Left 4 Dead Banned in Oz

So, continuing the Left 4 Dead 2 drama, first the game was boycotted by a group on Steam, now the controversial game has been banned in Australia. The melee weapons and the amount of gore were allegedly a big part in the decision.

Valve is disappointed at this, and responded thusly:

"We were surprised to hear of this news yesterday."
"Obviously, everyone at Valve is pretty bummed."
"It would be a shame if folks in Australia, or anywhere else, are unable to purchase Left 4 Dead 2 because of a ratings issue."
