Opposition Leader David Speirs will seek public comment and then bring legislation to parliament to end what he says is the unsightly spectacle of thousands of posters in public places during election campaigns.

The proposed laws would prohibit their use along public roads, with limited exemptions for areas near polling booths.

"After a number of recent elections, it's clear many people are sick of the visual pollution created by corflutes," Mr Speirs said.

"These posters and the cable ties used to attach them to poles also have a significant impact on our environment when they're disposed."

Mr Speirs said he led by example and chose not to display posters in his electorate during the March state election campaign.

He said that move received strong support from his local community.

Premier Peter Malinauskas said a ban on posters was not high on the government's agenda.

But he said it would consider any "legitimate proposition".

"We're naturally willing to contemplate any options put on the table to determine whether or not they're in the best interests of democracy in South Australia," he said.
