After the 2008 election, many distributors "over ordered"
They hoped that they might get 5-10% of the order and then they could cancel the remaining order.
The back order is fictional as every shop has placed orders with multiple distributors and the volume is not real.
If an AWB is passed, they will build up until the last day possible.
If it does not pass, the demand will drop...
Once we get 1-2 new Supreme Court judges appointed by the current government, all bets are off....
