National Reconciliation Week is held each year from 27 May to 3 June, with these dates commemorating two significant milestones in the reconciliation journey — the successful 1967 referendum, and the High Court Mabo decision respectively. The theme for this year is Be a Voice for Generations , which encourages all Australians to be a voice for reconciliation in tangible ways in their everyday lives. Within CSIRO, National Reconciliation Week will be celebrated with a range of virtual and site-based events and activities.
