A concerning trend is emerging: Australia's once-stellar child vaccination rates are plummeting, leaving vulnerable youngsters at risk! For years, Australia proudly stood as a global leader in childhood immunisation, consistently achieving the national benchmark of 95% of one-year-olds fully vaccinated before the COVID-19 pandemic. This high level of protection was our shield against serious illnesses like measles, mumps, and whooping cough – diseases that can lead to severe pain, hospitalisation, long-term health issues, and even death.
But here's where it gets alarming: this hard-won success is rapidly eroding. Post-pandemic, the proportion of fully vaccinated one-year-olds has been on a downward trajectory. In some regions, we're now seeing rates as low as a worrying 80%.
The consequences are already being felt. Whooping cough notifications have surged to their highest level in 35 years! Just recently, we've seen measles exposure incidents popping up in Sydney and regional New South Wales, impacting places like hospitals and a high school hall. We don't want to mirror the experiences of other nations; the United States has already hospitalised dozens with measles this year, and Canada has unfortunately lost its official measles-free status. An outbreak in London has led to hospitalisations and may even mean unvaccinated children have to stay home from school.
Why is aiming for high vaccination rates so crucial?
When a one-year-old is fully immunised, they've received protection against a range of serious diseases, including diphtheria, tetanus, pertussis (whooping cough), polio, hepatitis B, Haemophilus influenzae type b (Hib), and pneumococcal disease. This comprehensive protection is vital for achieving herd immunity. Think of herd immunity as a community-wide safety net; it's the point where diseases struggle to spread because so many people are immune. This is especially important for those who cannot be vaccinated, such as infants who are too young or individuals with compromised immune systems.
When 95% of children are vaccinated, even highly contagious diseases like measles have a very difficult time gaining a foothold in the community, effectively safeguarding both the vaccinated and the unvaccinated.
We're sliding backwards, and the numbers don't lie.
Analysis from the Grattan Institute reveals an unprecedented decline in fully vaccinated one-year-olds over the past five years. In the year leading up to September 30, 2025, only 92% of one-year-olds were fully vaccinated, a drop from 95% in 2020. What's more, the number of regions and suburbs meeting the national one-year-old vaccination target has plummeted from 56% five years ago to a mere 18% today.
And this is the part most people miss: the declines are disproportionately affecting the most vulnerable.
In areas that previously had the highest vaccination rates, the decline has been minimal, just 1.3 percentage points since 2020 (from an average of 98% to 97%). However, in areas that already had lower vaccination rates, the fall has been more than four times greater, a staggering 5.7 percentage points (from an average of 90% in 2020 to 84% in 2025). It's disheartening to note that almost no area has seen an increase in vaccination rates, and every state is experiencing sharp declines.
Some of the most significant drops in fully vaccinated one-year-olds include:
- Bankstown, Sydney: from 92.2% to 84.8%
- Keilor, Melbourne: from 95.8% to 88.8%
- Gascoyne, Western Australia: from 95.6% to 76.9%
- Nerang, Queensland: from 94.1% to 82.2%
- Barkly, Northern Territory: from 96.2% to 87.0%
- Meander Valley and West Tamar, Tasmania: from 92.6% to 83.5%
It's important to understand that there isn't one single type of community experiencing these low vaccination rates. They are found in both urban and rural settings, across different socioeconomic groups, and in every capital city.
So, what's driving this decline?
It's become significantly more challenging to get children vaccinated, and it's not due to a single cause. A comprehensive survey points to a combination of psychological barriers to acceptance and practical hurdles to access. The intense public discourse and misinformation surrounding COVID-19 vaccines have likely cast a shadow of doubt over childhood immunisation. In fact, nearly half of parents with unvaccinated children do not believe vaccines are safe.
However, practical issues are equally significant. One in four parents whose children are only partially vaccinated cite difficulty in securing an appointment when their child's vaccination is due.
Governments have a plan, but now they must act decisively.
Australia's federal and state governments acknowledge the need to address both these psychological and practical challenges. They have indeed agreed on a new national vaccination strategy for 2025-2030, which aims to rebuild trust in vaccines, bolster the immunisation workforce, leverage data for targeted interventions, and enhance accountability for achieving results.
The real test, however, will lie in the upcoming government budgets. These budgets must translate the strategy's intentions into tangible investments and concrete actions.
These investments should cover a broad spectrum, including:
- Public advertising campaigns to raise awareness and promote vaccination.
- Combating misinformation by understanding community beliefs, tailoring government communications, and empowering health workers to engage effectively with hesitant individuals.
- Modernising data systems to accurately track trends and direct efforts where they are most needed.
- Expanding vaccination delivery points, offering immunisation in more convenient locations such as workplaces, community centres, and even homes.
Crucially, we need more ambitious targets to prevent certain communities from falling further behind. This must be coupled with funding for local initiatives, designed to meet specific community needs and help them catch up.
Australia has a proven track record of achieving ambitious vaccination goals. Returning to pre-pandemic levels will undoubtedly be more challenging than reaching them the first time. Therefore, governments must step up, redouble their efforts, and ensure the protection of Australia's children.
