Tasmanian police have travelled to Queensland to interview the woman who alleges she was sexually assaulted by veteran Liberal MP Rene Hidding.

Mr Hidding, 66, resigned from the Tasmanian Parliament on Monday, describing the woman's allegations as a "false and malicious attack".

He said the false allegations were best dealt with as a private citizen, and his focus was on protecting the privacy of his family away from the "fishbowl of Tasmanian politics".

The woman called on Police Commissioner Darren Hine to investigate why her original contact with police was not followed up years ago.

"The appropriate action and due diligence and duty of care should have been done in 2013 when I first contacted the police station," she said.

'Subpoena the diary', police urged

Tasmanian police said they had no record of a complaint being made prior to 2019, but yesterday afternoon said they were investigating the woman's claim of an earlier report.

The woman wants an audit of Premier Will Hodgman's diary.

The woman told the ABC earlier this month she contacted the Premier's office about the allegations.

Will Hodgman's office never followed up the call.

"I will also be suggesting to police to investigate and subpoena the diary, because the receptionist at Will Hodgman's office took my name and mobile number," she said.

On Monday, Mr Hodgman confirmed his office received a phone call from someone in February relating to allegations.

"My office did receive a call from someone who wished to remain anonymous in early February. But at no time was my office, myself, my staff, made aware of the nature of any allegations," he said.

Hidding exit forces Hodgman to delay Parliament

The allegations against Mr Hidding have sparked a crisis in the Hodgman Government.

Late on Tuesday afternoon, the Premier announced he was delaying the return of Parliament by a week to allow the electoral commission to complete the recount for Mr Hidding's seat in Lyons.

Mr Hidding is likely to be replaced by Break O'Day Councillor John Tucker, who has confirmed he will nominate for the seat.

The move means Mr Hodgman will avoid the ugly prospect of governing in minority — which would have been the case if Labor had not granted a pair for the seat vacated by Mr Hidding.

Labor leader Rebecca White said Mr Hodgman was "simply incapable of facing scrutiny over the Rene Hidding scandal and was prepared to demonstrate to all Tasmanians that he would rather hide than face serious questions".

In a statement released on Tuesday, Ms White said Mr Hodgman was "now running away from governing and showing extraordinary cowardice".

"This is a government in absolute turmoil. Mr Hodgman was elected by the people of Tasmania to do his job, not hide from it."

Parliament will resume a week later on March 19.
