On Friday, September 20, students, workers and community members around the globe will join together and strike for more action on climate change.

The march coincides with the United Nations Emergency Climate Summit 2019 on September 23 in New York.

The strike in Port Macquarie will begin at the Glasshouse forecourt and end at Cowper MP Patrick Conaghan's office.

Theo Last, Ivy Moore and Patrick Rudd are three young leaders who were instrumental in the local Schools Strike 4 Climate.

They say the previous Schools Strike 4 Climate marches have been leading to this global march.

"The general strike on Friday is to engage the whole community in fighting for more action on climate change," Patrick said.

The School Strike 4 Climate Action movement was inspired by Swedish student, Greta Thunberg, who started boycotting classes before parliamentary elections in her nation on September 9, 2018.

Theo said it was encouraging that businesses and educational institutions have come out publicly and said workers and students will not be punished for striking.

"The criticism we received at previous marches was that we (students) should do it on the weekend or after school," Theo said.

"But this is bigger than students and it is great that businesses have come out in support of the strike.

"We are the closest we have been to extinction since the Cold War and yet despite climate change being worthy of extreme concern what action have we seen from our government? Nothing but frivolous measures."

The march will start at the Glasshouse forecourt at 9am.

Ivy said everyone in the community should come and march and continue to put pressure on government.

"It is so amazing that local businesses have come out in support of the strike action because it gives you hope that things might change," Ivy said.

"The strike is to encourage governments across Australia and the world to do more to stop anthropocentric climate change."

Co-founder of Australian Parents for Climate Action Port Macquarie, Suzie Brown said the march was necessary.

"Teenage school students started these strikes last year as they fear for their own safety in the face of rapidly escalating climate change," Ms Brown said.

"We parents all have young children who are too young to understand the climate crisis so we need to stand up for their safe future on their behalf. Joining the climate strike is one way we can do this."

Charles Sturt University's acting vice-chancellor Professor John Germov said the University supported the right of students and staff to take part in the protests.

"No Charles Sturt student or staff member will be penalised by the University for attending the events, which are an admirably peaceful and powerful way of advocating for much-needed action to address climate change," Professor Germov said.

"Charles Sturt has a long and proud history of dedication to meaningful action on climate change and sustainability.

"As a university committed to the public good and creating a world worth living in, these values continue to inform our programs, policies and initiatives as we strive to make a positive impact on the environment."

Sarah Mollard is a Port Macquarie GP and parent and championed the whole community to get behind the strike.

"Parents in our region are deeply concerned about the impact of climate change on our community, such as more frequent and severe droughts, more bushfires and heatwaves," Ms Mollard said.

"We need emergency action from politicians at local, state and federal levels so that we can limit these impacts on our community and protect our children's future.

"We call on all adults in the Port Macquarie region to stop work and join the strike on the 20th September - it's not enough to leave it to the next generation to fix this - we all need to act now."

The Global Climate March will begin at the Glasshouse forecourt from 9am on September 20.
