This is the third outbreak of COVID-19 in a long term care facility, which house populations especially vulnerable to the disease.
Health Minister Kim Wilson in making the announcement late Saturday, said that to date, 28 people had recovered, eight were hospitalised and were still under public health monitoring, but did not need hospitalisation.
Officials with the Indiana State Department of Health say they have been working with the facility since their help was requested on March 26.
Some on board tested positive for the coronavirus.
A 74-year-old woman died in John Hunter Hospital and a 79-year-old man died in the Northern Beaches Hospital. There are also 20 cruise ships at port or anchorage in the US with known or potential COVID 19 cases among the crew members.
There are 2854 cases in NSW, with 141,777 people tested - the most in any state. More than 2600 people were tested in the past 24 hours.
"The fact we had nine new cases clearly indicates we are moving in the right direction, but we still have a lot more to do", Mr Hazzard said. "These cases just confirm what we have been learning: this virus easily spreads from person-to-person, and the actions taken to slow its pace will allow our healthcare workers to continue to providing care to trauma, significant chronic conditions, acute issues like heart attacks in addition to respiratory infections like flu and COVID-19".
Eleven sick crew members who have been evacuated from the ship remain in Sydney health facilities.
The number of confirmed cases of COVID-19 in Bermuda, has now risen to 50.
The deaths involve people who were residents at Bethany Pointe in Madison County.
Mr Hazzard said he was concerned about people's mental health and said people should try and bring back "that sense of community".
