Sydney is a multicultural city with food choices for every taste. Most popular theme seems to be water, everything from Sydney Harbour to the many beaches (Bondi the most popular) attracts visitors. There are a good verity of markets in most parts of the city and lots of fashion shopping. Interesting architecture new and old, including convict. Some old buildings have a uniquely Australian history and a slow walk around the city interspaced with coffee and snaks is rewarding. If golf is you, no worries. Art, Music, Museums all easy to find and a few drinks and some fun when the sun goes down? again, no worries.
Sydney is the prettiest city in Australia. The bridge climb is the best thing to do and the Reptile Park near Gosford is a must see best animal park i have seen. The beaches on the south coast of Sydney are beautiful especially hyams beach south of Woolongong which has the whitest sand in the world.
