The WA Electoral Commission has raised issues with candidates and their representatives who have been repeatedly harassing voters and the public, as well as blocking traffic near early voting centres, two weeks out from the WA election.
In the first two days of early voting more than 50,000 people have already cast their ballot in-person, but Commissioner Robert Kennedy said he received "several reports of harassment and inappropriate behaviour by volunteers and representatives of political parties".
In some cases the behaviour was so bad the Commission was asked to permanently remove some political representatives.
"Unlike polling places which are usually located in schools and operate on a Saturday, early voting centres have to co-exist with neighbouring tenancies.
"Taking over parking bays and parking cars all day outside other neighbouring businesses is creating justifiable concerns from small business operators and electors who are simply trying to cast their vote."
Mr Kennedy said the complaints were largely from businesses and property owners in the areas near voting centres.
He said some of the inappropriate behaviour happened near court houses, where political volunteers or representatives may have caused extra upset to people who were already in a "distressing and uncomfortable" position.
Commissioner Kennedy said several property owners and centre managers had already asked for some supporters to leave and not return.
"This number is likely to grow if the behaviour of your volunteers and supporters does not improve," he said.
Speaking to ABC Radio Perth, Mr Kennedy reminded voters they did not have to accept any "how to vote" material offered to them, at any time, even if they were voting.
He said the Commission only had control of the six metres in front of the voting centre's entry, but warned some volunteers were trying to "nab" voters as soon as possible which was causing a bad reaction in some cases.
The aim of the letter was to remind candidates and their representatives to be sensible, he said.
