Don’t let flu catch you in 2023: What you need to know about the upcoming flu season

With the 2023 flu season almost upon us, read on to learn what to expect, how best to protect yourself and why it’s especially important to get an influenza vaccine if you’re an older Australian.

Expect the unexpected

Flu is unpredictable. The circulating virus changes every year and protection from influenza vaccines wanes, so it’s best to be protected and get an updated vaccine each year before peak flu season (typically between June and September), as advised by the Australian Department of Health. The recent northern hemisphere winter saw multiple viruses circulating, not only was there flu, but there was also COVID-19 and respiratory syncytial virus (RSV).

2023 could see a resurgence in flu, so it’s important to take steps to protect yourself with influenza vaccination and good hygiene practices. See our 5 tips on how to protect you and your loved ones from the flu at the end of the article.


"Annual vaccination remains our best protection against contracting influenza, spreading influenza, preventing disease related complications, including hospitalisation and death."  -Dr Sarah Chu, General Practitioner, Turbot St Medical Centre Brisbane


Flu can disrupt your life

From ruining a holiday or missing days of work to developing a complication and ending up in hospital, there are many ways flu can disrupt your life. It’s important to remember that influenza is not just a respiratory infection, it can affect your whole body and various organs.

Why vaccination matters if you’re 60+ years old

Everyone aged 6 months and older is recommended to receive an annual influenza vaccine by the Australian Department of Health. But it’s especially important that older Australians protect themselves from flu, due to their greater risk of catching the flu and experiencing serious complications such as pneumonia, heart attack and stroke:

  • The risk of heart attack and stroke is increased in the days after flu infection
  • Recent flu infection can cause an increase in the risk of pneumonia
  • Catching the flu may also increase the risk of hospitalisation in people with chronic
  • conditions such as diabetes and asthma
