Georgia, who turned 17 years old during the week, had her head shaved at the Old Collegians clubrooms on Saturday night in front of a crowd of about 160 supporters.

She had hoped to raise $5000, lifted her sights during her fundraising campaign for the Cancer Council of Victoria to $15,000 after overwhelming support and then finished with about $19,500.

"It was very cold last night," Georgia said on Sunday.

"I'm looking in the mirror now and it's nice and fluffy," she said with a laugh.

Georgia said she was surprised just how much money was raised.

"My uncle Gerry Billings said he would put in $1000 if he could shave my head. I was a bit worried about him," she said.

"But, he did a good job. There were a few people who helped shave me. It was a great night.

"I would just like to thank everyone who supported this great great cause and all the businesses that got behind me. I've put up a list on the Facebook page thanking everyone.

"I was a bit worried about having my hair shaved off but would encourage anyone who is thinking about it to have a go. You can raise some money and that could all help people in future."

Cancer has touched Georgia's family a number of times, which prompted her fundraising efforts.

Her long blonde hair will be donated to provide wigs for people receiving cancer treatment.
