Fintona Girls' School Year 11 student Maiysha Moin will MC a demonstration on the steps of Victorian Parliament on Friday to protest inaction on climate change.

Maiysha Moin is not your stereotypical environmental activist.

She goes to a private girls’ school in the blue-ribbon seat of Kew. She rows – sport is a major part of her life. Her father is an associate professor, her mother a radiographer. Maiysha wants to be a doctor.

But, at midday on Friday, the Fintona Girls' School Year 11 student from leafy Balwyn will MC a demonstration on the steps of Victorian Parliament.

In what’s being dubbed the Big School Walk Out, students across Australia will skip class in protest against what they say is inaction on climate change.
