So far this winter there has been a record number of people being admitted to hospital with flu-related illnesses, an expert has warned.
Demonstrating the advantages of private health insurance, Robert Booy from the National Centre for Immunisation Research and Surveillance at Sydney Medical School explained how health facilities have been under increased strain.
He noted that people have also been admitted to intensive care for complications arising from flu infections over the past three years.
Professor Booy continued: "It is difficult to know exactly why it is worse this year.
"Every year we chase the virus as it continues to mutate and we try to adapt, reviewing what is in the flu vaccine each year in order to keep up with changes in the virus."
The National Prescribing Service recently urged families to make sure they receive flu vaccinations ahead of the winter season.
Its clinical advisor Philippa Binna stressed that thousands of people a year are hospitalised due to flu and the complications that can arise from it.
Vaccinations not only help protect the individual, but also any at-risk people such as the elderly and pregnant they may come into contact with.
