Keolis began operating a network of over 400 buses in Greater Sydney, with plans to convert 125 vehicles to electric

The eight-year contract, worth 580 million euros, was awarded on 28 May 2021 by Transport for New South Wales, the public transport authority for the state of New South Wales. It is the first time the network is being run by a private operator.

This contract, which is the largest involving the introduction of alternative-energy buses in Australia, is part of the government's move to convert the region's entire bus fleet to electric power by 2030.

To enhance the passenger experience and boost network use, Keolis Downer has pledged to increase efficiency and reliability of the services and contribute to the network's energy transition.
