About 3Bridges and Volunteering 3Bridges is a registered charity and not for profit organisation, providing a variety of support services to the communities of South East and South West Sydney. Over the past 40 years, with services from early years, through to aging well, we have provided an array of solutions to make a positive difference in our local communities. We assist the lives of many by building happier, healthier, connected, and more engaged, valued and enriched communities. Volunteering involves contributing some of your own time, to help make a difference in supporting our community. The 3Bridges volunteering program is flexible and supportive and we will train you with the required skills on your volunteering journey, to assist making a positive difference in your life, and in the life of those around you.
