Good morning and welcome @chen64
I'm really happy you've received the DSP. This is really difficult to achieve given the amount of paperwork involved.
Applying and registering for the NDIS (National Disability Insurance Scheme) if it's up and running in your state, would be the next step. Not sure where you are though. It's been active in NSW for quite a while now. They case manage disability clients one-on-one and would have the answers you're after.
Otherwise, a visit to your nearest Centrelink office might be better. It depends on your consultant I'm afraid; some are really knowledgeable and some don't have a clue. I think making an appt telling them what you're after might be more productive than just dropping in. The Centrelink website may have what you're looking for too.
Good luck with everything!
Hope
