Ruby Princess?

One of the cruise liners circling on the horizon.
5 liners left Sydney yesterday under instructions from the government. I am unsure how many remain ...all have crew only and are reluctant to leave Australian waters as they will be out of reach for emergency health care.
It has been quite eerie watching these ships circle and wait. It certainly is a very difficult decision for the government. 
I not sure how many of us will be embarking on a cruise in the future.
