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 delivering grassroots initiatives supporting vulnerable members of our community including children, the elderly, the homeless and people living with a disability.

To date, Impact100 SA members have contributed more than $1 million, transforming organisations and supporting 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 once a year to vote in a democratic process that determines which organisations are awarded the high impact grants.


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

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 Management Committee.
