The petition, addressed to Wicked Campers Founder John Webb, was launched by a Sydney mother after her daughter was exposed to the group's slogan that read "In every princess, there's a little slut who wants to try it".
"A few days ago, I went to pick up my 11 and 7 year old daughters from a holiday stint with my parents," Paula Orbea wrote on her blog.
"As we greeted each other with hugs, my 11 year old did not hesitate in telling me, with great concern, that she saw something terrible when she was in the car with my dad – a van that said all girls were sluts who want to try it just once."
In her official complaint to the Australian Standards Bureau, Orbea's daughter wrote, "I am a little girl and I am not a slut."
Some of Wicked Camper's other slogans include: 'Fat girls are harder to kidnap', 'A wife: An attachment you screw on the bed to get the housework done' and 'I wouldn't trust anything that bleeds for five days and doesn't die!'
Over 100,000 people have now signed the petition 'Eliminate misogynistic and degrading slogans and imagery' on change.org.
Numerous complaints against Wicked Campers have been upheld by the ASB, however, the group are able to disregard the rulings due to Australia's system of industry self regulation, meaning there are no penalties, fines or legislation to enforce advertisers to comply.
"Time and again, we have seen Wicked Campers ignore calls from the ASB to keep its slogans in line with community standards," Wendy Francis from the Australian Christian Lobby said.
"Our children and young people will continue to be exposed to such inappropriate content if our governments fail to intervene."
The ACL has since called on state governments to introduce laws regulating outdoor advertising.
