Tanya Kauter would know.

She couldn't wipe the smile off her face as she watched her 11-year-old daughter Bridie go bald in support of cancer patients and their comfort and care.

Joining her was a large crowd who refused to be put off by the pouring rain on Saturday for Bridie's Bald is Brave grand finale.

With Nabiac markets as the backdrop, people sheltered under umbrellas, the awning, or just braved the rain, cheering as each of Bridie's honey gold locks fell victim to the shears.

Holding them was Nerida Ramsay, her mother's best friend, café owner, former hairdresser and brain cancer survivor, who wiped away her own tears as she acknowledged the statement Bridie, a Year 6 Nabiac Public student, was making.

"I have personally benefited from staying where Bridie's fundraising is going, so it had come full circle, and being there shaving her head brought the emotions back from that," she said.

"I was a bit nervous about how Bridie would react afterwards. Year 6 is a big year! You don't realise how much as a female you are actually attached to your hair until you don't have it. But she handled it like a pro."

If Bridie was nervous, she didn't show it, smiling and joking her way through the shave.

Her peers and teachers reflected a spread across all the grades from 'the best little school anywhere', and they topped up the coffers for her fundraising campaign.

"It was very brave, I don't know anyone else who would do that. They would be too scared of how they look," friend and supporter, Archie Murray, said.

The diverse cross section of supporters also spanned her local soccer club Wallamba FC, the local netball club, Nabiac's social club, businesses, family and complete strangers.

It was a telling revelation about the depth of support a single selfless act of empathy can engender within a community.

"The support overwhelmed me, from people we don't know to people we do. Lots have shared their own experiences too. It's been amazing," Mrs Kauter said.

Bald in time for winter, a shinier Bridie bounced off her stool to accept a beanie to brave the cold and the future.

"I was so proud of her. It's such a vulnerable age, but she's so comfortable and confident with the way she is looking now, she's not worried about it at all," Mrs Kauter reflected, adding that in the lead-up she'd forewarned her daughter that she would have to accept the comments and stares she might attract.

"That's okay, Mum. I'll rock it!" Bridie had responded.

"She just wanted to do what she could do to help. In doing so, she's taught me that you should believe in what you feel, if you really want to do something, don't let anything stop you."

It remains to be seen whether her hair will be long enough for the charity Variety to turn into a wig, but Tanya is confident the funds raised have exceeded anything they had hoped for.

She will announce the final figure at the end of this week.

In the meantime, donations via Bridie Kauter's Bald is Brave campaign to Patient Comfort and Care at Calvary Mater Hospital will be accepted online until Thursday April 4.
