How Impact100 SA works

Impact100 SA brings together at least one hundred members who each donate $1,000 annually. Their contributions are pooled to make high impact grants to South Australian-based charities or organisations. Winning charities are collectively voted by members at an annual Grant Announcement Evening. Donations are fully tax-deductible with the full amount reaching the winning charity. Impact100 SA is a sub-fund of the Australian Communities Foundation.
