Australia has introduced a new colour-coded system to make the age ratings featured on games and DVD(this one is for you forahobby) but despite calls from the OFLC they will not be introducing a new 18+ rating for titles containing adult content.
Although "R" ratings exist- the highest classification which can be awarded to games in Australia is 15+



Any titles that Have Sex or drug usage, or would have a higher classification level than the 15+ will be banned from sale (Examples: NARC- who would want to buy this game anyway? and Lisure Suit Larry: Magna ***** Laude
are titles that were refused classification and are now banned PERMANENTLY!!)
