Some councils along the New South Wales north coast could soon ban camper vans emblazoned with offensive slogans.

Byron Shire Councillor Duncan Dey has lodged a motion calling for signs to be set up that tell the drivers of the controversial and intentionally offensive Wicked vans that they are not welcome.

Cr Dey wants vans with offensive slogans banned from council-owned caravan parks.

“The motion has been looked at by council staff,” Mr Dey said.

“What they're saying is that enforcement on offensive language is not something that a council can do.

“But any landowner can do it and so council could do it in relation to those vans trying to enter onto council property like a caravan park.”

Some councillors say they want the Federal Government to legislate against offensive slogans.

“Legislation making it unlawful for a person to engage in offensive behaviour based on another person's gender identity, sexual orientation or related grounds, that would wrap up the notion that you could write anything like that on a van because it would be illegal,” Cr Dey said.

Local delegates are expected to take a motion on the issue to the upcoming national conference of the Australian Local Government Association in June.

The Ballina Council will discuss the Wicked vans controversy this week, with a motion also calling for the NSW Government to take action against them.

“We have no control over the state roads so therefore it will actually be a letter to the minister to encourage him to make changes in NSW,” Deputy Mayor Robyn Hordern has told reporters.

“I want it to be clear that I see these messages as being coarse, disgusting, and simply quite offensive.

“They're not appropriate to have parading up and down our highways.”
