Record Flu Surge Alarms GPs as Vaccination Rates Stall in Australia

Published in News on February 01, 2026

General practitioners (GPs) across Australia are expressing serious concern over a record-breaking influenza season in 2025, as flu case numbers exceed previous highs while vaccination rates stagnate and even decline. With more than 410,000 laboratory-confirmed influenza cases recorded so far this year, the scale of the outbreak is prompting calls for stronger vaccination efforts, public awareness campaigns, and improved access to immunisation for at-risk groups.

This year’s figures have already surpassed the previous all-time high of 365,000 cases recorded in 2024, according to the Royal Australian College of General Practitioners (RACGP). RACGP President Dr Michael Wright described the situation as a “wake-up call,” emphasising that rising cases combined with stalled vaccine uptake are a dangerous mix.

Vaccination Rates Falling Behind

While influenza infections are climbing, Australia’s flu vaccination coverage has not kept pace. Only around 25.7 per cent of children aged six months to five years have been vaccinated in 2025—the lowest rate since 2021—while uptake among adults over 65 has also slipped, with about 60.5 per cent vaccinated, marking the lowest rate in years. These figures are well below the levels needed to protect the most vulnerable populations.

This downward trend worries health experts because vaccination remains the most effective way to prevent severe flu illness, hospitalisation, and death. Low immunisation rates also increase the risk of outbreaks in settings such as schools, aged care facilities, and hospitals.

To address this, several states—including Queensland, New South Wales, South Australia, and Western Australia—have committed to introducing free childhood intranasal (needle-free) flu vaccines ahead of the 2026 season, a move that could remove barriers to uptake for young children. GPs hope that the broader rollout of such programs will support improved vaccination rates next year.

Why the Concern Matters

Why are health professionals so worried? For older Australians and young children in particular, influenza can lead to serious complications, including pneumonia, dehydration, and in some cases death. Annual flu vaccination significantly reduces these risks, yet complacency about influenza remains widespread, with many people wrongly assuming it is a mild illness rather than a contagious respiratory infection that can be severe or life-threatening.

The consequences of low vaccination rates are not theoretical. Hospital admissions related to influenza have already increased in recent years as flu activity rebounds in the post-pandemic era, with some health services reporting more admissions for respiratory illnesses than seen before COVID-19. These pressures compound the usual seasonal demand for emergency care and require careful planning to ensure hospital capacity can cope.

Impact on Hospitals and Healthcare Resources

A surge in flu cases inevitably places added strain on hospitals. As more people experience severe symptoms or complications, emergency departments and wards can become busier, which increases waiting times and extends hospital stays for those with serious illnesses. Strong vaccination coverage protects not only individual health but also helps prevent overwhelming healthcare services.

Globally and in Australia, seasonal influenza has been a major cause of hospitalisation among older adults, with thousands admitted each year prior to the COVID-19 pandemic. Effective vaccination not only reduces influenza cases but can also lower the incidence of related complications such as bacterial pneumonia or exacerbation of chronic conditions, which are common reasons for extended hospital stays.

Breaking Down Barriers to Immunisation

Experts emphasise that improving flu vaccination rates requires reducing barriers and increasing public understanding. Needle-free vaccines for children are one example of how flexibility in delivery can improve uptake. Other strategies include strengthening outreach through general practices, pharmacies, community clinics, and targeted messaging for older adults.

Public health bodies also encourage early vaccination to maximise protection before flu season peaks. Because immunity takes around two weeks to develop after vaccination, getting a flu shot early can reduce the risk of infection during the height of seasonal spread.

A Call to Action

In the view of Dr Wright and many other health professionals, reversing the trend of stalled vaccination rates must be a priority. As Australia heads into future flu seasons, targeted efforts to increase immunisation uptake—particularly among young children and older adults—will be essential to reduce the burden of disease and protect the health of communities nationwide.
