The Victorian health department is advising people to monitor for meningococcal symptoms after a case connected to schoolies celebrations in Queensland.
An 18-year-old has been diagnosed with the disease after celebrating in Maroochydore, on Queensland's Sunshine Coast.
The department is advising people who attended social venues in Maroochydore between November 26 and December 2 to be alert to meningococcal symptoms and to act immediately if they appear.
Symptoms include sudden onset of fever, headache, neck stiffness, joint pain, a rash of red-purple spots or bruises, sensitivity to bright lights, nausea and vomiting.
Victorian deputy Chief Health Officer Deborah Friedman said people should immediately seek medical attention if they suspected symptoms of the disease.
"Early treatment for meningococcal is life-saving," she said.
The department said children under the age of five and people between the ages of 15 and 25 were at greatest risk of contracting the disease, though it could affect all age groups.
Children might experience non-specific symptoms like irritability, difficulty waking, refusal to eat and high-pitched crying.
"The close contact between young people at events like Schoolies might have placed them at increased risk of contracting this infection," Dr Friedman said.
The department said meningococcal infections were uncommon thanks to vaccination.
Fourteen cases of the disease have been reported in Victoria so far this year.
Two people from New South Wales died from meningococcal after attending music festivals earlier in the year.
"Vaccination remains the best way to protect yourself, your loved ones and the community from the harmful effects of meningococcal disease,' Dr Friedman said.
The disease is caused by strains of bacteria found in the upper respiratory tract and can spread from person to person through close or prolonged contact.
