Here is National Geographics Top Ten Beach Cities.
1. Barcelona, Spain
2. Cape Town, South Africa
3. Honolulu, Hawaii <<< Waikiki you must be kidding. I like the out of town Hanauma Bay Beach even with the $10 admission price. The admission was introduced a dozen years ago to reduce the damage to the reef. I can see the fish with the longest name humuhumunukunukuapua'a.
4. Nice, France
5. Miami Beach, Florida
6. Rio de Janeiro, Brazil
7. Santa Monica, California
8. Sydney, Australia <<< How come the women have their top on on Bondi beach in the National Geographic picture? It is a top optional beach

This is Sydney, not Melbourne.
9. Tel Aviv, Israel
10. Vancouver <<< Yeah we made it to the number 10.
