Project Raizes Brasileiras (PRB) leads community-based activities to address the issue of background language maintenance among stakeholders of Brazilian community in Brisbane. PRB understands that community languages maintenance is a collaborative work among children, families, schools, immigrant and local communities. Starting in 2016 as an independent project, Raizes Brasileiras expanded in 2017/2018, delivering Portuguese-language courses, cultural workshops for children, cultural community-based events, training workshops; involving a sum of 75 children, 10 educators, over 400 parents, numerous bilingual professionals, local businesses, performers, academic researchers, and incorporated associations. In 2019/2020, PRB expects to develop similar activities, reaching a superior number of participants and deliver a pilot prototype of didactic material for background language learners of Latin-American languages.
