Changes to the way outdoor advertising is regulated in Queensland, which could lead to the “G-rating” of all content, have been foreshadowed by Attorney-General Jarrod Bleijie.

In a letter tabled in Parliament on Wednesday, Mr Bleijie said community concerns about outdoor advertising in the state led him to consider “the appropriateness of the current model” of control.

Rip and Roll posters sparked debate about ads in public spaces.

His comments came in response to a petition from the Australian Christian Lobby's Wendy Francis, who has been a central figure in several high-profile disputes about advertising content and in 2011 launched a campaign calling for “G-ratings” on billboards.

Ms Francis's calls were summarily rejected by a federal parliamentary committee that year. However it was recommended that if the industry failed to lift its game by June 2013, the government would intervene.
