Hey, I've done it! I'm a certified diver now and this certificate is valid for the lifetime!
Today we had our last open water lesson in the morning and in the afternoon we had a chance for an extra "fun dive", which everybody decided to do as well. First I thought to skip it, because I was tired after the first dive, but then I had some lunch, took a short break and felt much better so that I also went for another dive. Because we did 2 dives with a short break on the surface each time (yesterday and today), we've got 6 open water dives now in our dive log. This is amaizing, even though that we were not so lucky with the visibility.
I hope I can see more of the Great Barrier Reef when I get to Cairns...
