Three staff members from the Bowral branch, Trudy, Bonnie and Mikhael and the NAB area manager Paul Thornton decided to get involved with World's Greatest Shave after the disease touched too close to home.

"All of us have had issues with cancer," Mikhael said.

"I lost my father, Bonnie lost a family member with Leukemia and the NAB staff has lost several members to various cancers."

Mr Thornton said he was participating in World's Greatest Shave because his best friend was diagnosed with Leukemia three years ago.

"He's come through it and the Leukemia Foundation really supported him," Mr Thornton said.

Mikhael said he was proud to participate in the World's Greatest Shave with his three colleagues.

"It's easy for a guy to go bald, but I'm so proud to have my two colleagues on board as it's so hard for girls to have that sort of cut," he said.

"If the funding doesn't come from people like us and people who donate to us, where will the cure really come from?"

To top off fundraising efforts, there was a barbecue and cake stall out the front of the NAB on the day run by branch manager Kim Cross and staff.

"Kim has been very supportive and has allocated time and resources to make sure it happens and Karen and Michelle came in on their day off to help," Mikhael said.

The group raised more than $5000.

Mikhael said they hoped that finding a breakthrough with one kind of cancer would lead to a major breakthrough in all cancer research.
