MENAI High School raised its biggest amount ever this year for the World's Greatest Shave.
Students and teachers raised more than $17,000 for the Leukaemia Foundation.
One Australian is diagnosed with a blood cancer or a related blood disorder every 46 minutes.
The foundation supports thousands of people and their families each year by providing practical services at no cost.
These services include information, emotional support, transport and accommodation for regional families required to relocate closer to metropolitan treatment centres.
The foundation also invests millions of dollars each year into research to improve treatments and find cures for blood cancer.
Menai High ranked as one of the top participating schools in Australia for the World's Greatest Shave.
Sam Holloway was among several students who braved the shave, while Katy Armson-Graham, Imogen Boughey and Chloe Traynor gave one of the school's alpacas Othello a fresh look.
