All ferries to and from Rottnest Island have been cancelled today due to the rough weather conditions.
A Rottnest Island Authority spokesperson said pending weather conditions this afternoon, one ferry may be able to return from the island about 4.30pm today.
But the single ferry, currently berthed at Rottnest Island, will not have the capacity to bring all visitors back to Perth.
Some visitors will need to spend the night on the island.
The spokesperson said if weather conditions improved before 4.30pm a second ferry would be send to collect the remaining visitors. She said the authority was awaiting further advice from the State Emergency Services.
Earlier this morning a ferry was set off for Rottnest Island but was turned back after it could not berth due to the high swell.
All visitors remaining on the island tonight will be provided with free accommodation.
