Unfazed by threats from Shoalhaven civic leaders, there was a strong presence of high school and primary school kids at a climate strike through Nowra on Friday.
Some Shoalhaven Councillors had shot warnings at students who left school to participate in a climate strike in March, saying their prospects may be impacted by an unexplained absence on their attendance record.
The students were not gentle in their rebuttal on Friday.
"Today we're here to protest the inaction of our government," Bomaderry High's Miette Hancox said.
"In their brains, 150 years of coal left in the entire Earth is long enough to put off our future, our children's futures and their own.
"Temperatures are rising, oceans are acidifying, our reefs are dying, we've already lost some of our small mammal species to climate change.
"The constant inaction and complacency of the powers that be and the federal government is absolutely appalling.
"The absolute cowardly men on our council like to stomp us down and minimise our efforts. There will never be a day where we won't go out kicking and screaming for our planet."
There were not as many students present at the May strike than in March.
"I can't believe some parents have told their children they can't come this time," organiser Bonnie Cassen said.
"Parents are thinking of their kids being silly little children protesting something, this isn't just a protest, this about their future and protecting the planet for everyone."
