Australian political leaders including Prime Minister Scott Morrison have apologised to staffers who have endured decades of bullying, harassment and sexual assault inside parliament and other government offices.

       The presiding officers of the House of Representatives and Senate delivered the apology on Tuesday on behalf of a cross-section of parties as part of a statement acknowledging a toxic workplace culture.

       That culture was exposed by Australian Sex Discrimination Commissioner Kate Jenkins' investigation.

       The investigation was triggered by former government staffer Brittany Higgins, who went public a year ago with her allegation that she had been raped by a more senior colleague in a minister’s Parliament House office weeks before the 2019 election.

       Ms Higgins said she felt she had to make a choice between reporting her allegations to police or continuing her career. She quit her government job in January last year and reported her allegation to police.

       Ms Higgins was one of seven women who were given exemptions from a pandemic ban on viewers sitting in the public gallery of the House.

       Mr Morrison thanked Ms Higgins for the courage she had shown in making her allegations.

       “I am sorry. We are sorry. I’m sorry to Ms. Higgins for the terrible things that took place here,” Mr Morrison told parliament.

       “The place that should have been a place of safety and contribution turned out to be a nightmare. But I’m sorry for far more than that. For all of those who came before Ms. Higgins and endured the same, but she had the courage to speak, and so here we are,” the PM added.

       More than 1,700 people made contributions to Ms Jenkins’ report, including past and present staffers.

       Her report found 37 per cent of people currently in parliamentary workplaces had experienced bullying and a third had experienced sexual harassment.

       Deputy Prime Minister Barnaby Joyce told parliament he joined in the apology and in “acknowledging that we will do better.”

       Revelations in 2018 that Mr Joyce was expecting a baby with former press secretary Vikki Campion led to then-Prime Minister Malcolm Turnbull banning his ministers from having sex with staff. Mr Morrison has maintained the ban.

       Mr Joyce in 2018 was married with four children. He has since married Ms Campion with whom he has had two children.

       House Speaker Andrew Wallace told parliament that action was already being taken to improve the workplace culture.

       Last year, an independent complaints process was established. Lawmakers and staff had also undergone professional workplace training, Mr Wallace said.
