Transport for NSW has confirmed that there will be a reduction in services as Sydney reaches record COVID-19 case numbers. These disruptions will affect both train and bus services.

From now until further notice, bus services operated by State Transit in the Eastern and Northern Suburbs and bus services operated by Busways in the North West and Western Suburbs will be operating to a reduced timetable. Services may be cancelled at short notice, but efforts will be made to at least operate to a Sunday base frequency across the network.
Sydney Trains, NSW TrainLink Intercity and Regional train timetables across the State will be adjusted from Monday 10 January, with services adjusted to an enhanced weekend timetable. This will be similar to the dynamic timetable operated during August, with addition peak services to aid with social distancing.
