Almost 200 people from the New England region rallied together at the Tamworth Town Hall to highlight the impacts of climate change.

Participants had four key demands: 100 per cent renewable energy by 2030, no new fossil fuel projects, funding for firies and First Nations justice. A just transition for fossil fuel workers is also at the top of the agenda.

The demonstration was part of the Climate Crisis: National Day of Action, which will see events taking place across the country.

"The science, which is now indisputable, tells us we need to act immediately to prevent the worst foreseeable impacts of climate change," organiser Tessa Rainbird (Tamworth Parents and Friends for Climate Action) said.

"There are so many people in New England who care deeply about this issue, who are increasingly speaking up."

"For me, it is about the children. Having to keep my baby inside for days on end due to bushfire smoke this summer set the alarm bells ringing. I see it as a crucial part of my role as a parent to push for needed change," Ms Rainbird added.

Mr Morris made international news headlines in 2016 when he rode a horse across the Sydney Harbour Bridge to raise awareness of climate change.

"After spending 20 years researching solutions and taking action to fight climate change, I know the greatest need we have is ethical leadership with a solid vision for our future. With the help of nature, restoring a beautiful healthy earth is possible," Mr Morris said.

The demonstration was a collaboration between environmental advocacy groups in Tamworth, Armidale and Inverell.
