It might help you to pay a little more attention before posting.
The line just below the part you made bold completely negates your entire point.
I know retailers are not the full picture and frankly i don't care, just like the consumer does not give 2 shits. If something is not done to fix this issue the entire chain is going to fall over, starting with retailers.
You may not see this as fair because the retailers will be the first to pay the price, and maybe it is not, but that won't stop it from happening.
The suppliers will get theirs once there are no retailers left to sell their over-priced products.
You can shift the blame, you can make excuses and it won't change a thing. If something big does not change with the retail industry in Australia, it is f**ked.
:edit:
As bad as it may be for retailers, i think Australia's retail industry needs a big crash, it seems like the only way to purge the country of the greedy suppliers and inefficient double handling that's going on, not to mention the shameless price gouging by people like Steam and iTunes.
These suppliers won't do anything until something happens to hurt them financially. Unfortunately for retail, they will suffer long before the suppliers do.
