This support group has a helpline for people with chronic pain. You can call and speak with someone from 7am to 7pm.
The helpline is a free service run by volunteer staff who live or have previously lived with chronic pain themselves. Therefore, you can also volunteer with this organisation. APMA is also an advocacy organisation working to improve the management of pain for Australians. There are benefits as a member you can also look into.
