I'm late to the post, but I notice the most recent response is 12 March 2012 so I'll jump in. I live in Brisbane and my area of interest is bird photography. I used to be a regular reader and contributor of posts, but over the past 12 months I've been on a national committee helping to merge PhotoBOCA and Birds Australia into a national bird photography group called BirdLife Australia Photography.
I'm also the Moderator for BirdLife Southern Queensland Photography, which will be a "stand alone" branch within the branch network. As you see my time has been taken up considerably by other duties.
I will be travelling down to Gluepot Reserve, which is near Renmark SA, next month and expect to be on the road for about 3-4 weeks. If anyone is interested in catching up for some bird photography on the way, let me know.
But back to the main point. This topic has bounced around for a long time and, until someone puts their hand up to own the issue, it will keep on bouncing around. Surely Nikonians in their respective towns/cities can get together? It does not have to be a national group to start with.
If the enthusiasm is there, the group will grow. You could start with a Skype hook-up or short newsletter to "test the water". Don't die wondering!
I've just renewed my Nikonians membership for another 2 years, well worth the money and I just couldn't help having a bit of a rant. My apologies.
