The public is being asked to keep an eye out for distressed marine wildlife during the annual winter migration.
Winter fronts bring migratory animals such as turtles, sea snakes, penguins and seabirds to the State and they can become stranded or sick, according to DEC wildlife officer Karen Smith.
"Now that winter is in full swing, the presence of these animals on WA beaches may become more prevalent," she said.
"Storm-blown seabirds may also be seen across the State and wildlife rehabilitators have already attended to several of these incidents.
"This included a lost and tired southern fulmar, a large seabird related to mutton birds, that was found more than 6km from the coast in the Perth suburb of Stirling.
"Further south in Rosa Brook near Margaret River, a yellow-nosed albatross was found 18km from the beach in a farmer's paddock.
Other marine creatures such as turtles and sea snakes are carried by the Leeuwin current and wash up on the coast during rough weather, she said.
People should refrain from handling the animals themselves and are urged to instead contact the DEC Wildcare Helpline on 94749055 if they discover marine creatures in distress.
