Two of the latest cases are a 4-year-old child and a 10-year-old child from the same family.
The Ruby Princess ship docked in Sydney on March 19, with the number of diagnosed passengers who were aboard climbing to 141.
More than 100 of those passengers have been diagnosed in New South Wales while 34 have been diagnosed interstate.
One of those passengers, a woman in her 70s, became the eighth person to die from the disease in Australia.
Meanwhile, the West Australian premier Mark McGowan said tourists will not be allowed into the state after its borders had closed.
"If you are a tourist wanting to come to WA, it's too late, please don't come," he told reporters on Tuesday.
Exemptions to the 14-day isolation rule will only be made on compassionate grounds and for essential workers.
Mr McGowan said interstate travel must be avoided, adding restrictions on travelling between WA's nine regions would be announced soon.
He also warned beaches would be closed if people did not practice social distancing.
"I don't want to be doing this, but if we have to protect people from themselves on our beaches, then we will."
Mr McGowan said the priority was protecting the elderly and indigenous communities.
"This is pretty extreme but this is the process we are now going through," he said.
"Stop your holidays, stay home, just do your essential stuff."
