Influenza vaccination has been on the decline since 2023, especially in many priority risk groups. Healthcare professional recommendation is the strongest predictor of a person’s decision to vaccinate. See the following resources to equip you and your team with all the information and resources necessary to prepare for 2025 influenza vaccination season.
Annual influenza vaccine can be given anytime from April onwards to provide protection for the peak flu season (June to September). The highest level of protection happens in the first 3 to 4 months after vaccination.
Official advice on influenza vaccination 2025, including on which flu vaccines are registered and available for use in Australia in 2025, is contained in the following documents:
The National Immunisation Program (NIP) has experienced a short delay in the supply of Vaxigrip® Tetra until early April.
FluQuadri® vaccine will be supplied as an alternative for children 6 months to under 5 years until the supply of Vaxigrip® Tetra becomes available.
Due to the late addition of FluQuadri® to the NIP, vaccine packaging will not be labelled with “Government Funded Program – 2025” like other NIP flu vaccines. Immunisation providers must ensure this vaccine is clearly labelled as NIP-funded and only used for children aged 6 months to less than 5 years.
2025 NIP influenza program resources have been updated to include this change, including ATAGI statement, NIP program advice, NSW Health website, and the Department website.
For clinical advice, refer to the Australian Immunisation Handbook Influenza (flu) chapter.
The NSW Health 2025 Influenza Vaccination Provider Toolkit has been developed to assist providers with managing roll-out and implementation of their influenza vaccination program in 2025.
The 2025 influenza vaccine presentation and free vaccine eligibility poster (Appendix 2) is included in this resource pack, which contains 2025 funded vaccines brands and suitability by age groups.
See NSW Health 2025 Influenza program website for further information and resources for the upcoming influenza season.
The National Vaccination Insights project have conducted a major national survey to understand what motivates adults in Australia to receive the influenza (flu) vaccine. The findings from this study offer important insights that may help inform strategies to reverse declining flu vaccination rates in Australia.
Under the Australian Immunisation Register Act 2015 it is mandatory for vaccination providers to report all influenza vaccines to the Australian Immunisation Register (AIR). Influenza vaccines administered overseas by a recognised vaccination provider can also be reported to AIR.
Recording the correct “Vaccine type” for flu vaccines:
Overseas flu vaccines
If a flu vaccine was administered overseas and the batch number is not available, enter ‘notrecorded’ (one word, no spaces) into AIR.
For more information, see Submitting information using the AIR site.
Free seasonal influenza vaccine is funded under the National Immunisation Program (NIP) for the following groups at higher risk of complications from influenza:
Flu vaccinations help keep children safe and are free for children 6 months to under 5 years. A reminder to immunisation providers that it is never too late to get an influenza vaccination, since influenza can circulate in the community all year round. Influenza vaccination should be recommended for everyone 6 months and older. Children under nine years getting their influenza vaccination for the first time need two doses of vaccine, given one month apart. Influenza vaccination is recommended for pregnant women at any stage during pregnancy.
Children can become seriously ill from influenza and in some cases it can be fatal. This was the case for 2-year-old Lucy who developed serious complications from influenza. The Department of Health and Aged Care has a video about Lucy’s story you can play in your health setting to remind guardians of the dangers of influenza in young children.
With this year’s flu season underway and flu vaccines now available, AusVaxSafety has commenced its routine surveillance of influenza (flu) vaccines in use in Australia in 2025.
Flu vaccine safety data will be made available on the AusVaxSafety website from the week starting 14 April and will be updated weekly throughout the duration of the 2025 season.
AusVaxSafety has monitored the safety of flu vaccines administered to Australians of all ages since 2017, gathering details about any side effects experienced in the days after flu vaccination from more than 1 million people (or their parents/carers) over that period – including over 200,000 surveys completed in 2024.

NSW Health has launched their 2025 Respiratory Campaign Toolkit for influenza (flu), COVID-19 and RSV.
Immunisation providers can place an online order using this link for materials and resources from the NSW Health Respiratory Illness campaign to be delivered to their clinic. The aim of this campaign is to promote flu vaccination, emphasise the benefits and ease of getting vaccinated, while also raising awareness of other respiratory illnesses.
