If you want a snapshot of Australia's appeal, look no further than Sydney: The idyllic lifestyle, friendly locals and drop-dead natural beauty of this approachable metropolis and its attractions explain why the country tops so many travelers' wish lists. But Sydney is more than just the embodiment of classic antipodean cool—the city is in a constant state of evolution. A list of what to do in Sydney might start with the white-hot nightlife, with its new cocktail bars and idiosyncratic mixology dens. Inventive restaurants helmed by high-caliber chefs are dishing up everything from posh pan-Asian to Argentine street food, while the famous dining temples that put Sydney on the gastronomic map are still going strong too.

The famed harbor is among the top sights—home to twin icons the Sydney Opera House and the Sydney Harbour Bridge, it is the stepping-off point for some of the city's best cultural attractions and sightseeing. In one day you can sail around the harbor, get a behind-the-scenes tour of the opera house and climb the bridge, with time to spare for people-watching over a flat white at a waterfront café.

Speaking of water, when you plan what to do in Sydney, you will want to include the iconic beaches, where surfers, office workers and tourists alike converge on some of the most gorgeous shoreline scenery anywhere. Bondi, Bronte and Clovelly are all within easy reach of the Central Business District, as is Manly, a charming seaside town located a short ferry ride from Circular Quay. Beyond the city you'll discover UNESCO World Heritage Sites and the chance to encounter Australia's cuddliest wildlife—a perfect way to round out your envy-inducing Sydney photo collection.
