A group of more than 500 students and parents from Castlemaine travelled to Melbourne to take part in the School Strike for Climate protest.
The group, which included the Mount Alexander Shire Mayor Bronwen Machin, boarded early train services and six special Vline coaches to the city.
They met outside The Age offices near Southern Cross Station and marched down Collins Street to the Old Treasury Building, where more than 25,000 people were congregated.
Castlemaine Secondary College Year 12 student Charlie Bell Willcox helped organise the Castlemaine group.
"Once we got down to the Old Treasury Building it was just amazing," he said. "We listened to speeches of students from all around Australia and then marched through the city."
"There were that many of us, it took us 10 minutes to pass from the start to the end," he said. "It was massive."
Mr Bell Willcox attended the last national strike in Melbourne.
"I originally thought it would be the same size as the one in November," he said. "But upon arriving, there were at least double than at the last time.
"It wasn’t just a school strike," he said. "There were a lot of primary and high school students, plus also parents there in solidarity."
There is currently not another strike planned but Mr Bell Willcox said the students won't stop marching until the government takes action on climate change.
"We will keep fighting," he said.
