Rochester Secondary College Vocational students Jack Mundie and Caitlin Quinn are leading this year's event, taking on the role as part of their hands-on social enterprise studies.
Teacher Kate Taylor said the garage sale was a chance for students to learn about community involvement while putting their skills into practice.
“I’m a big advocate for my students to, if they can, learn by doing rather than learn by sitting in the classroom,” she said
“The two students organising it ― they're absolutely kicking goals and doing a great job.”
The event was previously run by Rochester Community House, but as it grew in size and demand, the Vocational class stepped in to take the reins last year.
More than 60 households took part last year, with registrations already attracting interest ahead of this year’s event.
Registrations will be taken at Rochester Community House on October 6 and 13 from 10am to 2pm.
Once registered — whether you're selling from your own property or setting up a car boot stall at the silo site — you'll be included on a town-wide map handed out to shoppers on the day.
The registration fee covers the cost of signage and other materials provided to participating households, with profits donated to a charity or community group chosen by the students.
Ms Taylor said the event was a win-win — giving locals a chance to declutter while drawing visitors into town for the day.
With shoppers browsing garage sales and popping into local cafes and shops along the way, the event gives the whole town economy a welcome boost.
For those wondering what treasures might be waiting at Rochester’s garage sales, Ms Taylor said the event had already attracted interest from visitors planning to attend other town-wide sales on October 31.
“There must be some good stuff floating around Rochy,” she said.
