Some doctors are blaming these numbers on this year's batch of the flu vaccination.
But, the government's chief medical officer, Professor Brendan Murphy, says any suggestion the vaccine chosen was based on cost, is false.
According to the Immunisation Coalition, there were nearly 91,000 (90,861) laboratory-confirmed notifications of influenza in Australia last year.
But so far this year, there have been nearly two-and-a-half times as many cases, with almost 220,000 (217,559) notifications.
New South Wales was the state hardest hit, followed by Queensland, Victoria, and South Australia.
Some GPs believe the quality of the vaccination isn't the reason for this year's dire numbers and the key is to get more people vaccinated.
