Queenstown New zealand Highlight
...Italy is an amazing experience... and not comparable to anything else!
For a great view of the city (especially at night) go to the top of the Eiffel Tower at Paris. It also offers a great vantage point for viewing the water show at the Bellagio.
I'm a Bondi local...it is always packed with people...if you're looking for a more chilled beach hang out, check out Tamarama, Coogee or Bronte beach, all 5-10mins from Bondi.
