Our Story

At Impact100 SA we use people power to improve the quality of peoples’ lives. By pooling $1,000 donations from at least 100 members annually, we’re able to award high-impact grants to a range of South Australian-based organisations each year. These organisations deliver grassroots initiatives, supporting vulnerable members of our community including children, the elderly, people experiencing homelessness and people living with a disability.

Funding provided by Impact100 SA members has transformed local organisations and supported them to step up to a new level, expand their services and underpin their sustainability.

Our generous members have a direct say in where the money goes, coming together to vote in a democratic process that determines which organisations are awarded the high-impact grants.


All donations are tax deductible and your full $1,000 donation goes directly to the chosen organisations—there are no administration fees or commissions taken from your contribution.

Impact100 SA is a sub-fund of the Australian Communities Foundation and incorporated under the Associations Incorporation Act 1985 in South Australia.

The day-to-day running of the Impact100 SA model relies solely on a voluntary Management Committee and specialised subcommittees. Click here to meet our team of passionate people.
