Scots School Albury year 12 student Luca Lamond said a number of adults including each of the Border's deputy mayors were attending to show their solidarity.

"We're expecting around 1000 - that has been the trend with the last few strikes, in that they are doubling each time," he said.

"I think we might be the biggest (strike) outside of a capital city, which is awesome, and especially important since Sussan Ley is the Environment Minister."

The committee has been told Ms Ley is away in Darwin on Friday, but Eli Davern, 15, of Xavier High School said a petition would be presented to her office.

"It's Sussan's job as our elected official to listen to our concerns, and now as Environment Minister it is her duty to take care of our environment," he said.

"I think it's really important for ScoMo (Scott Morrison) to really be thinking about his legacy.

"Because at the rate we are going through Prime Ministers, his time is almost up, so does he want to be remembered for leading the way forward for a sustainable future, or does he want to keep producing these dirty fossil fuels that are going to ruin the planet?"

Eli hoped public schools would come out with their support of the strike, like the Border's universities and community representatives.

"We've got lots of kids from Albury High who always come down because they really care," he said.

"But it's difficult for the schools to support them ... they can't take a stand on political issues.

"It's not a political issue, it's a moral issue.

"We've had good support from police in recent weeks and members of council."

Xavier High School assistant principal Lorraine Willis said the school was supporting students who wanted to attend and the position was the same for Scots' deputy principal David Armstrong.

"We moved obstacles out of the way to let them see through what they have envisaged," he said.

"I've got lots of staff volunteering to help out with supervision; not so much for the older students, but we've got kids as young as 12 who have signed up with their parents' consent."

Among the community members joining Border students on Friday will be Parklands Albury-Wodonga rangers.

Board chair Daryl Betteridge said a motion was passed at Tuesday's board meeting to encourage Parklands staff to attend.

"This to us is empowerment of young people in our community," he said.

Deputy mayor Amanda Cohn has supported the group in going through the official checks with Albury Council.

"I'm very proud to have supported them, and I think from Albury Council's perspective, it's really about safety - there's going to be hundreds of young people striking and crossing the road," she said.

Wodonga deputy mayor Kat Bennett said young people, often unfairly seen as apathetic, should not then be discouraged for showing passion and taking action.

"They're doing this in a really organised, safe way, and striking and demonstrating is the backbone of democracy," she said.

They are joined by Wangaratta councillor Ashlee Fitzpatrick in voicing their support for the rally, at the request of former Independent candidate Jacqui Hawkins, who said; "If not you, then who, and if not now, than when?"

The Albury addition to the Global Strike for Climate will run from 11am to 1pm at QEII Square.
