There are many public transport options in Sydney. These include bus, train, taxi, light rail, monorail and ferry. Fares are inexpensive. You can buy a ticket when you board or buy a prepaid pass. Prepaid passes can either be for a period, like a week, or for 10 rides. Prepaid passes can be bought from Bus, Ferry and Rail counters or from news agencies.
In April 2010, Sydney launched a new transport ticketing system called MY ZONE which is a consolidated ticketing system for all buses, trains and ferries on both private and public services. This means that Sydney-siders can buy one pass and be able to travel on buses, trains and ferries. Alongside the intergrated ticketing is a joint trip planning and information site for all modes of public transport. http://www.131500.com.au
Sydney public transport is safe. All trains have security cameras installed and are attended by transport guards. Accidents are extremely unusual. Taxis are monitored and identification of all drivers is required.
Sydney public transport is mostly environmentally friendly. Buses run on CNG (Compressed Natural Gas) or diesel and have particle filters which reduce their particle emissions by 90%. Trains, light rail and the monorail run on electricity. Currently most of Sydney’s electricity is generated from coal power but is slowly changing to wind and other sustainable means.
