Mirella is keen to share her skills to support the organisation’s work, especially on the First Nations and International fronts. She also aims at gathering more critical knowledge and sharing with her Brazilian comrades in the jungle, as a way of fostering their food sovereignty too.

Rob Arcidiacono
Rob Arcidiacono
Rob Arcidiacono (he/him) is passionate about food and agriculture, a connection fostered growing up as the son of an Italian migrant who emphasised the cultural significance of food, and through his family’s ties to a fourth-generation farm in Stanthorpe, situated on the unceded lands of the Kambuwal people. Rob’s exploration of food sovereignty began in university and continues to be both a theoretical and practical foundation for his work. Connecting dimensions of Indigenous knowledge of land stewardship, social and ecological justice, and a critical lens on the industrial food system, and the broader implications these have on rural development in Australia and globally.
Rob has contributed to participatory research projects into Community Supported Agriculture (CSA) initiatives in East Africa, climate change mitigation efforts that empower artisans in decision-making in Afghanistan, and refugee support projects in Syrian camps in Jordan. More recently, his PhD research focused on the perceptions of agroecology-oriented farmers in Australia toward digital and data-driven technologies. His work amplifies the voices of smallholder farmers, often marginalized in national agricultural policy and decision-making, and critiques the dominant narrative around ‘ag-tech’ that perpetuates the unsustainable business-as-usual approach to addressing ecological and social issues in the Australian food system.

Antoine lives in Naarm and has a background in international trade and foreign languages, development economics, sustainable tourism and logistics.

Through his travels around New Zealand and Australia, Antoine developed a keen interest in agroecology and its potential to not only regenerate land and biodiversity, but also to tackle social and economic inequalities, climate change and current power dynamics in the food system. He’s been involved in hands-on food systems transformation for the last 8 years and keeps a keen interest in food systems and peasant literature, with a focus on agroecology, land reform and alternative distribution networks.
After navigating the values-based short supply chains of Sovereign Foods and Food Connect in Meanjin, and serving on AFSA’s National Committee since 2023, Antoine has now joined our ranks as General Coordinator while continuing his work at The Community Grocer, a not-for-profit food enterprise based in Naarm.
