From what started as a neighbourhood garage sale in 2013, the World’s Biggest Garage Sale is revolutionising how Australians engage with dormant goods. Now a champion in the profit-for-purpose resale retail revolution,  we are expanding our model with retailers via our SaaS (stewardships as a service) model. Here we are leveraging a $15 billion opportunity to engage with leading retailers to realise a truly circular system by redirecting product returns from landfill through renew, repurpose and re-commercing strategies.

Customer Focus

Customer centricity (aka Love) has always been the key to our success as World’s Biggest Garage Sale when managing our ‘business to many’ market. Whether it be B2C by engaging with customers directly in our circular economy precinct who wish to purchase goods for personal use, or B2B by managing our supply partnerships or corporate customers with office fitouts, we remain focused on delivering an exceptional customer experience to grow our business.


As pioneers in the circular economy, our challenges surround the management of diverse products. We are transforming the Surprise Chain™ into a supply chain. Challenges for us surround realising the best management system to cater for both unique products with regular shipping schedules to our circular economy precinct, and also vast random shipments of standardised goods from leading retailers.


Effectively processing returns is an exhaustive process for any retailer. Through our partnerships and SaaS model (stewardship as a service) we’re able to not only realise the opportunity that lies in dormant goods, but activate product stewardship by capturing high quality returned products for recommerce to the customer, whilst reporting on metrics and data for our B2B partners, delivering outputs and outcomes for their own ESG and CSR initiatives.

Company Mission:

The overall mission of World’s Biggest Garage Sale is to be pioneers and lead the implementation of a true circular economy by embedding practices at a systems level, from Australian homes to global businesses. We do this with a profit for purpose approach to create a positive impact on people and the planet.

Here at World’s Biggest Garage Sale, we truly admire and are inspired by companies that make implementing sustainable practices easy for the customer by meeting them where they are. In particular, we are inspired by Goterra, The Great Wrap, Pleasant State and Better Packaging Co.
