The most scenic way to travel to downtown Sydney is by ferry. There are regular Manly - Sydney commuter services as well as services to other areas around Sydney Harbour. There is an extensive urban bus system and an urban train system. Once in downtown Sydney, travelling on foot is preferred for the Opera House, the Domain, Sydney Harbour Bridge and the Rocks Area and the major shopping areas. China town and Darling Harbour are not far away on foot or by monorail.
Full details are available at the tourist information booth.
Car hire Travelling around Sydney by car is feasible and not too difficult. But parking in downtown Sydney and in Manly can be a problem. Driving is on the left side of the road. Car hire is most economically arranged with your travel agent prior to leaving for Australia. You may need an international driving permit.
