New Members

If you’re here, then someone you know has invited you to become a member of Impact100 SA… welcome!

We are a giving circle that pools the generous donations from our members to create high-impact grants. Each year we give away the entire pool of money to organisations that are selected by our members… that could be you.

A donation of $1,000 will give you the right to vote at this year’s Awards Night (in October) where we will be giving away over $250,000!

If you choose to join us, you’ll be making a tangible difference to the lives of fellow South Australians. By contributing to Impact100 SA you are helping create grants that fund significant and transformative new projects and empower local organisations.


“We love being a part of Impact100 SA. Having the opportunity to hear directly from the charities we’re voting for, allows us to feel truly connected to the causes we’re supporting. We love that we get to see where our money is going and to feel the gratitude in the room.”

– Jasmin Barry-Keen, Impact100 SA Member since 2019

You can be as involved as you like; attend our member events throughout the year to learn more about our grants process, join one of our volunteer committees to help keep Impact100 SA growing, or cast your vote at our Awards Night and watch as we empower local not-for-profit organisations in their pursuit of service.

Becoming a Member


Becoming a member of Impact100 SA means you become part of a community of donors addressing social challenges and creating sustainable change. Your membership gives you the power to vote for causes you believe in to win up to $100,000 in grants. The more members we have, the more grants we can make.

This will take you to a third party site for the Australian Communities Fund. Donations are made to the Impact100 SA Fund, a sub-fund of the Australian Communities Foundation.

You will automatically receive your tax deductible receipt through this process.
