Sydney transit services are well equipped to get you anywhere you need to go in the city and beyond. There are five modes of public transport for you to choose from. Of course the ones you choose depend a lot on where and how far you are going. With the exception of the Metro Light Rail, Sydney transit services are coordinated by the Government of New South Wales. You can find detailed information and a trip planner for all of the services they coordinate at NSW Transport Info.
The key components of the Sydney transit system are the Transport Sydney Trains which operate from the outlying regions right into the centre of the city, Sydney Buses which offer extensive coverage both within the heart of the city and all of the outlying communities; and Sydney Ferries which take advantage of Sydney's extensive inland harbour.

The most convenient and least expensive option to pay for your fare is to purchase a reloadable OPAL card. It has a daily and weekly fare cap and offers a significant discount on single fares. See Sydney Transport Fares for the most economical options for getting around during your stay in Sydney.
Walking is a great (and of course free and healthy) option for exploring Sydney. About 80% of the attractions featured on this site are located inside an area that covers less than 5 square kilometers. With a little bit of planning you can easily walk from one attraction to another. To facilitate that we outline several different Walking Tours on our site.
