were hardly unique.http://www.aussiebum.com/en/swimwear/1080/knife/
You only have one body shot, but judging from that I would think you would look good in any of the suits I and the previous poster mentioned.
