Flu in Australia: What You Need To Know
Influenza is a health issue in Australia as it affects all ages. However, complications can affect older people, young children, pregnant women, or those with health issues, including people over the age of 65. Bureau of Health Surveillance has reported that flu poses a burden on the health care system, particularly in winter. In 2025, influenza activity picked up in May, and from that point onwards there was an increase in hospital cases, and it continued to increase, especially with children under 5 and adults over 65.
National surveillance systems collect and record confirmed cases of influenza. Systems also measure trends in age, location, and timing. The Influenza Union suggests that flu, unlike the common cold, requires health prevention and early detection through an online GP consultation.
Understanding Influenza Symptoms and How to Identify Them
We examined the influenza surveillance systems to better understand the research, how influenza affects different categories of the population, and how influenza symptoms can be identified.
The common flu ...
... symptoms are similar to the common cold and can include:
fever
dry cough
blocked or runny nose
sore throat
fatigue
aches
a headache
Because of the similarity of influenza symptoms to cold and flu symptoms, it can make it difficult to identify influenza.
Key Findings from Influenza Surveillance and Prevention in Australia
Some things we found to be the most important were:
Symptoms of influenza can appear suddenly and cause severe fatigue and aches, which can mimic or be more than the discomfort felt by common colds.
Youth under 5 years old and adults over 65 years old are also at an increased risk of becoming seriously ill with influenza.
Surveillance of influenza is reliant on testing, meaning confirmed cases of influenza are not the only cases that exist.
Preventative measures such as vaccination are still the most effective ways to reduce influenza infection rates.
Influenza analysis and vaccine uptake are ongoing for the entirety of the flu season in Australia.
One of the strongest features of this analysis is that frequent data sources collected by various government agencies are analysed to inform Australia's understanding of seasonal flu.
There are deficits to this approach as well. The data presented can change as more reports are added, and laboratory-confirmed cases are a fraction of the burden that actually exists. Symptoms of the flu can be shared with other respiratory infections and therefore should not be used as an indicator of one infection. People who are unsure about their symptoms can consider discussing their concerns with a qualified healthcare professional for appropriate medical advice.
Raising Awareness About Influenza Risks and Vaccination
To continue elevating awareness for influenza in Australia, we need to stop viewing influenza as a normal seasonal discomfort. Instead, everyone needs to know the signs and prevention of influenza, as well as when they should seek medical help.
Vaccination information should be easily accessible to the public, and it should be known where vaccinations can be obtained. Influenza vaccinations are available through the Australian government for the public, private physician practices, as well as pharmacies.
Informed awareness of both the flu vaccine and flu shot should also exist during the flu season. Informed people should also know if they can obtain a free flu vaccine, as well as if they are vaccine eligible, and talk to a healthcare professional about their vaccine concerns.
An informed awareness of the flu also includes the importance of good public communication. This includes:
staying home when unwell
helping to reduce the flu risk to vulnerable people by limiting transmission
people contacting healthcare professionals for concerns of worsening and severe symptoms
Future research should also evaluate:
hospitalizations
deaths
vaccination coverage
the differences in vaccination coverage across different age groups
Current immunisation data in Australia are updated regularly, so health departments can continually conduct vaccination surveys.
Evidence suggests that to help reduce the impact of flu, the goal should also be about helping individuals understand their personal risk. This should also include encouraging evidence-based prevention strategies. This should also not be about trying to create panic, but about giving high-quality info.
