A story of climate action and young people trying to save the world means something much more personal for up-and-coming actor Lakesha Grant.

The Australian Theatre for Young People and Auckland Theatre Company's presentation of Kim Chapman's show The Resistance, explores what happens when young activists are thrown into the national spotlight in the pursuit of change.

It's an exploration of friendship, ambition and the power of fighting for your beliefs welcoming audiences onto the stage in a real-life protest rally.

Ms Grant's character Bundilla, or "young" in Larrakia language; her dad's mob, is the communications director of the youth justice climate movement.

It's also the name of her great grandmother and a nod to something much bigger.

"The story is (about) trying to get the Prime Minister to sign the Athens climate agreement..to basically save the world," Ms Grant said.

"I think for Bundilla, it's a lot deeper than climate change. It's about caring for country, caring for Indigenous land…it's a lot deeper for her than it is for the other characters.

"It's not just about politics.

"It's, it's Indigenous people and that connection to the land. So you're really listening to us First People.

"I'm very much deeply connected to this character. These are conversations we have every day as First Nations people."

The Resistance is Ms Grant's biggest show to date for the 22 year old actor, after moving to Sydney from Darwin at 18.

She says her community and elders had always backed her to follow her dreams.

With a storyline centred around young activists, Ms Grant said it speaks to the responsibility and action of new generations.

"Older people can connect to it and understand that it's us young mob, we're the future.

"We have to take over now. It's our time to be the voice"

The Resistance runs until March 11 at Rebel Theatre in Sydney.
