I just had my surgery, and I applied to release the funds back in October. It took a month to approve (Normally 10 days), but the letter they post to advise the amount and what to do next got lost 3 times. (thanks Aust post). I finally got the money in my account 2 weeks before my surgery. I submitted a letter from the surgeon, one from my doctor (GP) and one from my pain management Dr. It was a long process but worth it.
