The Australia Classification Board (ACB) is the statutory classification body of Australia. It was formerly known as Office of Film & Literature Classification (OFLC) until 2006.
In late 2012, Australia added an 18+ rating so certain mature games wouldn't have to be censored or not released in the region at all. The first game to get such a rating was Ninja Gaiden 3: Razor's Edge.
In August 2014, legislation was passed to revamped the board to make it more modern. This changed how games were rated completely. It greatly reduced both the time and the cost for a game's ratings. Free apps are also required to be rated as well. This allows eShop games to come to the region much easier.
