The Queensland Government has announced all foreign-flagged cruise ships will be banned from entering its waters by midnight.
The move follows a national order from the Australian Border Force, and comes as a a criminal investigation is underway into the Ruby Princess as the largest single source of Australian Covid-19 infections, accounting for around 10 per cent of the total.
The Premier says the remaining four ships are just refuelling and "they'll be on their way as well".
Around 119 of Queensland's 934 coronavirus cases can be traced to cruise ship passengers.
There are currently 5,895 cases of Covid-19 in Australia and 45 deaths.
Although the amount of daily new cases has been declining the authorities have reiterated that is no cause for complacency. And with some states and territories yet to announce their numbers, it is looking like the decline will be less pronounced today if at all.
