It was a close shave in the Movember Games at St Phil's on Thursday, with the students beating teachers by just one point.
Now in its sixth year, the games are a fundraiser devised by the school to support the Movember Foundation, which raise awareness and money for men's health.
Year 2 teacher and Movember Games coordinator Jacob Parslow said the day was a highly anticipated annual tradition on the school's calendar, and is loved by both students and teachers alike.
He said he founded the games in his first year at the school, and Movember, and all it stands for, is an charity supporting issues which are close to the school's heart.
Mr Parslow said the games were a much loved but fiercely competitive event, evident by the fact the students won this year's games by just one point.
"It's a great chance for the Year 6 students to get any grudges they have against the teachers off their chest," he laughed.
The students went up against the teachers in three sports; soccer, rugby league or volley ball, with the Year 6 students split up into three teams.
Each group went up against a team of teachers and then tried to outplay them.
Points were earned throughout the games and added up at the end, with trophies then awarded.
After the final whistle on Thursday, the students took out the title, with 41 points.
Mr Parslow said the kids really enjoyed the day.
"The whole school comes out and watches," he said, adding all the kids had spent the last week making their moustaches at home, in readiness for the day.
While fundraising figures were yet to be finalised, Mr Parslow said every year the event raises between $200 and $300 dollars, which is then donated straight to Movember.
Movember is an annual event involving the growing of moustaches during the month of November to raise awareness of men's health issues, such as anxiety, prostate cancer, testicular cancer and men's suicide.
