The Crate Theatre came about via many influences, the greatest being an alternative use for an iconic everyday object, the milk crate.
In the UK for example, the milk crate is used in a different way to that of Australia. A milk float carries pint milk bottles in crates for delivery to the door while collecting empties for cleaning and refilling. The crates have dividers to keep the glass bottles separated from each other, pretty much restricting use for carrying much else. The Australian crate however, sturdy crate with a multitude of uses!
