Queensland’s Attorney-General could become the moral arbiter of roadside billboards if advertisers post sexually explicit images.

A state parliamentary review into outdoor advertising was set up in April after the Australian Christian Lobby presented the government with a petition demanding a crackdown on sexually explicit images and slogans.

The Rip and Roll billboard campaign caught the attention of the Australian Christian Lobby in 2011.

Nine months later, MPs on the bipartisan inquiry recommended an industry body be set up with the power to sanction an advertiser even if no complaint is made.

If an advertiser breaches its ruling, the Department of Justice or Attorney-General Jarrod Bleijie would ‘‘pre-vet’’ future outdoor ads.
