The woman who began a successful petition for the removal of a game that requires players to bludgeon Aboriginal Australians to death is pushing for an explanation as to why Google and Apple hosted the app in their stores.

The Turnbull government is also demanding answers, with Communications Minister Mitch Fifield ordering a review into the "appalling" episode.

Georgia Mantle, a student from St George, launched the online petition on Friday evening after learning of the racist game, Survival Island 3: Australia Story 3D via Twitter.

Within hours, thousands of people had signed the petition, calling for the immediate removal of the game from Apple's iTunes App Store and Google Play and demanding an apology from the app's developers.
