Volunteers help charities in many ways - from preparing food, visiting elderly people, to being a board member.
If you are interested in volunteering for a charity, you can search the ACNC Charity Register to find the contact details of a charity that you want to help. It's often a good idea to ask the charity what type of volunteers they need, to see if your skills suit the type of help they are looking for. You could also use a volunteering matching website (some are listed below) to try to find a charity that is searching for volunteers.
Volunteering Australia is is the national peak body for volunteering, working to advance volunteering in the community.
