One of the coolest things in Australia are the pools/lagoons they build right next to the ocean. Sydney’s are the most amazing, with many of them built right in to the rocky coast and filled with the ocean water via pumps and waves crashing over the sides. Here’s the Bondi Icebergs Winter Swimming Club at Bondi Beach. If you look closely, you can see all the newbie surfer tourists drowning in the waves in the background.
