Voters at several Sutherland and Cronulla booths were confronted with a Hitler lookalike on Saturday spruiking the Australia First Party.
"Steve the national socialist'' was the creation of a Sutherland Shire resident who visited at least three polling places clutching a poster of "Kitler'', a black and white cat with markings reminiscent of the dictator's moustache.
"Steve'' also wore a narrow moustache and a red armband featuring a swastika.
A satirical video of the visits was posted on YouTube late on Sunday night.
But the party's Sydney branch chairman Jim Saleam wasn't laughing about the stunt yesterday.
"There will be a complaint lodged regarding two men with a video camera who visited several voting places on Saturday,'' he said.
"They have committed a series of electoral breaches, including handing out false and misleading information to voters.''
Mr Saleam said the complaint would include at least two websites the party believed were connected to the incident.
"There are a number of standard lines people tend to trot out when they want to oppose us,'' he said.
"This Nazi rubbish is one of them.
"They went down like a lead balloon at most booths anyway, but it is actually quite a serious incident and we will be following through with a complaint.''
"Steve'' said he had been inspired to make his video after reading about the party in the media and on the internet.
"Most people took it with a smile and a laugh,'' he said.
"You can see from the video we approached it in a polite, non-threatening way.
"Some people were a little surprised at first but it was very clear we were being humorous about the whole thing and that was generally the spirit in which it was received.''
