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.
A great way to spend the afternoon in Paris? Grab some cheese, a baguette and some wine from the shops on the Champs Elysees and head down for a picnic in front of the Eiffel Tower!
I've found from experience the best and most reliable brand of adaptors for Australian travellers is Korjo. Check out www.korjo.com
