A 30-kilogram seal has made its way back into the water after fears it had suffered a shark bite led to the closure of Mullaloo Beach.
Officers from the Department of Parks and Wildlife monitored the injured bull seal throughout Sunday until the animal returned to the ocean, a spokesperson said on Monday.
Rangers sectioned off an area around the seal and waited with it until the late afternoon, when it returned to the ocean.
Surf Life Saving WA reported the adult male seal may have been bitten by a shark, and a helicopter patrol was carried out but no sightings were made.
Shark warning in Scarborough
Further south, Scarborough beachgoers have been warned to look out for sharks, after monitoring equipment washed ashore on Saturday.
Tagged sharks in the area will not be identified by the monitoring network until it is fixed.
A buoy receiver used to alert authorities of nearby tagged sharks, broke free of its station off Scarborough Beach and was found on Peasholm Dog Beach.
The Department of Fisheries said staff members had begun plans to re-install the monitor in its normal location.
The tagged shark monitors are part of a range of shark hazard mitigation strategies in place.
Members of the public should report shark sightings to water police on 9442 8600.
