While we can’t recommend specific support coordinators, we do highly recommend support coordination if you are having issues managing your plan. Searching for NDIS support coordinators in google for your area as well as going to: https://www.ndis.gov.au/participants/working-providers/find-registered-provider should allow you to find what you need.
From here you can navigate to your area and download the PDF of providers for your state before searching for support coordination in here. As previously stated we cant recommend specific support coordinators, its important that you choose what fits best for you.
