Launceston parents and students are concerned following reports of strangers approaching children at some of the city's schools.
Tasmania Police said a report had been made of a old red vehicle being driven near children walking along a footpath in Prospect earlier this month.
Police have spoken with the driver and investigations are continuing.
A report was also received about a man allegedly filming children near a Launceston school, with police continuing to make inquiries.
Education Minister Jeremy Rockliff said he had been alerted to the concerns of parents.
"And of course as a parent myself I would be concerned," Mr Rockliff said.
"All our schools ensure the safest possible environment for all of their students, and that's the number one priority.
"I understand some of the matters, as they are outside of the school, are now the responsibility of Tasmania Police."
Mr Rockliff said he urged vigilance within the community.
A Department of Education spokesperson said all schools placed the highest priority on student safety, and took all possible measures to ensure that students were provided with a safe and supportive environment.
"Schools promote 'stranger danger' awareness messages amongst students regularly, as well as ensuring student safety reminders for parents and carers regularly feature in school newsletters and communication," they said.
"Schools work together with their school communities to emphasise the importance of self-protective behaviour and personal safety messages, including avoiding approaches by strangers.
"Students should always be aware and alert, and feel confident that they can report any issues whenever they feel unsafe."
