Up to 500 people are expected to march through the city on Friday, making their voices heard for climate change.
Part of a national movement led by students, the climate strike will begin at 12pm outside the Fitzmaurice Street office of deputy prime minister Michael McCormack.
It will then progress down Morgan Street before looping back towards its point of origin in a circuit that is expected to last up to an hour.
Pat Murray, president of the Climate Action Wagga group, has volunteered to act as a marshal.
Despite the increased foot traffic through the CBD, the group said it is not anticipating to cause any traffic congestion.
"I'll be there to make sure we don't impede traffic on the way down Morgan Street and back," Ms Murray said.
Additionally, a spokesperson for Wagga City Council revealed on Wednesday that there have been no notifications of intention to close roads during the procession.
Though three protests of this kind have taken place in Wagga this year, Ms Murray believes this one holds the potential to showcase the widest spread of ages because it has been organised by environmental group Fridays 4 Change, in collaboration with local students.
Ms Murray said the age diversity was a necessary step in showing the city that the environmental message exists outside of generational divides.
"In some respects, I think the older generation sees what's happening and feel some sense of responsibility for it. We've been in the fight for a long time, but it's nice to be joined by new [blood]," she said.
Once the strike returns to Fitzmaurice Street, some of the activists are expected to address the crowd, and Ms Murray said she knows of at least two school students who will be among them.
"We might get 50 or 60 school students [at the rally], but it's hard to know," she said.
Last week, the NSW Department of Education revealed it would not support the strikes, and that "unexplained absences will be subject to the school's disciplinary code".
By contrast, Charles Sturt University announced earlier last week that full support would be given to any of its students in Wagga who wished to leave classes, assessments or exams to take part in the protests.
The university's declaration, along with the emergence of more climate action groups in Wagga, has provided necessary oxygen to the environmental cause, said Ms Murray.
"It's gaining momentum around the city now," she said.
It's given people the confidence to be able to say they're concerned about this situation, and hopefully, they won't be shot down so quickly.
"There's more discussion on this than there was a year ago."
