A website set up by the SA Liberals is among material deemed "misleading" by the state's Electoral Commission, which is warning voters to be wary.

The commission said a range of dodgy advertisements, which could be wrongly perceived as coming from the commission itself, had been delivered to mailboxes and posted on social media during the current election campaign.

It said the material, which was brought to its attention this afternoon, all appeared to be from the Liberal Party.

"Examples of these advertisements include a flyer distributed to letterboxes requesting personal details to receive early voting information," the commission said in a statement.

It also includes "early voting advertisements on Facebook" which link to a website called Vote Early SA.

The only reference to the Liberals on the front page of the site is a line at the bottom in small and soft font, saying it has been authorised by Liberal state director Sascha Meldrum.

The commission said it was concerned about "misleading information provided to South Australian voters".

"[The commission] has been contacted by electors who believe this information was distributed or endorsed by the commission," it stated.

"This is not the case and the commission confirms that it has had no involvement with the creation or distribution of this material or the website."

The commission said it was still considering its position and had not decided whether it would take action over the advertisements.

Penalties for publishing misleading material include fines of up to $25,000.

In 2010, the Liberals railed against a Labor tactic that involved party workers, who were wearing shirts that said: "Put your family first", distributing how-to-vote cards advising Family First voters to preference Labor.



Ms Meldrum has been contacted for comment.
