Health Minister Greg Hunt convened a meeting of state and territory health ministers to discuss the situation on Saturday.
“Australia has processes in place to identify and treat cases such as the novel coronavirus, including isolation facilities in each state and territory,” Mr Hunt said.
Australian Chief Medical Officer Professor Brendan Murphy said it was possible other cases would be confirmed in the coming days or weeks.
“Symptoms include fever, coughing, sore throat, vomiting and difficulty breathing,” Professor Murphy said.
“Difficulty breathing is a sign of possible pneumonia and requires immediate medical attention.”
Queensland Health has urged anyone who has developed a fever or respiratory symptoms within 14 days of travel to China – in particular Wuhan, where the virus first emerged – to see their GP immediately.
People are asked to call ahead and advise the clinic of their symptoms so precautions can be taken.
