Safety Bay Road is an east-west metropolitan road located in the City of Rockingham, about 50 kilometres (31 mi) south of Perth, Western Australia. The road starts in Rockingham's coastal suburbs and heads south from Peron past Lake Richmond. The road then turns left at the coast with a roundabout with Arcadia Drive which is a coastal road in Shoalwater. Safety Bay Road takes a left turn and extends past Ennis Avenue and Warnbro railway station to the newer suburban estates at Baldivis, before ending just past the Kwinana Freeway. As such, it forms a key link between Rockingham, Perth and Mandurah. Until 2009, the end of the road marked the start of the Kwinana Freeway.
