Where do I stand during the match?

There is one assistant referee or touch judge on each side of the ground. You remain in touch, except when judging a kick at goal, when you stand in in-goal, behind the goal posts (Law 6.22).

Each assistant referee or touch judge carries a flag or something similar to signal decisions. For a kick at goal, one of you stands at or behind each goal post.

If the match organiser nominates one, a reserve assistant referee or reserve touch judge is situated in the perimeter area.
