Transport Minister Gladys Berejiklian says there will be more than 1750 extra bus and ferry services a week when a new timetable begins next month, but some routes will be cut and two wharves will be closed.
The bulk of the new services will be buses in western Sydney, with another 1284 weekly services scheduled to start from October 20, according to the government's figures. There will be 429 extra weekly bus services from the inner west.
In addition, another six new bus routes will start with the new timetable.
But there will be only 55 extra ferry services a week, Ms Berejiklian announced at a press conference at Cabarita Wharf on Tuesday, despite billing the new timetable as the 'biggest change in a generation.'
Four of the six new bus routes are in western Sydney, one in the eastern suburbs and another in the inner west.
In the west the new routes are the T72, Blacktown to Quakers Hill via Sunnyholt Road; the 783 from Penrith to Jordan Springs; the 800 from Fairfield to Blacktown via Polding Street; and the 810X from North Pemulwuy to Parramatta.
In the eastern suburbs, the new route is a merger of two old routes. The 418 and 357 will be joined as a new Burwood to Bondi Junction 418, running via Marrickville and Mascot.
The new inner west 425 will run between Tempe, Marrickville and Dulwich Hill.
Also in the east, the 370 will operate on a summer timetable year round, meaning there will be more late night services to Coogee in the winter.
In the north shore and northern suburbs, three routes will have extra services at peak periods - the 265, 225 and 230.
In the west there will be increased frequencies on a number of routes to and from Blacktown.
Ms Berejiklian says this is the first occasion bus, train and ferry timetables have been written together.
But the timetable means the end for ferries at two wharves the government says are little-used: Bayview Park and Balmain West.
The release of the ferry and bus timetables follows the release of a new train timetable last week, which delivered a net increase in train services but changes to a number of train patterns that will inconvenience some commuters.
