I have a solution for Valve:
Allow users of Steam to buy Left 4 Dead overseas and enter the code to activate it on Steam even if they live in Australia and play it online from Australia.
The law only says the game cannot be SOLD without a rating, not a ban on mere ownership. A serious Aussie gamer could take a trip to NZ or some other country in the free world, there shouldn't really be anything stopping Valve hosing aussie gamers playing Left 4 Dead online down under, they can reasonably assume they legally bought it outside Australia and brought it in.
