Southern Ports Chief Executive Officer Steve Lewis said Southern Ports has implemented a range of strict protocols and procedures to ensure the safety of their workforce and communities.
"Since the outbreak of COVID-10 we have operated under the advice of the Australian Border Force and both the State and Federal Departments of Health," Mr Lewis said.
New measures include anyone arriving in Australia from overseas being forced to self-isolate for 14 days, and International cruise ships being banned from docking in Australia for at least 30 days.
Mr Lewis said many International cruise lines had already commenced self-imposed freezes on their operations.
"All cruise ship visits scheduled for Albany, Bunbury and Esperance for the rest of March have cancelled.
"All cargo ship crew arriving in Albany, Bunbury or Esperance are required to adhere to a 14 day on board isolation period from the day they leave their International departure port."
