Good that you added both Manly and Dee Why. Minds may well differ, but we prefer Manly over Bondi as a surfing beach. Added plus for tourists you have the ferry ride. Dee Why has its own little point of interest - a line carried due east from Dee Why Point will see you at the top of the northern-most point of New Zealand. Strictly speaking, waters to the south of that line form the Tasman Sea, while those to the north are part of the Pacific Ocean.. So, if you want to be pedantically correct, neither Manly or Bondi beaches are on the Pacific.
Thanks for your expert opinion. I personally loved Manly and Dee Why as it felt relaxed and the waves were fantastic. But Bondi has its own vibe which is great too love the whole atmosphere there ❤️
