I have been doing some research and found NSW Trustee and Guardian can help to set it up, I think they just help to refer a lawyer, who will charge $220. Probably a very standard document doesn't take much time.
Also rang a couple of lawyers directly, they want to charge by time rather than a set fee, because it can be a complex matter and they want an appointment to discuss further. I guess by that they mean to start charging.
I have since downloaded both general and enduring POA forms (have not validated if they are the correct or current, but got an idea from them), and if I understand the process correctly, the lawyer is there to certify the form and possibly to go over the wordings and explain as needed. Is that right? They are not the attorney.
