"when players pick up a prostitute in the Australian version, there is no way to select a 'service' from the prostitute. The sexual intercourse sex animation has also been completely removed, so players will only see the car bounce from a locked rear-view. In the uncut version, after selecting a service from the prostitute, players can rotate the camera to see the prostitute's actions.
Also in the Australian version, no blood pools will appear beneath a dead person after shooting or stabbing them to death. There are blood splatters, but no blood pools. In the uncut version, blood will slowly ooze out from under a body, and it is possible to create bloody footprints by walking through the blood, or bloody tyre tracks from driving through it. Finally, when Niko or other NPCs are injured in the uncut version, light blood patches appear on their bodies which basically represent bruises/bullet wounds."
