The ASIC the company will organise. However if you want to speed up the process slightly (only by a matter of days and is not required) you can bring some information day one to help complete the forms.
Passport, addresses for the last 10 years (this is annoying). If you were overseas in those 10 years, a police record check from the countries (Australia you can just sign a form to release it).
The only other thing, you will get sent out is some pre course material before he starts. It does pay in my opinion to go through it a little. Its not essential, some people in my course did, some didn't, and everyone got through the theory portion unscathed. The first 8 or so weeks are very intensive, a massive amount of new information is being dumped on you. Anything you already have a vague understanding of beforehand will lessen that load.
Good luck to him.
