We all have things we don't need. For Canberra resident Zoe Bowman, it is melon ballers. "Someone asked for a melon baller to make some melon balls for a kid's party, and I looked in the drawer and I had three," she says. "I don't need three melon ballers!" The request was made on a Facebook page that she manages, one of the thousands of local pages that make up the "buy nothing" movement. Part zero-waste movement, part community-building project, "buy nothing" has taken off in Australia's affluent inner-city suburbs as a way to rehome unwanted goods and avoid unnecessary purchases " like a third melon baller. The "buy nothing" project began in the United States as an attempt at creating a cashless economy. The aim was that communities would distribute goods according to need, which meant group members had to explain why they needed a particular item in order to receive it. It was a slightly problematic beginning, says Bowman, and the secret Facebook group where "buy nothing" page admins gather has since gone through a decolonisation and anti-racism process that led to it losing some of its original fans. In Australia the tone is lighter but the rules remain. Giving an item away to the first person who replies, like you would on a buy/swap/sell page, is far too transactional for the "buy nothing" community. "The whole aim of the thing is actually community building, not getting rid of stuff," Bowman says.
