On March 5, Ms Paull, Katherine South Primary School's administration manager, will be shaving her head to raise funds for the World's Greatest Shave.

The selfless pledge is a tribute to the well-known Bryant family, who found out their three-year-old son had leukemia last year.

In less than a week she has raised $1361 and brought on an additional school teacher to raise the stakes. If Katherine can raise $3000, Rachel Jay, will also be getting the chop at the school's assembly in just over two week's time.

"I've always wanted to do it, but the couple of times I've come close the kids here at [Katherine South Primary School] had beat me," Ms Paull said.

"I lost my hairdresser this year as well, and given the Bryant family is going through this really tough time with their youngest boy, it feels very close to home.

"It has really touched everyone in the school and the community."

Anica Bryant is a pre-school teacher at Katherine South Primary, but when her son was diagnosed she had to uproot her life with her family so he could receive life-saving treatment far from home in Adelaide.

The feat has since been on the minds of Katherine at large, culminating in massive fundraising efforts.

Last year, Katherine youth Felicity Brown, sparked a town-wide event which lead to tens of thousands of dollars being raised for the family.

Hundreds of people gathered at Rod and Rifle Camping and Fishing store on September 12, digging deep into their pockets.

"People were donating at least $100," Rod and Rifle owner Trent de With said.

"I've never seen anything like it before, it was the biggest pool of community spirit."

Ms Paull says she wants her fundraiser, to reach at least $2500 - and when it happens she won't be going in lightly.

"My husband asked if I was going to do a number four, but that's not shaving. It's completely going," she said.

"We don't have the facilities [in the Northern Territory] to deal with these cancers and the expenses to go interstate for treatment must be through the roof.

"This is the least I can do. Hair grows back. We can't be precious about our looks."

For Ms Jay, she is on board to up the ante and encourage more money for the charity, which helps fund researchers searching for a cure and families dealing with the hardship of cancer.

"I was talking to my husband about how quickly the money was going up. It has impacted the school and the community in a very big way," she said.

"He suggested that if Jacqui reaches $2000 I should dye my hair."

However, in a rapid change of events unbeknownst to her partner - yet - Ms Jay has taken her pledge a step further.

"If Jacqui can get to $3000, I'll shave my head too."

The shave, at the hands of local hairdresser Natalie Angove, is expected to take place at the school's morning assembly on March 5 - a matter of days before the annual picture day.
