Or whilst on the choccies theme, a terribly common expression here (and maybe also outside OZ?) is:
chock-a-block. Meaning anything completely full. 100% capacity.
And again not sure it this is used outside OZ
but the term used universally here to stop a vehicle from rolling down a slope, and the item used to do it with is a "chock".
Chock the wheels. Use a chock etc. Can be a brick, piece of wood or metal or a rock - whatever.
