I'm particularly interested in design and layout of all the necessary forms to be used.
The forms are unique to the organisation; you make up whatever forms you need for your specific operation, in whatever format you want.
The manual describes an individual organisation's method of operation. Forms will include training documentation, which is readily available from AFE and Pooleys, and the various records you deceide to keep which are individual in nature.
If you are acting as a consultant, then you need have a firm grasp of what you are doing and be prepared to generate the necessary documents based upon the published requirement. Unless you are setting up a new ATO, you may be wasting your time.
