So I think I have found them all! I used Google Earth, very good tool for this. As there are a couple of distinct geographical markers I have divided the total number into three sections.
Cronulla to Bondi, Manly to Palm Beach, Sydney Harbour inside the Heads. South Head and North Head split the ocean side and I have basically zoomed around from inside the harbour from North Head to South Head.
There are different kinds of ‘pools’ which have made the list, rock pools, netted tidal baths, and baths enclosed in boardwalks.
I have counted 49 in total. Stay tuned for the location list.
Cheers.
