Wondabyne railway station is located on the Main Northern line in New South Wales, Australia. It serves the southern Central Coast area known as Wondabyne and opened on 1 May 1889. It is the only station in Australia that does not have road access.
Wondabyne has a quarry that is used intermittently and several houses which can only be accessed by boat from a jetty next to the station. As Wondabyne is a request stop, not all trains stop there.
Wondabyne Station is mainly used by bushwalkers on the Great North Walk and the homeowners who live on the other side of Mullet Creek which is a tributary of the Hawkesbury River.
