Having taken to the podium during the strike last Friday, 17-year-old Lily Hamilton said the buzz has far from died among her peers at The Riverina Anglican College.

"People are still talking about it now, I think the strike really brought up the issue and eyes are opening up to it now," said the incoming sustainability captain.

"A lot of people have come up to me since and asked me how they can get involved with what I'm doing at the school.

"There's also been a lot who have asked me what's the point of it all, and even that is good because then it means I can tell them why it matters. It's all bringing attention to the issue, to this climate crisis.

"There's power in individual changes, even if it's just reducing your own personal waste, that makes a difference."

The students involved say they have received significant backlash both in-person and online for their participation in Friday's strike action.

Most notably, they say they felt disheartened hearing comments made by both the prime minister and deputy prime minister.

In response to a speech made by 16-year-old Swedish climate activist Greta Thunberg earlier this week, Prime Minister Scott Morrison said that he felt the climate strike promoted unnecessary concern among young people.

"I don't want our children to have anxieties about these issues," he said.

"We've got to let kids be kids."

But 17-year-old Bridget Elliott-Rudder, who became the informal face of the strike in Wagga last week, said his comments misrepresent the maturity of youth voices.

"Scott Morrison said it wasn't the best thing for us to be doing, and I'm told Michael McCormack said we shouldn't be out there disrupting things during the school week," she said.

"I think that's an inconsiderate thing to say because this is our future. It's mine and it's the younger generation that comes next that will have to deal with this.

"We're just trying to do anything we can to make a difference, and they're not listening."

Charles Sturt University Green group leader, Ed Maher agrees with the student's sentiments, saying that the point of the strike was to provide agency to a part of society that often feels unheard.

"[Children] have a role to play here, and from what I saw out there, the ones who were getting involved were aged 16, 17 and 18, they were the most represented," he said.

"That's the age group that's emerging as adults, they are aware of the issues and making decisions that will make a difference.

"It's important and appropriate to give them a platform - they don't have many - so that they can say to leaders safely and peacefully that this is of concern to them."

Ahead of the strike last week, the NSW Department of Education announced it would not overtly support the involvement of its students.

Instead, it would leave any potential punishment for absenteeism to the discretion of individual schools.

Bridget Elliott-Rudder acknowledged the threat but said the potential punishment was not a deterrent from her involvement.

"Before the strike, we had been told that we shouldn't wear our uniforms, just in case it reflected badly on the school," she said.

"I chose to wear my school uniform because it was a school strike after all, and I wanted to stand up for others in public schools."

Despite the forewarning, Bridget received only a stern talking to when she returned to school.

Likewise, both she and Lily say they have not heard of any students receiving punishment for their involvement in last week's protest.

"No-one I've spoken to has gotten into any trouble [from their schools] for being at the strike," Lily said.

"I think some schools had so many turn out that it would have reflected badly on them if they had suspended or punished them all," Bridget said.
