We don't expect you to be reading these documents every game day, but they may come in handy when you are up to your third appointment of the day, each of different grades, or are calmly discussing aspects of the match with coaches, managers or other referees.
These documents (and many others) are all listed on the library page of this website, but consider this shortlist to either print out or have downloaded on your phone for quick reference:
1) Game Management Guidelines
2) Competition Rules
3) School Competition Rules
4) Grade Law Variations
