For two weekends, I didn't see much when I snorkeled at Cottesloe. The water conditions were simply no good. That's why you haven't seen much 'action' in this blog lately.
Maybe I should go to the Marmion Marine Park next week. With some luck, I may be able to see some reef animals, e.g. sea stars.
This morning I had a good swim at Cottesloe anyway. Just me and my swimming goggles - no snorkeling mask, no fins. I haven't done that for a really long time!
