UPDATE: LNP candidate David Janetzki has denied any connection to robocalls made to Toowoomba South voters this week which labelled independent candidate Di Thorley "divisive".
"I'm not aware of any robocalls," Mr Janetzki said.
The candidate said any questions relating to issues like that should be referred to his party.
"I'm fighting hard for every vote and talking to locals about our future," he said.
Are automated opinion phone polls fair?
This poll ended on 17 November 2016.
This is not a scientific poll. The results reflect only the opinions of those who chose to participate.
"I'm absolutely focused on Saturday and trying to connect with as many voters as possible."
An LNP spokesman said: "The LNP does not engage in push polling.
"Any person running for public office should be able to stand on their record.
"Research by the LNP on issues of importance to the people of Toowoomba South indicates that Ms Thorley's divisive record as mayor is a significant concern to voters.''
The automated survey was conducted by Brisbane-based polling company ReachTEL.
A spokesman for the company said it was unable to disclose who had paid for the survey.
EARLIER: The Chronicle has obtained a recording of an automated phone survey that takes aim at Di Thorley, labelling the former mayor as "divisive".
The robocalls started targeting Toowoomba South voters this week.
The automated survey by Brisbane-based polling company ReachTEL asks residents to rate the six candidates in the running for Toowoomba South.
The survey takes a bizarre turn when it labels Ms Thorley as "divisive".
"When she was mayor of Toowoomba, many locals described Di Thorley as divisive," it stated.
"Do you believe the future of our local area is best served by a divisive member of parliament?"
ReachTEL followed that by asking the age and income bracket of residents.
One person who had been called four times by ReachTEL blamed the LNP for the phone calls and said it was proof the party's members were "running scared".
During the Federal Election, the Coalition consistently attacked Labor for using "robocalls" that encouraged voters to back Opposition Leader Bill Shorten as part of its Medicare scare campaign.
Ms Thorley said the calls were the latest example of LNP scaremongering that had also featured advertising, flyers and letters.
"Voters must not reward this bullying behaviour," she said.
LNP candidate David Janetzki has been contacted for comment.
The Labor Party is not running a candidate in the Queensland by-election.
It is contested instead by candidates for Katter's Australian Party, the Greens, Family First, the LNP, Rob Berry and Ms Thorley.
The by-election was called after the LNP's John McVeigh contested and won the seat of Groom in the Federal Election.
