Federal MP Rebekha Sharkie has called for an investigation into claims robocalls sent to voters in her Adelaide Hills electorate of Mayo are impersonating her and is now seeking a recording of the messages.

Ms Sharkie said Mayo voters have received robocalls in the lead-up to next month's federal election that either impersonate her or use audio of her speaking.

"It appears from the emails I've received from people and other messages, my name is being used and people believe there is a robocall coming from me," she told the ABC.

"It's quite muffled from what people have said to me, but certainly people can hear my name."

The ABC has not heard a recording of the call. Ms Sharkie said she did not have a recording, but hoped locals would have it saved in their voicemail inboxes.

"I'm really keen to get a copy of that robocall, because I've never sent a robocall to anyone and never would," she said.

"In fact, we've put legislation into Parliament to ban the robocall so it is really concerning."

Mayo voter Jane Norris said she received a call claiming to be from Ms Sharkie about 10:30pm, and said she thought it was "dodgy".

"The number was withheld. The voice said 'this is an automated call from Rebekha Sharkie' and then followed with 'press one for agree' for a range of questions," Ms Norris said.

"Some of the questions were rather strange.

"I can't quote exactly, but what stands out in my memory is being asked something like 'do you agree with Rebekha's decision to always vote with Labor on bills'. Because I know Rebekha has not always voted with Labor I found this very strange.

"I actually hung up before the survey was completed."

Labor and the Greens have denied issuing the robocalls, and the ABC has contacted the Liberals for a response.

There is no suggestion any political party is responsible for the calls.

"The Liberal Party is not using robocalls in the electorate of Mayo," a campaign spokeswoman said.

Ms Sharkie wants the matter investigated.

"I have been given some phone numbers but in most cases it's from a private number," she said.

Voters across Australia have already been inundated with separate messages from figures including Clive Palmer and Senator Cory Bernardi.

On Wednesday, ABC Radio Adelaide listeners confronted Senator Bernardi over the unsolicited text messages but he defended his use of the technique.

"I use a lot of publicly available databases and any information we can gather," Senator Bernardi said.

"It just seems to be the most effective and efficient means of communicating with people."
