A bulk carrier ship currently sitting off the Kwinana Bulk Terminal is in lockdown after a crew member developed flu-like symptoms last night.
The crew member is isolating on board the ship and the rest of the crew are not allowed to disembark.
The BW Matsuyama, from Singapore, is due to leave tomorrow night.
The crew member will be transported to Fiona Stanley Hospital later tonight or tomorrow to be assessed under COVID-19 precautions.
