A sharp rise in measles cases across Australia has reignited concerns among health officials, with young children most affected.
Public health experts are urging stronger vaccination efforts to curb the resurgence, which has been linked to post-pandemic travel and declining immunisation rates.
According to the Australian Department of Health and Aged Care, 46 measles cases have been reported in the country this year, with 11 in NSW linked to returned travellers.
Health authorities have warned that these imported cases are triggering local transmission, placing unvaccinated individuals, particularly young children, at increased risk.
University of Wollongong paediatrics specialist Associate Professor Melinda Glover has described the current trend as “deeply concerning.”
“Measles is not just a mild childhood illness; it’s a serious disease that can lead to complications like pneumonia, encephalitis and, in some cases, death,” Ms Glover said.
“We’re seeing the highest case numbers in children under five, who are especially vulnerable, as well as adults in their mid-20s, a group that often misses out on full vaccination coverage.”

Data from the past decade highlights a significant increase in measles cases since 2022, coinciding with the easing of international travel restrictions. The youngest age group, 0-4 years, has seen the highest infection rates, raising alarms about gaps in early childhood vaccination coverage.
Despite the availability of free measles vaccinations for those born after 1966 who have not received two documented doses, experts fear complacency is contributing to the outbreak.
“Many Australians underestimate measles because it was nearly eliminated here decades ago,” Ms Glover said.
“But in recent years, we’ve seen rising cases due to global outbreaks, vaccine hesitancy and missed doses during the pandemic.”

In a public health warning NSW Chief Health Officer Dr Kerry Chant urged Australians to check their immunisation records, particularly those traveling overseas.
“Two doses of the measles vaccine provide about 90% protection,” Dr Chant said.
“It’s crucial that people ensure they’re fully vaccinated before travelling and that parents prioritise childhood immunisation.”
Ms Glover also pointed to the need for stronger public health messaging.
“While NSW Health has been proactive, we need to see more targeted campaigns aimed at young parents and under-vaccinated adults. Vaccination should be as accessible and routine as getting a flu shot,” she said.
With Western Australia also issuing measles alerts following an outbreak inside a Perth prison, experts have warned that ongoing vigilance is necessary to prevent further spread. Health authorities continue to stress the importance of timely vaccination, especially for children and unvaccinated adults, to prevent future outbreaks.
