IT started six years ago as a breakfast attended by three dads — now it caters for 500 people.
The Bidwill Blokes Breakfast has live music performed by students, and car, reptile and emergency services displays among its attractions.
"Superman" hosted the Chifley College event, held at the school's Bidwill campus, which aims to celebrate male role models and create links between the school and community.
Principal Mark Burnard said while the focus was still on "blokey" activities such as woodturning, cars and an adrenaline-inducing rock climbing wall, the event helped to develop communication with the parents of students.
"It grew out of our interest in boys' education and wanting to encourage more dads to be involved in their boys' learning at school," he said.
"It has developed in different ways. What I'm most proud of is that everybody loves the event."
Jason Gardner attended the breakfast with his twin sons Aiden and Jacob, 14.
He said the sausage sizzle breakfast, wall climbing and tractor rides were highlights.
"I think it's a great community event," he said.
"I've been here for the past couple of years and it's just getting bigger and bigger.
"There's always a good show of cars, with more and more hot-rods and bikes here every year.
"It shows a bit of support for the boys as well."
Aiden and Jacob are part of school project which has seen them restore a T92 Ford Falcon.
"They've learnt how to change spark plugs, do diffs, check tyre pressures and oil, all the things they're going to need to know when they get out of school," Mr Gardner said.
"It's stuff that seems to go by the wayside now with the younger guys."
