Councillor Vanessa Keenan has placed forward a motion to call the emergency, which will be discussed at Monday's council meeting.

Herself as one of three councillors who attended the protest, she envisions Monday's meeting will host many heated discussions.

"What we have today in Wagga is a choice," Cr Keenan told Friday's gathering.

"I choose to act. I want to see council become a community leader on something that will be felt by every town, every city, every village in the world."

Also in attendance at the meeting was Wagga City Mayor Greg Conkey and Independent state member Dr Joe McGirr.

"Today is 17 degrees and tomorrow is supposed to climb to 18 degrees," Mayor Conkey said.

"That's extraordinary in the middle of winter in Wagga, so if that doesn't make people think twice I'm not sure what will."

Referencing next week's decision, Mayor Conkey spoke of rectifying the council's previous inaction on the issue of climate change.

"In 2008, council voted to halve its emissions by 2020," he said.

"Well, we have failed, in fact, we have doubled our emissions in that time."

Friday's protest was a culmination of attention from a coalition of medical professionals in the city.

Spearheaded by Dr Trudi Beck, it has so far consisted of a small weekly gathering outside the office of federal member Michael McCormack.

Another member of the so-called 'picnic protesters', Joanne Osborne has spent the past year writing letters to members of each level of government.

Friday's gathering and Monday's looming decision liberated her fears that she had been shouting alone in a vacuum.

"it gives me hope that so many people took time out of their busy days to be here, and to be at the premiere of [film] 2040, it was a sell-out," Dr Osborne said.

"I was expecting more opposition [from the crowd], but aside from a dog barking, there were no interruptions. I think that's representative of the groundswell of support that's developing."
