My husband and I had to cancel a trip to Philadelphia over Thanksgiving and decided to change our tickets to Sydney when we found a really great deal. We only went for a week, but we did so much, and it was so wonderful! I really recommend taking a day tour to Jervis bay. It has some of the whitest sand beaches in the world, dolphins, bizarre Port Jackson shark eggs washed up on the beaches—plus other stops on the tour were kangaroo valley, where we had kangaroo and parrot sightings, and a wildlife park where we got to pet and hold a baby koala. Also, make sure to try the Cadbury Cherry Ripe bars; it’s a shame we don’t have them in the US!
