Members have raised nearly $2500 as part of this year's Movember, contributing to the nearly $15,000 across the Wagga region.

The members will face the big shave at 12pm tomorrow.

As part of the day, the shed will open at 11am and there will be various activities for attendees to raise more funds for the cause.

These will include tours of the fire trucks and throwing sponges at firefighters.

Brigade captain Matthew Paton said everyone had been supportive.

"It's the first year we've done it, we didn't set a goal and just tried to get as much raised as we could," Mr Paton said.

Asked about whether he looks forward to shaving it off tomorrow, he said it did not worry him too much.

"I usually have a mow anyway," he said.

Brigade member Petrina O'Connor said this year's response had been "really good".

"We didn't initially think it'd be taken this far [with having an event tomorrow], but we did based on the amount raised," Ms O'Connor said.

"There will also be a smoke house to let the kids know what it feels like to be surrounded by smoke.

"The atmosphere would be like a fete."
