Schools students will take to the streets in their thousands on Friday calling for more action on climate change.
But senior government minister Mathias Cormann has warned against "professional" adult activists "using and abusing kids" for their purposes.
The Australian reports that the planned student walkout School Strike 4 Climate Action is being backed by the Australian Youth Climate Coalition, a not-for-profit registered charity.
Senator Cormann said reports that adults were using students for their advocacy purposes were concerning.
"They should not be used as pawns by professional adult activists as part of a cynical political strategy," he told Sky News.
"Australians will take a very cynical view of professional adult activists using and abusing kids for their purposes during school time."
"During the school time kids should be in school."
Tens of thousands of school and university students are expected to miss school on Friday in the climate strikes.
School 4 Strike 4 Climate Action says it is movement of students from cities and towns across Australia.
However, in a press release it states this year students have opened the invitation to everyone including the union movement, health groups and the faith community to show solidarity with them.
The mass protests have divided opinion among political leaders with some backing the strike and others saying students should remain in school.
NSW Education Minister has warned students missing school in strikes campaigning for more action against climate change would be breaking the law.
NSW Education Minister Rob Stokes said the law is clear that school students must attend on school days.
"The law is clear and always had been, kids are required to be at school on school days," he told 2GB.
"Turn up to school. Don’t rob yourself of the opportunities to get a great quality education.”
In the lead up to student climate strikes, Prime Minister Scott Morrison called for "more learning in schools" and "less activism."
On Thursday, the Prime Minister again said students should stay in school.
"I always think kids should stay in school," he told ABC Radio.
"I'd encourage them to see ... I've set out in some detail how we meet our 2030 emissions reduction target of 26 per cent."
While, opposition leader Bill Shorten said students should protest outside of school hours, rather than during them.
"Kids are allowed to have an opinion," he said.
"In an ideal world, they would protest after school hours and on weekends."
But NSW Opposition leader Michael Daley is supporting the thousands of Australian students striking from school.
He backed the students planning to walk out of classes this week and rally for action on climate change describing them as "future leaders".
"They are inheriting from us a world that is, at best, precarious," the opposition leader told the National Press Club in Sydney.
"They don't have a microphone and they don't have money like the big end of town. But they do have a right to protest."
In response, NSW Premier Gladys Berejiklian said suggestions students should miss school to strike were "concerning."
"Children are there to go to school and I absolutely support their rights to have views about the world and I absolutely support them expressing themselves but not during school," she said.
"It really concerns me that the alternate premier to the state would think missing school is acceptable."
"The best opportunities anyone can have is to be at school and learn."
Labor leader Michael Daley on Wednesday said global warming was the most pressing environmental threat of our time and young people should insist on having a voice where they currently have none.
"I support these young people and their action," Mr Daley said.
"It's a demonstration of young leadership. Events such as Friday are formative for our future leaders."
Senior government minister Christopher Pyne said students were “damaging their education” by attending the protest.
“Usually strikes are when employees withdraw their labour from an employee so I’m not sure why the students are withdrawing themselves from school. It only damages their education,” he told Channel 9’s Today.
He said the government was acting to address climate change.
“It’s been happening for millennia, ever since the world was created and we are acting on it.”
