The 1969 students of Ballarat High School have a motto they share among themselves, says former student Judith Jhureea.
"What we say to each other is: don't pretend to be something you're not, as we all know where we came from, where we started," she says.
Ms Jhureea has been gradually bringing former students of BHS together over the the past few years.
"I've found ex-students recently, and when I would go to Melbourne for a visit, I started saying, 'I'm here: who wants to meet up.? So it kind of snowballed from the first meeting of 10, then 20 and so on," Ms Jhureea recalls.
"But this is the big one - 50 years!"
A planned meeting with the current headmaster of Ballarat High at 1pm on Saturday begins a weekend of recollections and reconnections for the former students.
A dinner in the Marble Lounge of the Lake View Hotel has been booked for Saturday night at 6pm, and Ms Jhureea says already she has 57 people booked.
Sunday morning is a morning tea (and recovery for those who go a bit too long reminiscing on Saturday night) at Pipers on the Lake, she says.
"Some of us haven't seen anyone for over 40 years," says Ms Jhureaa, who has been a stalwart in reconnecting the students.
"For a lot of us it would be 25 years. At least 30 of us meet up twice a year; we all really enjoy reconnecting. Many of us have rediscovered old friendships or started new ones."
Any former students who wish to attend can contact Judith Jhureea on Facebook.
