The office of Dr Phelps, the member for the Sydney seat of Wentworth, has received dozens of calls about the emails and Facebook messages.

One of the emails, obtained by AAP, falsely states she has been disqualified from election because she "is a Jew and entitled to automatic Israeli citizenship".

Dr Phelps is an Australian citizen and her parents and grandparents were born in Australia.

It also urges voters to "shred" her campaign posters and asks them to vote for Liberal candidate Dave Sharma.

The emails have been sent using a variety of names.

"The content of the emails is very disturbing," Dr Phelps said.

"Whichever individual or group is responsible is trying to influence the outcome of an election and I think they should be investigated and brought to justice."

Mr Sharma had condemned the emails, saying he had also referred them to the Australian Federal Police.

An AFP spokesman said a referral had been received and would be assessed in accordance with the AFP's standard protocols.

The website Pastebin has published a draft email which includes the disturbing content distributed in Wentworth.

Comments was being sought from Pastebin, a site used to share large amounts of text online.

Last month, hundreds of Dr Phelps' posters were stolen within a week of them being erected around the electorate.
