The Department of Parliamentary Services signed off last week on new procedures for responding to serious incidents in the building.

The material was produced after ex-ministerial adviser Brittany Higgins went public in February with allegations a former colleague raped her in parliament house in March 2019.

DPS secretary Robert Stefanic and one of his deputies, Cate Saunders, confirmed at a Senate estimates hearing on Monday they have not watched the video.

Security branch assistant secretary Leanne Tunningley, who signed off on the training, is the only executive to have seen it.

"It just doesn't seem like people are taking it seriously," Labor senator Katy Gallagher said.

Mr Stefanic and Ms Saunders intend to view the training video, which is designed for parliamentary security officers.

"I don't want to leave you with the impression that we're not taking this seriously," Mr Stefanic said.

"We've dedicated, I think I could confidently say, hundreds of hours into ensuring that our policies and processes are robust and that we have made improvements.

"I wouldn't characterise not having seen the video as being not concerned about the seriousness of this."

He said the video was a visual aid for written training material over which executives had oversight.

Senator Gallagher said new training came into place eight months after Ms Higgins' allegations were made public.

"I just thought something like this that has come out of the whole Ms Higgins saga, maybe the secretary and deputy secretary would have watched the video," she said.

Mr Stefanic said a serious incident was defined as something that causes harm, including people appearing to be affected by alcohol or drugs behaving in a way not suitable for work.

Factors include people being visibly distressed, undressed, engaging in sexual behaviour, engaging in or being the victim of verbal or physical abuse and illegal behaviour.

Bruce Lehrmann has been charged with sexual intercourse without consent over the March 2019 incident involving Ms Higgins.

He has instructed his defence to enter a plea of not guilty with the case due to return to court on November 5.

Meanwhile, the government has rejected a claim by Australian of the Year Grace Tame that she was sidelined in the development of a new national strategy to prevent child sexual abuse.

Asked on the ABC last week whether she had been involved in the drafting of the strategy, Ms Tame said: "No."

One of the ministers responsible for the consultation, Ben Morton, told parliament Ms Tame had been involved in consultation in March, May and June including talks with him in Tasmania.

"I thank her for her insight," he said.

The details of the plan are due to be released later this week.
