Thousands of people, young and old, filled Launceston's Civic Square on Friday in an attempt to have their voices heard with cheers, speeches, and powerful placards.
The Launceston Strike 4 Climate was one of many rallies to take place around the globe, with millions of protestors all fighting for the same cause - the future of our planet.
Speaking to the crowd, Year 11 Scotch Oakburn student Ethan Hamilton thanked everyone for recognising that climate change was real.
"We need climate action, we need climate justice, and we need it now," he said.
"Summer is longer, summer is hotter, bushfire season is starting earlier and lasting longer.
"We can no longer live under that rock that we call ignorance when the ice is melting and the forests are on fire."
Anthony Houston of Houston's Farms told strikers he developed a strong bond with nature at an early age.
"I'm here because farmers right around the country are on the front line of climate change," he said.
"70 per cent of our food and fibre comes from this system.
"It is our job to stand up and lead and get others to stand up with us and make our voices heard so that the people in power can no longer ignore us."
A passionate speech by Year 12 Launceston College student Anna Roberts was also met with resounding praise and applause.
She said they had three demands - no new coal, gas or oil projects including Adani; 100 per cent renewable energy generation and exports by 2030; and, the funding of transition and job creation for all fossil fuel industry workers.
"It's not even that we want those demands. It's that we need them," she said.
"We have the evidence. We have the science, the numbers, the statistics, the facts.
"We simply cannot afford to not demand justice, demand action, demand change."
Tasmanian senator Eric Abetz was concerned about the students' involvement in the rallies, and claimed the attendance was only because the event took place during school hours.
Tasmania's Science Minister Michael Ferguson also had issues with the protests, and said people needed "to be alert" about the underlying message of immediate action on climate change.
"If the key messages from some of these protest movements were taken on board, we'd see a carbon tax, we'd see a hit to the economy and we'd be losing thousands of jobs including at Bell Bay," he said.
Children and Young People Commissioner Leanne McLean said young people cared deeply about the environment they live in, and were genuinely worried about the future impacts of climate change.
Ms McLean said those who striked sent a powerful message that combating climate change was one of their top priorities.
"They want to be engaged in the decisions that affect them both now and in the future, as is their right," she said.
Ms McLean hoped the state's decision makers, at all levels, should take the opportunity to stop and listen to the messages being conveyed at the strikes.
Climate strikes also took place in Hobart, Devonport, Burnie, Wynyard, Zeehan, Currie, and St Helens.
Former Australian Greens leader Bob Brown said the Hobart strike at Parliament Lawns was "bigger than the Franklin dam protest".
Organisers said about 22,000 people attended.
