My observations are that not all companies grant access to their manuals to newly appointed staff as early as the type rating stage. It could be that you'll only get your hands on the company documentation once you've passed the type rating and you're starting the operator conversion training. However, as long as you're a trainee, the ATO has to provide you with all relevant documents. Perhaps there will be some self-study part to the course before you start the face-to-face part in the training centre. Most often, that's in the form of a CBT. Drop an email to your ATO and ask for details, that's what I would do.
