Hookers not cut from Aussie version.
Narayan Pattison IGN AU
Australia, April 27, 2008 - After having played the Australian Xbox 360 box copy thoroughly we're happy to report that the "minor differences" Rockstar admitted were made to pass classification haven't made any impact to the GTA experience that our seasoned eyes can spot.
The infamous act of picking up hookers in your car remains intact in the Australian version. This was the most likely cut to be made to appease the OFLC and the fact that it hasn't been made indicates that the actual change must be very minor indeed.
Fans of the raunchier side of GTA can also breath easily upon hearing that strip clubs, complete with private lap dances are also completely accessible and intact in the Aussie version. Other potential items for the cutting room floor were getting drunk and being able to then drive while drunk, but both of these options are still present.
Our best guess is that something has been trimmed from a cut-scene. So, although we can't say for sure what has been cut, we would urge people planning on boycotting the Aussie version to reassess their plans. Considering hookers, lap dances and drink driving have all sailed through you're very unlikely to even notice, let alone miss, whatever was snipped.
