Hi Theadora,
Lived experience / peer support workers are definitely gaining more traction. If you are in the Sydney area, specifically the South Eastern Local Health District, I know they have a college called The Recovery College at their Safe Haven Hub. They have short courses / lived experience worker run workshops on getting into the space and it's free. There is a need for it within the public health system, and in support work for NDIS, youth work, aged care, and many other fields. It's not so much about your qualifications, though that will obviously help, but more about you sharing your story on recovery and offering hope when the people you support may not be able to hold hope for themselves. Empathy and compassion and judgement free are most important, and from what I read on your post, I feel that you have all of that and more. Most roles will pay for you to go through the Cert III Peer Worker TAFE course.
I hope this has been helpful for you and wish you all the best on your journey!
