IGN has a scan of the Australian OFLC report on Fallout 3.<blockquote> "The drugs depicted are fictional; drugs are depicted as stylised icons on a menu with the drug use itself not depicted. Whilst navigating a post-apocalyptic futuristic landscape, players can invoke the use of a variety of "chems" listed by fictitious names which include "Buff", "Rad-X", "Psycho" and "Ultrajet". Within the context of the game's narrative, the player may choose to make use of these "chems" to alter the physiological characteristics of their character in the game."

In the minority view of the Board the drug use in the game is in excess of the general rule applied under the Guidelines. The drugs are unambiguous in their visual representations, which include pills and hypodermic needles, and are related to incentives and rewards in that the incentive to take the drug is that progress through the game is achieved more easily and the reward is an increase in the character's abilities. The game therefore warrants and 'RC' classification.</blockquote>It seems drugs haven't even been removed, just the "offensive" ones, which were too close to their real-life counterparts for comfort (morphine, crack pipe). The report is vaguely worded so one can't be sure, but it seems the censorship of Fallout 3 in Australia is really light.
